摘要
本文通过对17个浮石混凝土砌块墙片的恢复力特性试验,评价了这种墙体的抗震性能,给出了砌块墙片的抗震强度计算公式、恢复力简化横型以及骨架曲线的刚度退化表达式,讨论了试件的宽高比(b/h)及竖向压应力(σ_0)对试件抗震能力的影响.
Through analysis on the test results of 17 shear walls and basic mechanicalproperty specimens of hollow brick masonry,the paper makes an evaluation on theseismic performance of hollow brick masonry walls,and also puts forward the for-mulae of calculating the shear strength,and unloading rigidity of hollow brick ma-sonry walls.The paper also alalyses the influences of b/h(width to height ratio ofwalls)and σ_0(vertical compressive stress of walls)on the seismic behavior of hol-low brick masonry walls.
