不同轴压比下的自密实混凝土加固框架节点抗震性能试验研究
Experimental study on seismic performance of frame joints strengthened by self-compacting concrete considering the influence of interface treatment
摘要
Abstract
Three frame joints were produced strengthened by self - compacting concrete. Take MTS servo loading system of static test for the frame joints, to study the influence of different axial compression ratio for the seismic performance. The axial compression ratio of the three strengthened specimen were respectively 0. 1 , 0. 3, 0. 5. The results of the damage process, strain of the old steel and new steel, the load - displacement hysteresis loops were analyzed, and it was found that with the axial compression ratio of column end increasing, the constraint of the joint core by the column pressure is gradually increasing, and the shear capacity, energy dissipation capacity, structural stiffness, and ultimate displacement of the strengthened joints increased, while the displacement and the displacement ductility factor decreased.关键词
