部分预制装配型钢混凝土梁受剪性能试验研究
Experimental study on shear performance of partially precast steel reinforced concrete beams
摘要
Abstract
In order to investigate the shear performance of partially precast steel reinforced concrete (PPSRC) beams and partially precast castellated steel reinforced concrete (CPSRC) beams,static tests of 15 PPSRC specimens and 2 cast-in-place control specimens were carried out on the hogging-moment and the sagging-moment regions.The failure modes and bearing capacities were thoroughly examined based on the results of the failure process,and the strain of stirrup as well as the shear force-rotation relationship.Based on the test results,the main factors governing the mechanical behavior of the PPSRC beams were carefully analyzed.It is showed that the shear capacity of the PPSRC beam is affected by the strength of cast-in-place concrete,the shear span ratio and the type of steel.The precast outpart of the PPSRC beam is well bonded to the cast-in-place inner part,and the partially precast steel reinforced concrete beams show good performance,meanwhile partially precast beams exhibit similar shear performance to the cast-in-place SRC control group.关键词
