装配式隔震节点的试验研究与分析
|
摘要
提出一种适用于装配式钢筋混凝土隔震结构的新型装配式隔震梁柱节点,对两尺寸和配筋完全相同的现浇式节点和装配式节点进行了低周反复荷载作用下的试验对比研究.基于ABAQUS有限元分析软件对试件建立了精细化有限元分析模型,对比了试验数据和有限元分析结果.结果表明,装配式隔震节点具有跟现浇节点相近的抗震性能.
This paper puts forward a newly-assembled seismic isolation connection,which is suitable for assembled concrete structure. Low cyclic loading tests of assembled connection( PCB) and cast-in-place connection( MCB) are conducted and compared. Refined finite element models of test specimens are built and analyzed within environment of ABAQUS. Both the analytical work and test results show that assembled concrete connection can have the similar seismic performance to cast-in-place connection.
