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。

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

Research On The Seismic Design Of Transfer-Storey Structures Based On Philosophy Of Capacity Design Under Severe Earthquake
Jack CHEANG Han Xiaolei  Tang JianQiu   Chen Xuewei

ABSTRACT :
Both theoretical analysis and engineering applications of the transfer-storey structures are mostly limited in elastic stage under frequent earthquakes; the structural behavior after yielding under severe earthquake need to be studied by elastic-plastic analysis. And there is no specific and quantitative method to ensure that transfer structures can “resist severe earthquake without collapse”.  In this paper, the philosophy of capacity design is introduced into the design of transfer-storey structures and a practical design method for transfer structures under severe earthquake is presented. Through push-over analysis, various limit states of coupled shear walls are disclosed. Parameters that influence significantly the structure behavior such as integer coefficient of coupled shear walls, reinforcement ratio of coupling beams and height-width ratio of shear walls are highlighted. The shear overstrength of the coupling beams under the ideal limit state is reduced with reduction coefficient K. Overstrength of shear walls is derived by ultimate state analysis, which considers the axial forces increment of shear walls caused by shear overstrength of coupling beams. On this basis, mechanical characteristics and capacity based seismic design method of transfer storey under severe earthquake are studied by elastic-plastic analysis. A series of nonlinear dynamic time-history analysis has been completed, which considers the influence of varied parameters including the stiffness and mass of transfer structures, seismic protected intensity and the position of transfer storey. Moreover, the simplified formulas and the detail procedure for capacity design of transfer structures are presented.

KEYWORDS: philosophy of capacity design, design of transfer-storey, structural overstrength, push-over analysis, nonlinear dynamic time-history analysis, severe earthquake
