搭载反应釜的钢框架结构动力性能分析与设计建议
反应釜工作时会对搭载其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的设计主要采用静力方法,忽略了反应釜运转对其的影响。提出了一种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。基于现行标准《容器支座 第4部分:支承式支座》(NB/T 47065.4—2018),分析了反应釜支座底部节点与整体框架的承载能力,以及不同反应釜搅拌叶片旋转方向下的动力响应,并进行了该类结构的优化设计研究。结果表明:按现行标准设计的反应釜支座与连接节点为结构的薄弱部位,而基于钢材<italic>S</italic>-<ita...
