轴压比对带PC填充墙的装配式联肢剪力墙受力性能影响分析
装配式联肢剪力墙 受力性能 数值模拟 轴压比
2021/4/13
在试验研究的基础上，对带预制混凝土(PC)填充墙的装配式联肢剪力墙进行数值模拟分析，系统研究不同连接方式、轴压比下结构的破坏形态、承载力、刚度、延性等性能。结果表明：PC填充墙的存在可提高结构的承载力、抗侧刚度，刚性连接时结构的周期折减系数建议取0.8～1。随着轴压比的增大，试件的屈服荷载和峰值荷载增大；轴压比小于0.3时，结构的抗侧刚度随轴压比的增大而增大，当轴压比大于0.3时，随轴压比增大，刚...
针对钢绞线锈蚀导致黏结性能下降造成预应力混凝土(PC)梁抗弯承载弯矩下降的问题，引入锈蚀影响因子研究锈蚀对预应力筋强度利用的影响，基于锈蚀PC梁静载试验，给出预应力筋强度利用率与锈蚀率的关系，进而建立锈蚀PC梁抗弯承载弯矩计算模型并进行验证。研究结果表明：PC梁抗弯承载弯矩随钢绞线锈蚀的增大而降低；在极限状态下，钢绞线屈服与配筋率和锈蚀程度有关，当配筋率小于0.23时，无论锈蚀与否，钢绞线均会屈服...
