【摘要】 通过对1榀4层单跨内填砌体短肢墙结构在低周反复荷载作用下的拟静力试验研究,分析了这类结构的延性、滞回特性、骨架曲线及刚度退化等问题。研究表明:砌体的存在大幅提高了结构的初始刚度和极限承载力。内填砌体短肢墙结构具有双功能结构的优点,是一种新型抗震控制剪力墙。根据试验中发现的问题,为工程设计提出了建议。更多还原

【Abstract】 A static test for one 4-story composite structure of short-limb shear with the masonry filler wall is conducted under low-cyclic loading.Based on the experimental results,the bearing capacity,deterioration process of stiffness,ductility,hysteretic curves,energy dissipation and failure characters are analyzed.The analysis results show that the values of initial stiffness,yielding load and ultimate bearing capacity have been improved obviously.The short-limb shear with the masonry filler wall has the advantage of dual function structure,which is a new aseismic shear wall.Some suggestions for engineering design are also presented in this paper.更多还原
