Xtract CAD复杂截面建模小工具
Xtract 是一个非常好的截面分析程序,如果支持国产也可以使用Dino开发DinoSec快速截面分析程序。Xtract更适合于建立非常复杂的组合截面,如果建立复杂截面,推荐使用该项程序,该程序是CAD为基础,建立复杂的构件截面,包括巨型柱及复杂的桥梁截面,该程序需要使用AUTOCAD2013版程序,程序请自行下载。

DINOSEC截面分析程序使用手册
1)程序介绍:
DINOSEC截面分析程序是基于平截面假定,对常用组合截面进行承载力的计算,通过计算得到主轴的PMM曲线或指定轴力的Mx-My相关曲线,PMM曲线对构件的承载力设计具有指导意义。DINOSEC的输入与输出十分便利,可快速用于工程设计。 计算主要原理如下:
(1)采用平截面假定,应变分布为平面方程。
(2)截面分析采用纤维单元法,即将混凝土与钢材离散为纤维。
(3)迭代分析采用二分法逼近求解。
(4)通过洞口(负应力)纤维考虑纤维重叠的影响,如叠合柱的计算中已考虑

Numerical Analysis of Cyclic Loading Test of Shear Walls based on OpenSEES
Han Xiaolei Chen Xuewei Jack CHEANG Mao Guiniu Wu Peifeng

ABSTRACT :
Neither the original structure nor the altered structure of the Garden Hotel in Guangzhou accords with the ductile details of seismic design based on current Chinese codes. In order to explore the seismic performance of the original shear wall structure and the altered shear wall structure, the cyclic loading testes of the shear walls with different reinforcement ratio and constructional details are carried out. This paper presents the numerical analysis of the cyclic loading testes of shear walls with SWNA (Shear Wall Nonlinear Analysis) program. SWNA program is secondary developed based on OpenSEES and MVLEM. Compare with the testes, the numerical results confirmed the accuracy of this analysis procedure in representing the nonlinear behavior of the shear wall, such as the shifting of natural axis, shear deformation, local collapse and collapse mechanism. The analysis procedure based on MVLEM, which saves the calculating cost due to fewer DOFs, can stimulate the nonlinear behavior of the shear wall, and fit for global inelastic analysis and performance based design of tall building structure.

采用命令去进行迭代收敛的判断,再改算法,这个命令流在官方的教程中有所体现。
