Abstract:In order to study the feasibility of the vertical distribution reinforced bar lapping connection method of core-grouted prefabricated concrete shear walls, 16 precast concrete reinforced bar lapping connection components were designed and made with the 100% area percentage rate of the lap joints. The reinforced bar lapping length was determined according to code for design of concrete structures. Considering influential factors of reinforced bar diameter and lapping length, uniaxial tension tests on specimens were completed to obtain the failure mode and the impact laws of various factors. The experimental study shows that, the lapping length calculated by formula of reinforced bars lapping length in the code for design of concrete structures meets the design requirements. This connection method is reliable in performance and its construction is convenient, and it is suitable for the reinforced bar connection of concrete components of prefabricated concrete structure.

Keywords:assembled monolithic structure；  shear-wall structure；  lapping length; housing industrialization
