[书]PERFORM-3D 原理与实例 – 第1章 : PERFORM-3D软件介绍

[Book] PERFORM-3D Theory and Tutorials Chapter 1 : Introduction of PERFORM-3D


  • 章节内容简介 [ Chapter Content Abstract ]

PERFORM-3D(Nonlinear Analysis and Peformance Assessment for 3D Structures)由美国加州大学伯克利分校的鲍威尔教授(Prof. Granham H. Powell)开发,由美国著名的结构分析软件公司CSI(Computers and Structures,Inc.)负责发行和维护,是一款致力于三维结构非线性分析和抗震性能评估的软件。

作为一款结构非线性分析软件,PERFORM-3D具有丰富的单元模型及强大的非线性求解器。软件支持的单元类型包括:线性和非线性纤维梁柱单元、各类梁柱塑性铰单元、纤维剪力墙单元、弹性板壳单元、粘滞阻尼器单元、屈曲约束支撑单元、橡胶隔震支座单元、摩擦摆隔震支座单元、支座弹簧单元、节点核心区、砌体填充墙等,可以用于抗震结构和减隔震结构的分析模拟。

PERFORM-3D软件提供了丰富的分析工况,具体包括:重力工况(Gravity Load Case)、静力Pushover工况(Static Push-Over Load Case)、动力地震时程工况(Dynamic Earthquake Load Case)、反应谱工况(Response Spectrum Load Case)、卸载Pushover工况(Unload Push-Over Load Case)、动力荷载工况(Dynamic Force Load Case),且各类工况之间的分析顺序可以自由衔接,能够满足大多数结构的弹塑性分析要求。PERFORM-3D软件采用了“事件到事件”(Event to Event)的非线性求解策略,在实际应用中发现,PERFORM-3D的非线性求解器具有较高的求解效率及良好的收敛性。

另外,作为一款结构抗震性能评估软件,PERFORM-3D拥有一套完善的结构性能评估系统,能够实现基于材料、构件及结构三个层次的抗震性能评估。

PERFORM-3D软件目前已广泛应用于我国的结构抗震研究领域及实际工程实践中,是工程界和科研界认可度与接受度较高的结构非线性分析及抗震性能评估软件。

PERFORM-3D (Nonlinear Analysis and Performance Assessment for 3D Structures), which is a powerful software that can provide nonlinear analysis for 3D-structure and seismic performance evaluation, is developed by Prof.Granham H.Powell Berkeley, California, USA. PERFORM-3D is released and maintained by a American well-known structure analysis software company CSI(Computers and Structures, Inc).

As a nonlinear structure analysis software, PERFORM-3D has abundant element models and a powerful nonlinear solver. Element types supported by the software include: linear and nonlinear fibre beam-column element, different kinds of plastic hinge element, fibre shear wall element, elastic shell element, viscous damper element, buckling-restrained brace element, rubber bearings brace element, friction isolation support element, support spring element, joint core area, masonry filler wall etc. Therefore, PERFORM-3D can simulate and analyse anti-seismic structure or seismic-isolation structure.

PERFORM-3D software provides all kinds of load case, including: gravity load case, static push-over load case, dynamic earthquake load case, response spectrum load case, unload push-over load case, dynamic force load case. The analysis order of different kinds of load case can join together freely, which can satisfy elastic-plastic analysis on most of structures. PERFORM-3D adopts “event to event” nonlinear solving strategy, which makes it high efficiency in solving rate and better convergence.

In addition, PERFORM-3D has a set of prefect seismic performance evaluation system, which can evaluate the seismic performance based on three levels: material, member and structure.

Nowadays, PERFORM-3D has been widely used in structure seismic research field and practical engineering application in our country, which is become a high reorganization and acceptability nonlinear analysis and seismic performance evaluation software in engineering research community.

 [Book] [PERFORM-3D Theory and Tutorials – Foreword] [English Version]


With the rapid development of economy and technology in our country, high-rise building, super high-rise building and complicated high rising structural system of all kinds appear in our country in recent years. It is not secure to use traditional seismic design method for these tall buildings beyond the code-specification. In present, performance-based seismic design is widely used in engineering. One of the most important difference between traditional seismic design method and performance-based seismic design method is that the force and deformation of structure under rare earthquake is gathered though nonlinear analysis and next seismic performance of structure is evaluated. Therefore, engineers must master a set of available and high efficiency structure nonlinear analysis software and understand the nonlinear analysis result of the software as well. Only in this way can engineers be able to complete the nonlinear analysis and seismic performance evaluation of structure.

PERFORM-3D (Nonlinear Analysis and Performance Assessment for 3D Structures), which is a powerful software that can provide nonlinear analysis for 3D-structure and seismic performance evaluation, is developed by Prof.Granham H.Powell Berkeley, California, USA. PERFORM-3D is released and maintained by a American well-known structure analysis software company CSI(Computers and Structures, Inc). As a nonlinear structure analysis software, PERFORM-3D has abundant element models and a powerful nonlinear solver. In addition, PERFORM-3D has a set of prefect seismic performance evaluation system. Nowadays, PERFORM-3D has been widely used in structure seismic research field and practical engineering application in our country, which is become a high reorganization and acceptability nonlinear analysis and seismic performance evaluation software in engineering research community.

Because PERFORM-3D is an English software, the manual that comes with the software involves lots of mechanical knowledge and structural concepts, which makes the beginners difficult to master the software. In present, books about PERFORM-3D are rare and each has its focus. In this case, author decides to share experience on learning elasto-plastic analysis and PERFORM-3D in this book, hoping to help readers in need.

To master a structure analysis software, we must have a better understanding of design ideas and theoretical knowledge involved. However, theoretical knowledge is boring. The best way to develop an interest on software is combining theory with practice. Therefore, the most common used material model, element types and analysis method in PERFORM-3D will be introduced in each chapter. Every chapter is concern with one topic, such as one type of material, element or analysis method. In the beginning of every chapter, it will give an introduction to theory and concept involved in the example. Through examples, basic principle, fundamental operation and definition of parameter are combined together, which makes readers learning more quickly.

[ Target Readers ]

This book is intended primarily for basic and intermediate users and also is a reference for advanced user. Application object includes: undergraduate and graduate student engaged in structural engineering and disaster prevention and reduction engineering; engineers and designers engaged in seismic design of bridge engineering; researcher who is interested in structural elasto-plastic analysis and seismic design based on performance.

[ Book Features ]

The main features of the book are as follow:

(1) Complete in contents. The common used model, function, material, element and analysis method is briefly introduced in order to let readers master PERFORM-3D completely and build models to analyse elasto-plastic analysis and evaluate seismic performance easily.

(2) Detail in explanation. According to different material, element and analysis method, every example is designed in detail for studying the software. Each example in this book gives the Step by Step operation and skills as well.

(3) Based on basic principles. Each element model or analysis involved in the book is given a detailed example after introducing the basic principle. In the example, it focuses on the selection of the parameter which makes readers acquire a better understanding to the theory.

(4) Abundant examples. This book is not limited to the theory explanation. There are nearly 20 examples in the book and the examples are taken from real experiments (low cyclic test, shake table test) and classic verify examples of other authority software (SAP2000, SeismoStruct). To ensure the validity of theory explanation, the reasonability of parameter selection and the accuracy of analysis, every analysis result of detailed example is compared with the analysis result of experiment accordingly or other authority software. Therefore, readers can learn software more quickly through these examples.

(5) Independence of chapters. Every chapter is concern with a main topic and the content of each chapter is independent. In addition, every example is designed for the chapter and the content of each example is independent. Therefore, readers can learn the required content and reduce the studying pressure.

[ Main Sections ]

The book is divided into 5 sections, totally 22 chapters.

Section I is “Fundamentals”, including chapter 1~2. Chapter 1 gives a summary of the characteristic of PERFORM-3D and introduces the design thought, interface composition, modelling and analysis function of the software. Chapter 2 introduces the fundamental procession of modelling and analysis in PERFORM-3D though introductory examples, which aims to let readers grasp the idea of modelling and analysis of PERFORM-3D.

Section II is “Theory and Examples”, which is the main part in the book, including chapter 3~13. Every chapter is concern with one topic, which is totally 11 topics. In the way of combing theory and examples, the content of material constitution, element model, analysis method, and result post-process in PERFORM-3D will be given a detailed introduction. The content relates to material model such as concrete, steel and masonry; relates to element types such as nonlinear fiber element of beam and column, concentration plastic hinge element of beam and column, shear wall element, infilled wall strut model, buckling restrained brace element, spring element, viscous damper element, isolator friction pendulum element, rubber isolator pendulum element, gap-hook element, deformation gage element. Though this part of study, readers can get a better understanding of fundamental principle of common used material and element and be able to model and analyse different type of element and structure.

Section III is “Comprehension Analysis Subject”, which introduces several comprehensive subjects, including chapter 14~17. Chapter 14 introduces reciprocation displacement loading in PERFORM-3D. Chapter 15 introduces seismic analysis under multi-support excitation in PERFORM-3D. Chapter 16 introduces basic theory and analysis of Pushover in PERFORM-3D. Chapter 17 introduces elasto-plastic analysis of the whole structure and structure performance evaluation in PERFORM-3D. Though the study of section III, readers can improve the ability in comprehension application.

Section IV is “Simulation of Dynamic Load Test of Structure”, including chapter 18~20, which is an actual modelling simulation of 3 dynamic load experiments: two shake table tests and a pseudo-dynamic test of full-scale frame. Thought numerical simulation of actual dynamic loading test, readers can feel the precision of numerical simulation in PERFORM-3D. In addition, the key issues which should be noticed in numerical simulation in PERFORM-3D. When PERFORM-3D is applied in actual engineering, readers should be aware that some problems can be simplified and some cannot be simplified.

Section V is “Common Errors and Warnings”, which summarizes some common errors and warnings in the application of PERFORM-3D and gives the solution.

评语 8

我与崔济东博士相识于其个人博客,多年来崔济东博士编写了大量的结合Perform-3D的小程序供大家下载,一定程度上推广了Perform-3D程序的应用。近年来,由于建筑体型愈来愈复杂,超限项目越来越多,由于《高层建筑混凝土结构技术规程》对于结构抗震性能设计提出了具体的要求,使得Perform-3D这样一款优秀的抗震性能评估软件得以广泛应用。

随着社会经济的发展,目前在抗震结构设计中,基于隔震、减震技术的消能减震结构越来越凸显其经济性。另人欣喜的是,本书不仅包含基本操作,特别是用大量篇幅并结合实例详细介绍了粘滞阻尼器、屈曲约束支撑、摩擦摆隔震支座、橡胶隔震支座等的力学模型及构件模拟方式。本人曾经担任过多个消能减震项目的专业负责人,推荐读者将此书作为使用Perform-3D进行消能减震设计的教科书使用。

评语 10

PERFORM-3D软件一直作为华阳国际动力弹塑性时程分析的主力软件,在很多工程中得到应用,如深业上城塔1(388米),塔2(299米),卓越1号(315米),万科云城(245米),华润大冲住宅群(200米),鸿荣源(240米),宏发(180米)等多个地产项目,今有幸读了崔济东博士《PERFORM-3D原理与实例》一书,感觉不吐不快。

作为一个PERFORM-3D软件的忠实粉丝,我认为PERFORM-3D软件是一款经典的弹塑性分析软件,模型数据库完善、算法可靠,代表了抗震工程研究的先进技术。通过在整体结构、构件、材料等方面定义目标性能水准,以地震反应后抗震“能力”与地震目标性能“需求”的比较来判断结构是否满足预期的性能目标,很好地实现了基于性能的抗震设计思想。

但该软件操作相对复杂、涉及的理论较多,对分析人员有较高的专业知识要求,使很多初学者望而却步。本书作者结合自己的心得与研究对PERFORM-3D软件进行了较为系统的讲解,书中包含二十余个算例,覆盖了PERFORM-3D软件常用的材料本构及单元模型,且各有侧重,具有很强的可操作性,且大多数算例立足试验,对工程应用有很好的参考价值。该书极大地缩短了PERFORM-3D软件的学习时间,相信通过阅读本书,读者能够得到结构概念、力学理论与软件应用水平等各方面的提高。

评语 14

PERFORM-3D作为弹塑性分析和性能化设计中的一个经典传奇,可以用下面这句话来形容:“一直被模仿,从未被超越”。要想成为软件的主人,而不是被软件奴役,就不单单要求会软件的基本操作,而是需要精通软件的各种基本假定。要想明白软件基本假定最好的方法就是与经典算例或实验进行对比分析,找到差异所在。崔济东博士这本书里具有很多这样的实例,非常具有学习价值,通过这些例子的学习,不仅能熟悉软件的基础操作,更能够加深对结构弹塑性分析基本假定的理解,从而真正驾驭软件。

[Chinese Version] PERFORM-3D原理与实例 —— 前言


随着我国经济与技术的快速发展,近年来国内各地陆续出现各种高层、超高层及复杂结构体系,很多建筑超出了现有规范的适用范围,对于这类超限工程结构,采用传统的抗震设计方法已无法确保其安全性,目前工程中主要的做法是采用基于性能的抗震设计方法进行结构设计。基于性能的抗震设计方法与传统抗震设计方法的一个重要的不同之处在于必须通过非线性分析获得结构在罕遇地震作用下的力与变形需求,并依此进行抗震性能评估。为此,工程师必须系统、熟练地掌握一套可靠高效的结构非线性分析软件并能够对软件的非线性分析结果做出合理解读,这样才有可能完成复杂结构的非线性分析与抗震性能评估工作。

PERFORM-3D(Nonlinear Analysis and Peformance Assessment for 3D Structures)由美国加州大学伯克利分校的鲍威尔教授(Prof. Granham H. Powell)教授开发,由美国著名的结构分析软件公司CSI(Computers & Structures Inc.)负责发行和维护,是一款致力于三维结构非线性分析和抗震性能评估的软件。PERFORM-3D拥有丰富的单元模型、高效的非线性分析算法及完善的结构性能评估系统,是一款同时适用于科研和工程的结构非线性分析软件,目前已广泛应用于我国结构抗震研究领域及实际工程实践中,是工程界和科研界认可度与接受度均较高的结构非线性分析及抗震性能评估软件。

由于PERFORM-3D为英文软件,软件自带的英文帮助文档又涉及较多的力学知识与结构概念,导致初学者很难在短时间里掌握软件的使用方法及理解软件的精髓。目前市面上关于PERFORM-3D的书籍较少,且各有侧重,对于PERFORM-3D软件的学习仍显匮乏。为此,作者决心将自己学习弹塑性分析与PERFORM-3D的心得整理成书,以书会友,希望能帮助到有需要的朋友。

众所周知,要想掌握一款结构分析软件,必须对软件的设计思路及涉及的理论知识有较好的把握,而理论知识是十分枯燥的,兴趣是学习理论知识的最好老师,而培养兴趣的最好方法是将理论和实践相结合。为此,本书将PERFORM-3D涉及的常用材料模型、单元模型及分析方法分成多个相互独立的章节进行讲解,每一个章节主要涉及一个独立的主题,如某种材料、单元或者分析方法,并针对该章内容设计一个本章特有的算例进行Step by Step地讲解,且在讲解算例前先对该章用到的理论知识及结构概念进行梳理,将软件的基本原理、基本操作、参数定义方法及使用技巧通过算例讲解有机地结合起来,使读者能够快速把握相关主题的关键点,并通过实例做到举一反三。

[ 读者对象 ]

本书主要面向PERFORM-3D软件的初级和中级用户,同时也为高级用户提供了有用的参考。适用的对象包括:结构工程、防灾减灾工程专业的本科生、研究生;从事建筑、桥梁结构抗震设计的工程师及相关设计人员;对结构弹塑性分析及基于性能的结构抗震设计感兴趣的研究人员。

[ 本书特色 ]

本书具有以下主要特点:

(1)内容完整。对实际应用中常用的模块、功能、材料、单元及分析方法均作了详细的介绍。力求使读者看完本书后能较为全面地掌握PERFORM-3D的功能,把握PERFORM-3D软件的精髓,轻松建立结构模型并进行弹塑性分析与抗震性能评估。

(2)软件讲解详尽。针对不同的材料、单元及分析方法均设计了具体配套学习的算例,每一个算例均给出了Step by Step的操作过程并有针对性地讲解软件的使用技巧。

(3)立足于基本原理。书中涉及的每一种单元模型或分析方法,在对其基本理论进行介绍之后,都有相应的具体算例,并在算例讲解的过程中着重讨论模型参数的选取方法,帮助读者加深对理论的理解。

(4)算例丰富。本书并不是一味地进行枯燥的理论讲解,本书共提供了近20个算例,且这些算例不是凭空设计的,绝大多数算例均来源于真实试验(低周往复试验、振动台试验)及其它权威结构分析软件(如SAP2000、SeismoStruct等)的经典验证实例。对于每一个具体算例的分析结果,都有相应的试验结果或其它权威软件的分析结果进行对比,以保证理论讲解的正确性、参数选取的合理性、分析结果的准确性。通过精心设计的算例,使得初学者在对某一专题的学习过程中可以有模板可依,达到立竿见影的效果,并且能举一反三。

(5)章节内容独立。每一章涉及一个主要的内容,各章内容之间是相互独立的。另外每一章的算例也是专门针对该章节进行设计的,各章算例之间相互独立。方便读者有针对性地进行所需内容的学习,同时也可以减轻初学者的学习压力。

[ 主要内容 ]

  • 题目:闲谈结构层间位移角

以下讨论暂不考虑重力二阶效应(P-Δ)。

根据规范给出层间位移角的定义:楼层层间最大位移与层高之比。设层间位移为Δ,层高为h,则层间位移角为Δ/h。

如图1所示,在结构某一高度H处作用一个水平力F,高度H处结构产生水平位移D和转动θ。由于高度H以上的楼层不受水平荷载,且不考虑重力二阶效应,则高度H以上楼层以高度H处的楼层为基准,发生整体平动和转动,整体转动角度为θ,整体转动导致上部楼层产生层间位移Δ,且有θ=Δ/h。根据规范规定,如果Δ/h超过了规定限值[Δ/h],可得出结论,高度h以上的楼层在没有受力的情况下“超限”了。

这里引用广东省《高规》第3.7.3条条文说明来解释上述现象:“……通常层间位移角以建筑物的中、上部楼层较大,即使建筑物的高度小于150m,上部楼层的侧向位移中也有相当部分是由于下部楼层的转角所引起的,此部分位移为刚体位移,而刚体位移并不产生结构内力”。而规范(包括国标《高规》和《抗规》)中给出的层间位移角限值,是“不扣除整体弯曲转角产生的侧移,即直接采用内力位移计算的位移输出值”的。遇到图1的极端情况,就会出现问题。

考虑结构整体弯曲的影响及其他影响因素(见广东省《高规》第3.7.3条条文说明),广东省《高规》放松了按弹性方法计算的结构层间位移角限值,其中框架结构放大了550/500=1.1倍,剪力墙结构则放大了1000/800=1.25倍,结构越高,整体弯曲造成的影响越大,相应的限值放松的越多。

当然,考虑重力二阶效应以后,整体转动后的结构会在自重作用下发生层间变形,此时楼板不再垂直于重力方向,重力在平行于楼板方向的分力Gsinθ充当了楼层侧向力的作用,如图2所示。

本质上,使得结构发生损伤的有害的层间位移应该是楼层在平行于楼板方向上的相对位移,规范采用楼层竖向构件最大的水平位移差计算层间位移Δ,具有一定的近似性。再考虑一个情况,如图3所示,某一状态下,结构顶点相对于底部节点的相对水平位移Δ=0,由此计算出来的结构整体位移角为0,但实际上结构各层已经发生了层间变形。当然对于某一层来说,一般不会出现这种情况。

图3(Figure 3)

层间位移角作为一个比较笼统的参数,严格来说,主要针对规则结构,也是过去计算条件有限的时候提出的一个控制参数,层间位移角的限值更是具有很多拍脑袋的成分,若单纯从控制结构损伤层面来说,在考虑了结构的几何非线性后,使用构件的应变、变形或损伤等参数可能更加直接和合理,以现在的计算手段这些都是可以实现。因此,在存在多种手段把控结构安全的情况下,适当放松层间位移角限值是可接受的。

今天小白学设计到此结束啦,喜欢的在上面点个赞吧!~~~ 8-)  8-)  欢迎批评指正!

  • PS. 这里讨论的主要是层间位移角对结构损伤控制方面的问题,层间位移角的大小还影响舒适度、非结构构件的损伤等,这是一个复杂的问题。
