装配式钢板箍焊接栓筋连接框架柱试验研究
|
摘要
通过对4个足尺寸框架柱进行低周反复荷载试验,分别研究装配式钢板箍焊接栓筋连接框架柱在不同轴压比情况下的开裂破坏模式、滞回特性、延性、耗能性能、承载能力及刚度退化趋势。试验表明:在相同尺寸及配筋情况下,装配式钢板箍焊接栓筋连接框架柱比现浇框架柱的承载力偏高、延性性能偏差,其他抗震性能较为相当,钢板箍焊接栓筋连接方式安全可靠。
Seismic performance such as cracking form,hysteresis characteristic,ductility,energy dissipation,bearing capacity and stiffness degradation trend were separately discussed by 4 full size frame column in the condition of different axial compressive under low cyclic loading test.Experiments show that: in the same size and reinforcement case,the bearing capacity of assembling steel plate hoop-welding bolt reinforcement frame column was slightly higher than the whole concrete frame column,but slightly worse in ductility,other seismic performances was quiet.It was proved that the connection mode of steel plate hoop-welding bolt reinforcement was safe and reliable.
