钢筋混凝土框架节点受剪承载力简化计算模型
Simplified model for shear bearing capacity of reinforced concrete frame joints
摘要
Abstract
The design formulas for the shear bearing capacity of reinforced concrete frame joints are semi-empirical based on experimental studies in current codes,resulting in the lack of a ＇theory＇ that can explain many different situations when the joint shear is involved.Based on previous studies,a simplified analytical model for the equivalent core of the frame joint under the combined action of axial load and shear was established.The shear bearing capacity of the equivalent joint core of test specimens was calculated using the equilibrium equation,geometric equation and physical equation.Furthermore,the suggested analytical model was verified using the data from 108 tests of beam-column joints（including ordinary interior joints,exterior joints,and joints with variable depth beams）.Good agreement between the experimental results and predicted results was achieved.In addition,study results indicate that the joint shear bearing capacity calculated by the suggested simplified model agrees well with that by the code method.Since the suggested simplified method has a more explicit mechanical basis,it can reasonable reveal the failure mechanism of the beam-to-column joint.关键词
