双层方钢管防屈曲支撑滞回性能试验研究

Jianzhu Gangjiegou Jinzhan
防屈曲支撑端部设计不合理，易形成薄弱部位破坏，为避免这种现象发生，提出了一种新型双层方钢管防屈曲支撑。双层方钢管约束着其间隙内的耗能板，耗能板上下部的正面或反面与内方钢管外表面或外方钢管内表面焊接，这种构造方式使得此类支撑受压、受拉时性能一致。设计并制作了4个双层方钢管防屈曲支撑试件，进行了低周反复荷载试验，研究了耗能板布置方式和耗能段数量对这种支撑性能的影响，得到了试件在循环荷载作用下的破坏机理、滞回性能、延性、刚度退化规律以及耗能能力等，并采用有限元软件进行了模拟分析。试验结果表明 ...

外接撑杆钢板剪力墙滞回性能试验研究

Jianzhu Gangjiegou Jinzhan
钢板剪力墙的拉力场对框架柱有不利的横向作用，易引发柱的提前破坏，并且墙板对框架梁的弯曲变形存在嵌固作用，使得塑性铰难以发展，不易实现“强柱弱梁”。针对这一问题，提出了一种外接撑杆钢板剪力墙结构，由撑杆、内框架和墙板组成。其中的内框架与墙板构成钢板剪力墙单元，通过撑杆与主框架相连后形成抗侧力结构。该结构利用钢板剪力墙单元的屈曲后拉力场提供主要的抗侧刚度和承载力，并通过撑杆将拉力场作用力直接传递至主框架梁柱节点，从而消除了其对框架柱的不利影响，同时避免了墙板对框架梁的嵌固作用 ...
