不同构造措施的砌体填充墙框架结构抗震性能试验研究
|
摘要
为研究设置拉结钢筋、构造柱、水平系梁等不同构造措施的砌体填充墙对框架结构抗震性能的影响,进行了4榀不同构造措施的砌体填充墙框架结构模型和1榀纯框架结构模型在低周反复荷载作用下的对比试验,分析了各试件的破坏特征、滞回曲线、骨架曲线、位移延性、刚度退化、承载力退化和耗能性能等。结果表明:砌体填充墙有效地提高了框架结构的抗侧刚度和承载力,但具有不同构造措施的砌体填充墙框架结构的初始刚度和承载力基本相同;设置构造柱、水平系梁和同时设置构造柱和水平系梁的砌体填充墙框架结构的位移延性和耗能能力得到明显的改善,且其刚度退化较为缓慢。
In order to investigate the effects of masonry in-fill wall with different constructional measures including tie bar,constructional column,horizontal tie beam etc.on the seismic behavior of reinforced concrete frame structures,the comparison tests of four masonry in-filled reinforced concrete frame structure with different structural measures and one bare frame structure subjected to the low cycle reversed load were carried out.The failure mechanism,load-displacement hysteretic curves,skeleton curves,displacement ductility,rigidity degradation,bearing capacity degradation and energy dissipation were analyzed.The test results indicate that the masonry in-fill wall can effectively enhance the lateral stiffness and bearing capacity of frames,though the initial stiffness and bearing capacity of masonry in-filled reinforced concrete frame structure with different structural measures are basically the same.The displacement ductility and energy dissipation of the masonry in-filled reinforced concrete frame structure with constructional column or horizontal tie beam,constructional column and horizontal tie beam can be significantly improved with relatively low rate of rigidity degradation.
