[Tool] OpenSees Fiber Section Viewer [工具][OpenSees纤维截面可视化工具]

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。

[书]PERFORM-3D原理与实例 – 第5章 – 纤维截面模型

梁柱纤维截面模型的具体思路是将单元内部积分点处的截面离散为若干纤维,并假定截面满足平截面假定,由截面的曲率和中性轴的位置获得纤维应变,由纤维应变结合所采用的材料滞回本构关系获得纤维的应力,将纤维的应力沿截面积分可以获得截面的轴力和弯矩。纤维截面模型通过材料积分获得截面的内力-变形关系,与塑性铰模型直接给出截面内力-变形关系相比,在描述截面压弯耦合非线性行为方面有着更大的优势。本章将对PERFORM-3D[1,2]中的梁、柱纤维截面模型进行介绍。
