双钢板组合剪力墙的初始变形和施工应力分析

Jianzhu Gangjiegou Jinzhan, 2016
双钢板组合剪力墙是一种新型抗侧力构件,它综合了钢板剪力墙和混凝土剪力墙的优点。较高的抗侧刚度、极限承载力、良好的延性和耗能能力使其具有广泛的工程前景。然而在实际施工过程中,通常将外侧钢板作为模板,连续多层浇筑混凝土。采用ABAQUS建立数值分析模型,研究了施工过程中的钢板平面外初始变形和钢板初始压应力对组合剪力墙抗震性能的影响。数值分析结果表明,钢板平面外初始变形和钢板初始压应力均会在一定程度上降低剪力墙的极限承载力和延性。最后给出了控制施工过程中钢板平面外初始变形和钢板初始压应力的建议。

带可替换剪切耗能梁段的防屈曲偏心支撑钢框架动力试验研究

Jianzhu Gangjiegou Jinzhan
可替换剪切耗能梁段作为与偏心支撑钢框架分离设计的独立耗能部件，不仅能在大震发生时将结构的塑性变形局限在耗能梁段区域内，更重要的是可以方便震后对结构的修复。文中制作了3榀该钢框架结构的缩尺模型，并对其进行了单向振动台试验，得到了结构的动力特性、塑性发展情况及破坏机理，并对模型的应力分布、位移响应、加速度响应等进行了分析研究。结果表明：该模型具备良好的耗能性能，剪切耗能梁段与防屈曲支撑构件分批耗能使得结构在地震作用下有较好的抗震性；带有可替换剪切耗能梁段的防屈曲偏心支撑钢框架构件的最大层间位移角符合规范要求，
