全装配式钢筋混凝土框架-剪力墙结构抗震性能试验研究
Experimental study on seismic behavior of wholly precast RC frame-shear wall structure
摘要
Abstract
Two geometrically identical half-scale RC shear wall-frame structure specimens were constructed and tested under quasi-static reversed cyclic lateral loading to study the seismic behaviors of the RC shear-wall frame structure,such as its failure mechanism,failure mode,plastic hinge development,hysteretic response,displacement ductility,stiffness degradation and energy dissipation capacities.One unit was a conventionally cast-in-situ concrete shear wallframe structure specimen named RCFW,and the other unit was a precast one named PCFW2 erected with fabricated shear walls and frame components.The test results show that specimen PCFW2 has approximately equal cracking load,similar failure process and final failure mode to specimen RCFW.Two kinds of rebar connecting methods,rebar splicing by grout sleeve and rebar lapping in grout-filled hole,can transfer the rebar stress effectively.Specimen PCFW2 shows good integrity.The seismic characteristic values such as yield load,peak load,and ultimate load of specimen PCFW2 are less than those of RCFW,where the difference is approximately 13.0％.The displacement ductility coefficient of specimen PCFW2 is also less than that of RCFW.The test results also show that the energy dissipation capacity of PCFW2 is greater than that of RCFW at the most loading stage during the whole loading process.The edge columns of the shear walls in the wholly precast RC frame-shear wall structure is proposed to be connected with rebar splicing by grout sleeves,and the rest part of the shear walls with rebar lapping in grout-filled holes.Microexpansive concrete is proposed to be used in the wet joints of the frame parts as cast-in-place concrete.关键词
