[书]PERFORM-3D原理与实例 – 第 16 章 – Pushover 分析原理与实例

[Book] PERFORM-3D Theory and Tutorials – Chapter 16 – Pushover Analysis Theory and Tutorial


  • 章节内容简介 [ Chapter Content Abstract ]

Pushover 分析方法又称为静力弹塑性分析方法或静力非线性分析方法,是一种以结构顶部的侧向位移作为整体抗震性能判据的结构抗震性能评估方法,它将非线性静力分析与反应谱理论紧密结合起来,用静力分析的方法预测结构在地震作用下的动力反应和抗震性能,在基于性能的抗震设计中得到了较为广泛的研究与应用。我国的《高层建筑混凝土结构技术规程》(JGJ 3-2010)第3.11.4条明确指出[1],高度不超过150m的高层建筑可采用静力弹塑性分析方法进行结构的抗震性能评估。

通过Pushover分析进行结构抗震性能评估的基本步骤如下[2]

(1)建立结构的Pushover曲线;

(2)确定用于评估的地震动水准;

(3)选择用于评估的性能水准及其容许准则;

(4)采用特定的方法求取结构性能点并进行结构性能评估。

常用的Pushover分析方法主要包括ATC-40[3]采用的“能力谱法”、FEMA 356[4]推荐的“目标位移法”、FEMA 440[5]提出的“等效线性化”和“位移修正”两种方法等。其中能力谱法是最早提出的Pushover分析方法,本章主要介绍能力谱法的基本原理及其在PERFORM-3D[6,7]中的应用。

[书]PERFORM-3D原理与实例 – 第 15 章 – 多点激励地震分析

[Book] PERFORM-3D Theory and Tutorials – Chapter 15 – Multi-support Seismic Excitations


  • 章节内容简介 [ Chapter Content Abstract ]

地震动以波的形式向四周传播,在传播的过程中,不仅有时间上的变化特性,也存在空间变化特性。地震动的空间变化特性主要表现为以下几个方面[1]:(1)行波效应,指的是由于地震波的传播速度有限,当结构支承点间距较大时,地震波到达各支承点的时间存在一定的差异;(2)部分相干效应,指地震波在传播的过程中产生复杂的反射和散射,同时由于地震动场不同位置的地震波叠加方式不同而导致的相干函数损失;(3)衰减效应,地震波在传播的过程中,随着能量的耗散,其振幅将会逐渐减小;(4)局部场地效应,指的是由于地震动场的不同位置土的性质存在差异,导致地震波的振幅和频率也存在差异。这几种效应都会导致结构不同支承点处输入的地面运动存在差异,从结构分析的角度来说都是一致的,统称为多点激励效应或非一致激励效应。

PERFORM-3D[2, 3]中不存在针对多点激励的地震分析工况,但可利用PERFORM-3D中的动力荷载工况(Dynamic Force Load Case)加支座弹簧单元(Support Spring)实现多点激励地震分析。本章对此方法进行介绍,并通过具体算例讲解该方法的应用和可行性。

  • FEMA 440等效线性化方法介绍 ( Introduction of FEMA 440 Equivalent Linearization Method )

FEMA 440等效线性化方法是众多Pushover分析方法中的一种,是ATC-40能力谱法(Capacity-Spectrum Method )的一种改进,其基本原理如下图所示。( Equivalent linearization procedure of FEMA 440  is a modification to the Capacity-Spectrum Method (CSM) of ATC-40. )

When equivalent linearization is used as a part of a nonlinear static procedure that models the nonlinear response of a building with a SDOF oscillator, the objective is to estimate the maximum displacement response of the nonlinear system with an “equivalent” linear system using an effective period, Teff, and effective damping, βeff (see Figure above). The global force-deformation relationship shown in the above figure for a SDOF oscillator in acceleration-displacement response spectrum (ADRS) format is termed a capacity curve. The capacity curve shown in the above figure is developed using the conventional procedures of FEMA 356 or ATC-40. The effective linear parameters are functions of the characteristics of the capacity curve, the corresponding initial period and damping, and the ductility demand, µ

采用Abaqus的Standard求解器做个弹性框架结构的地震时程分析小例子,框架模型取用前面博文《Modal analysis of a frame using Abaqus (Abaqus框架模态分析)》模态分析中的框架结构,如下图所示。

时程分析暂不讨论阻尼的作用,不考虑框架荷载和重力,输入单向地震波如下图所示,其中地震波按基底加速度进行输入。

提取Abaqus的顶点的位移时程结果,并与ETABS和SAP2000的分析结果进行对比。

与SAP2000对比结果:

与ETABS对比结果:

由以上的对比结果可见:ABAQUS和SAP2000的分析结果几乎没差异,ABAQUS和ETABS的分析结果在前20S吻合较好,后20s有些许差异。造成这个现象的主要原因是,ABAQUS和SAP2000分析时均采用的是基于Hilber-Hughes-Taylor(HHT)的直接积分方法, 而ETABS采用的模态时程分析方法。 :-)  :-)  :-)
