某不规则钢框架结构设计与对比分析

摘要

结合某一有特色的不规则钢框架结构滑道,开展了2榀不等跨的二维钢框架设计.给出热轧圆钢管材料、截面选取及荷载统计.采用有限元软件ANSYS对结构的内力和变形进行了计算,并与相应规范进行对比,均满足规范要求.最后给出相应构造措施,为今后同类工程的设计提供参考.%In combination with a distinctive irregular steel frame structure slide, design of two kinds of unequal span two-dimensional steel frames are carried out, and hot rolled round steel pipe materials, section selecting and load statistics are given. Based on ANSYS finite element software internal force and deformation of structures are calculated, and compared with the corresponding norms, both meet the standard requirement. At last, corresponding structural measures are given, these can provide references for future similar engineering design.
