摘要
为了研究装配式混凝土墙体抗侧性能,文中结合试验测试及虚拟仿真的手段,分析了轴压比对装配式预制混凝土墙体承载力、刚度及能耗系数的影响.结果表明,所有轴压比下的骨架曲线均呈"S"形,随着轴压比的增加,骨架曲线后期出现下降;所有轴压比下,装配式混凝土墙体层间抗侧刚度均随着层间位移角的增大而呈现先快速降低后稳定的相关关系.相同位移角下,轴压比越大,层间抗侧刚度越大.能耗系数随着层间位移角的增加而先快速下降后维持稳定,轴压比对能耗系数与层间位移角的影响无明显规律.
Abstract
In order to study the lateral resistance of prefabricated precast concrete walls,the effects of axial compression ratio on the bearing capacity,stiffness and energy consumption coefficient of prefabricated precast concrete walls were analyzed by means of test and virtual simulation.The results show that the skeleton curves are S-shaped under all axial compression ratios.With the increase of axial compression ratio,the skeleton curve appears a decreasing stage in the later stage.The lateral stiffness of prefabricated precast concrete walls with axial compression ratio decreases rapidly at first and then becomes stable with the increase of displacement Angle.Under the same displacement Angle,the greater the axial compression ratio is,the greater the lateral stiffness is.With the increase of the interlayer displacement Angle,the energy consumption coefficient decreases rapidly at first and then remains stable.The axial compression ratio has no obvious effect on the energy consumption coefficient and the evolution law of the interlayer displacement Angle.
