Jianzhu Gangjiegou Jinzhan, 2009 本文先建立四个有初始几何缺陷的框架结构,通过有限元分析分别得到这四个框架的竖向极限荷载Pcr和水平极限荷载Hcr;再对与这四个框架几何及截面相同但没有初始缺陷的框架,用之前计算得到竖向和水平极限荷载分别按一阶弹性分析和二阶弹性分析得到其内力,用我国现行《钢结构设计规范》(GB50017)中压弯杆件极限承载力验算式计算其名义应力,并与实际结果比较。结果证明,进行钢框架压弯杆件平面内稳定验算时,对框架采用二阶弹性分析,并将柱的计算长度取为实际柱长,所得验算结果较对框架采用一阶弹性分析 ...

Jianzhu Gangjiegou Jinzhan, 2015 为了研究不同墙体连接构造下高层建筑钢结构的抗震性能,进行了蒸压轻质加气混凝土(ALC)条板或砌块填充钢管混凝土框架结构的低周反复加载试验。根据填充墙施工安装工艺、钢结构特点和墙板类型,介绍了大板、条板和砌块等轻质墙体与钢框架的连接构造。通过试验研究了U形钢卡、钩头螺栓、摇摆连接件和角钢等连接构造对墙板抗震性能的影响。试验研究表明,在地震作用下,用U形钢卡或角钢内嵌与摇摆件外挂ALC条板的钢管混凝土框架结构具有良好的耗能能力;采用U形钢卡、钩头螺栓、摇摆件和角钢等合理构造措施 ...
