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文中提出了一种钢网格支撑钢框架结构，分析了该结构在单调荷载与循环荷载作用下的力学性能。结果表明：单调荷载作用下，钢网格支撑钢框架的承载力较人字形支撑钢框架的承载力提升约50%，初始刚度显著提高；循环荷载作用下，该结构滞回曲线更饱满，耗能系数更高。结构层间位移角小于1/50时，钢梁与支撑连接处的竖向位移较小，最大值为11.35 mm，支撑未发生平面外失稳；层间位移角大于1/50时，钢梁与支撑连接处的竖向位移快速增大。参数分析表明：圆筒节点的肋板高度与厚度对钢网格支撑钢框架的单调加载承载力、滞回承载力 ...

Jianzhu Gangjiegou Jinzhan反应釜工作时会对搭载反应釜的钢框架施加较大的高频动荷载，但是目前此类钢框架结构主要还是采用静力方法进行设计，忽略了反应釜运转对其的影响。提出了一种采用质量点和梁单元结合的模拟反应釜动力体系及其与钢框架连接的简化方法，可高效获得反应釜运转时钢框架的动力响应。分析了基于现行标准《容器支座 第4部分：支承式支座》（NB/T 47065.4—2018）设计的反应釜支座底部节点与整体框架承载能力以及反应釜搅拌叶片旋转方向不同情况下的动力响应，并进行了该类结构的优化设计研究。结果表明 ...
