EXPERIMENTAL INVESTIGATION AND NONLINEAR ANALYSIS OF ABNORMAL INTERIOR JOINTS IN RC FRAME STRUCTURES

摘要：

The experiments on five plane abnormal interior joints and one space abnormal joint of reinforced concrete frame were performed. Work mechanism and seismic behavior of abnormal joints were put into analysis in this paper. Load-displacement curves of RC frame abnormal joints under monotonic load were simulated with ANSYS finite element program, and the shear strength, failure modes and stress distribution for steel bar&concrete in abnormal joints were researched. Based on the results of nonlinear analysis and experimental study, two typical failure modes were presented: minor core (determined by the low beam and the top column) shear failure and column shear failure. It can be served as reference for design of abnormal joints.
