Design,analysis And Application Of Assembled Reinforced Concrete Beam Column Joint

Assembly architecture includes assembled steel structure and assembled reinforced concrete structure.This paper studies the assembly type reinforced concrete structure.Based on the existing cast-in-place reinforced concrete beam column joints,the precast reinforced concrete beam column joints are designed according to the newly issued technical specification for fabricated concrete structures,JGJ1-2014,and new joints are designed.The main research contents are as follows: the main research contents are as follows: the comparison of the force performance of the assembled reinforced concrete beam column joint and the equivalent reinforcement ratio of the cast-in-place joints:Firstly,by reading a lot of literature to the finite element model for the selection of the existing literature,in the same reinforcement ratio of the cast-in-place reinforced concrete beam column joints and the design of the precast reinforced concrete beam column joint development modeling using ABAQUS software,adjust the various numerical parameters,to ensure that each parameter coefficients are the same,thus ensuring convergence two modelsSecondly,the calculation and analysis of the static analysis and dynamics are carried out.Through force analysis,we get the data of stress change,displacement change and displacement under low cyclic loading under the same axial load,lateral load,axial and lateral combined load and low cyclic load.The results show that: the development of prefabricated reinforced concrete beam column joints designed with cast-in-situ displacement under the same static and dynamic change,should be the basic trend of change,low cyclic load displacement changes,the maximum displacement is basically the same,the largest steel yield strength are basically the same.It shows that the new type of reinforced concrete beam column joints designed in this paper have good mechanical performance and have practical application value.
