Abstract

Strong columns and weak beams and "strong joints and weak members" are important concepts in the design of reinforced concrete ductile frame structures. However, many earthquake damages show that a large number of reinforced concrete frame structures still do not guarantee the realization of the above seismic concepts. In order to solve this problem, this paper designs and manufactures a beam column joint with plate, which includes the bottom column base and the moment increasing coefficient of the column end is 1.2. Through the quasi-static reciprocating loading test, the influence of the bearing capacity, ultimate deformation, stiffness degradation and hysteretic energy consumption of the specimen is investigated. The test results show that when the moment increasing factor at the end of the column is 1.2, the failure order of the specimen is bottom column base beam slab bottom column base, the plastic hinge occurs at the bottom of the column, and the position of the column in the beam column joint is not damaged; According to the seismic code, the overall failure mode of the beam column joints with slab and infilled wall at the bottom column base can be "strong column and weak beam" and "strong joint and weak member" under the action of reciprocating quasi-static loading.
