【摘要】 周期折减系数对结构的地震作用有明显影响,但目前只有已经淘汰的实心砖填充墙的取值,没有加气混凝土砌块、混凝土空心砌块和粘土砖空心砌块填充墙的取值。通过计算得出各类墙体的刚度和实心砖墙刚度的比值,根据填充墙刚度和结构自振周期的关系,给出了各类墙体的周期折减系数,可供工程设计参考。更多还原

【Abstract】 Period shortening factor influences remarkably on seismic loading of structure,there is none number but fired common brick infilled wall,and lacks of numbers for antoclaved aerated concrete blocks infilled wall、 concrete small hollow blocks infilled wall and fired clay hollow blocks infilled wall.this paper computes the stiffness ratio of fired common brick infilled wall to other infilled wall,according to the relation of the infilled wall stiffness and natural period of vibration,and gives period shortening factor of several types infilled wall.更多还原
