企口现浇装配预制梁承载力试验研究
Experimental study on cast-in-place concrete of prefabrication and assembly beam
摘要
Abstract
Three same size assembly precast beam with cast-in-place groove and one general integral beam were used to test the groove and bearing capacity.Through investigating the mechanical parameters,deoxidation ability and modification ability,the stress of groove and change law of local stiffness were identified.The results show that cast-in-place groove has little effect on bearing capacity of assembly precast beam,deformability meets the design specifications requirement,the congruent position of bending moment in maxima is the worst for junction.The local stiffness of cast-in-place groove decreases fast at the beginning of loading.关键词
