预应力型钢混凝土框架结构竖向反复荷载作用下抗震性能试验研究OA北大核心CSCDCSTPCD
Experimental study on seismic performance of prestressed steel reinforced concrete frame structure under vertical reversed loading
通过对1榀柱中内置型钢和1榀梁柱均内置型钢的预应力型钢混凝土框架的竖向反复荷载试验,研究预应力型钢混凝土框架的破坏机制、滞回特性、延性、刚度和耗能等性能.结果表明:预应力型钢混凝土框架梁是梁铰破坏机制,极限状态时“拱效应”提高了框架梁的承载能力；预应力型钢混凝土框架梁滞回曲线饱满,变形恢复能力小于普通预应力混凝土框架梁；预应力型钢混凝土框架梁位移延性系数均值为4.8,普通预应力混凝土框架梁的为4.18,均有较好的延性；等效黏滞阻尼系数介于0.25…查看全部>>
A study was conducted on the vertical seismic behaviors of one prestressed steel reinforced concrete frame with steel in columns only and one frame with steel in beams and columns.The seismic behavior of prestressed steel reinforced concrete frames,such as the failure patterns,hysteresis loops,displacement ductility,stiffness and energy dissipation was studied.It is shown that the failure patterns are beam hinge failure and arching action can enhance the ult…查看全部>>
