Abstract:There is a certain market demand for the construction plan of weak connection floor, but the existing codes have no corresponding calculation and measures for this kind of structure, and special research is necessary. The minimum thickness of the floor slab with weak connection was determined by shear checking formula for beam and wall based on code, so that the floor section of the site can satisfy the performance target of shear elasticity of rare earthquake. Through comparative analysis, the flexural stiffness and axial stiffness of the beam with weak connections are critical to the coordination of the various branches. Measures should be taken to ensure the stiffness of the beam to prevent the progressive collapse of the structure. Set the beam of the weak joint to meet the performance goal of flexural elasticity under moderate earthquake. Manually check the beam without full-section cracking under moderate earthquake, and strengthening the anchoring conditions of the beam, etc. The safety of the weak connection structure can be ensured.
Keywords:weak connection; design method; shearing resistance; stiffness; cooperative work
