摘要
考虑单层平面索网支承与幕墙玻璃之间的协同工作,建立结构体系的有限元模型,对有限元模型进行瞬态动力分析.通过有限元程序对索网幕墙体系中的钢索直径、钢索预拉力、幕墙玻璃网格尺寸、玻璃厚度对其动力性能的影响进行了研究,得到该幕墙结构在地震动力作用下的动力特性.研究表明,单层索网幕墙结构体系响应具有较强的非线性,钢索预拉力、幕墙玻璃网格及其厚度对结构动力性能影响较大.此外,结构体系刚度与幕墙玻璃密切相关.
Coordination of single-layer plan cable net and glass panels was considered.The finite element model was established and analyzed with the transient dynamic.Based on finite element methods,the effect of dynamic characteristics of glass curtain wall were studied,in which the main parameters considered are cable diameter,cable pre-stress,glass mesh and glass thickness.The dynamic characteristics of glass curtain wall under earthquake load were obtained.The results show that the response of glass curtain wall supported by monolayer cable net belongs to nonlinear system in which some factors have great influences on the dynamic characteristics of system,such as cable pre-stress,glass mesh and glass thickness.Besides,structural system stiffness is closely related with the glass panel.
