[工具][软件]OSFSV v2021: OpenSees Fiber Section Viewer [OpenSees纤维截面可视化工具]

实干、实践、积累、思考、创新。


一直想更新这个软件,这款软件最早在2017年开发出来的时候,算是全网唯一的opensees的纤维截面工具,最近终于可以抽时间进一步对这个软件进行更新。

  • 程序图标 ( Program Icon )

  • 程序介绍 ( Program Introduction)

OpenSees纤维截面可视化工具 (OpenSees Fiber Section Viewer)。程序基本功能是,解析OpenSees的.tcl文件,提取其中的纤维截面,显示具体的纤维截面剖分情况。OpenSees Fiber Section Viewer is a visualization program for fiber secion in OpenSees.

编写这个程序的主要目的是,由于很多.tcl文件编写时,纤维截面的定义采用的是 OpenSees 提供的path和layer命令,这些命令容易编写却不方便查看,难以检查具体的纤维截面剖分是否正确。尤其是在阅读别人编写的 .tcl 文件时,由于编写命令的习惯不同,更加难以检查 纤维截面的定义是否合理。因此,如果有一个程序能将OpenSees的fiber、path和layer命令解析出来,并形成纤维图形直观显示,将大大提高初学者阅读和检查.tcl文件的效率,本博文提供的这个小程序很好的解决了这个问题。The main purpose of writing this program is that when many .tcl files are written, the definition of fiber cross-section uses the path and layer commands provided by OpenSees. These commands are easy to write but inconvenient to view, and it is difficult to check whether the specific fiber cross-section is correct. . Especially when reading .tcl files written by others, it is more difficult to check whether the definition of fiber cross-section is reasonable due to the different habit of writing commands. Therefore, if there is a program that can parse the fiber, path and layer commands of OpenSees and form a visual display of fiber graphics, it will greatly improve the efficiency of beginners reading and checking .tcl files. This small program provided in this blog post is very good. solved this problem.

旧版的纤维截面可以在这个连接查看:http://www.jdcui.com/?p=5007

新版软件主要做了一下更新:

(1)OpenSees的TCL模型文件中文路径已经支持。

(2)修正了旧版软件部分截面提示“sqrt: DOMAIN error”错误无法进行截面显示的问题

(3)增加了纤维截面图形窗口的交互操作:平移,缩放等

(4)增加了错误提示窗口,若截面某部分定义出错,软件可在错误提示窗口中提示,使用者可根据提示检查相应的纤维截面定义命令。

(5)对于部分纤维定义错误的部分,如果纤维坐标没问题,会在图形中以交叉的方式显示,使用者可很清楚检查哪部分命令是错误的。

  • OpenSees中的纤维截面命令 ( Fiber Section Command in OpenSees )

OpenSees中的纤维截面如下所示,摘自 http://opensees.berkeley.edu/wiki/index.php/Fiber_Section

This commnand allows the user to construct a FiberSection object. Each FiberSection object is composed of Fibers, with each fiber containing a UniaxialMaterial, an area and a location (y,z). The command to generate FiberSection object contains in { } the commands to generate all the fibers in the object. To construct a FiberSection and populate it, the following command is used:

section Fiber $secTag <-GJ $GJ> {
fiber…
patch…
layer…

}

$secTag      unique tag among sections
$GJ              linear-elastic torsional stiffness assigned to the section (optional, default = no torsional stiffness)
fiber…        command to generate a single fiber
patch…       command to generate a number of fibers over a geometric cross-section
layer…        command to generate a row of fibers along a geometric-arc

NOTES:

The command to generate a FiberSection contains in { } the commands to generate all the fibers in the section.
The patch and layer commands can be used to generate multiple fibers in a single command.
In an element recorder you can ask a FiberSection for its ‘deformations’, ‘forces’, ‘forceAndDeformation’, ‘fiber $fiberNum $matArg1 ..’, ‘fiber $yLoc $zLoc $matTag $matArg1 ‘

——— from http://opensees.berkeley.edu/wiki/index.php/Fiber_Section

纤维截面的定义主要有三个命令: fiber, path和layer。OpenSees纤维截面可视化工具可支持对这三种命令进行解析。

fiber 命令:

patch 命令:

layer 命令:
