部分预制装配型钢混凝土梁受弯性能试验研究
Experimental study of partially precast steel reinforced concrete beams under positive bending
摘要
Abstract
In order to bring out the potentials in mechanical and constructional performance of steel reinforced concrete structures and prefabricated structures,two kinds of partially precast steel reinforced concrete beams,which are abbreviated here as PPSRC (partially precast steel reinforced concrete) beam and HPSRC (hollow partially precast steel reinforced concrete) beam,were presented in this paper.With the aim to investigate the flexural behaviors,failure modes and flexural capacities of the PPSRC and HPSRC beams,static loading tests on seven T-beam specimens were carried out.The effects of prefabricated construction method,section shape and strength of cast-in-place concrete were critically examined.The results indicate that the HPSRC and PPSRC beams exhibit similar behaviors and failure modes,and the flexural performance are seldom affected by prefabricated construction method and section shape.Meanwhile,the flexural capacities of both PPSRC beams and HPSRC beams increase with the increasing of strength of cast-in-place concrete.Finally,corresponding sectional flexural capacity analyses are conducted,and the results obtained from the formulas agree well with those from the experiments.关键词
