自密实轻骨料混凝土框架抗震性能试验研究
|
摘要
为了研究自密实轻骨料混凝土框架的抗震性能,确保其在抗震地区应用的安全性,采用手动液压双向千斤顶对自密实轻骨料混凝土框架进行了水平低周反复荷载作用下的拟静力试验.在试验过程中观测了自密实轻骨料混凝土框架的裂缝开展情况,破坏情况等.重点研究了自密实轻骨料混凝土框架的承载能力、延性、耗能能力、刚度退化等性能,并和普通混凝土框架的相关性能进行了对比分析,对自密实轻骨料混凝土框架结构抗震性能的分析研究可为自密实轻骨料混凝土框架结构的工程设计提供一定的设计参考.
In order to guarantee the safety of self-compacting lightweight aggregate concrete frame in earthquake,experiments of self-compacting lightweight aggregate concrete frame under low-cyclic horizontal and constant vertical loads are performed.The manual bi-directional hydraulic jack is used to put the frame under quasi-static loads.Crack developing,failure process,and strains of steel bars and concrete,etc.are investigated for self-compacting lightweight aggregate concrete.Self-compacting lightweight aggregate concrete frame are emphatically studied on the bearing capacity,ductility,energy dissipation,stiffness degradation performance and so on.A comparison of such behavior is made with that of the ordinary concrete frame.Suggestions on engineering application of self-compacting lightweight aggregate concrete frame are made following the analysis of the earthquake resistance behavior of self-compacting lightweight aggregate concrete frame.
