钢筋混凝土双肢柱拉肢破坏机理及斜截面承载力分析

以钢筋混凝土双肢柱拉肢为研究对象 ,根据 4种剪跨比、5种配筋、3种配箍及不同轴拉比及变动轴拉、压力作用下共 36个试件进行的试验结果 ,就其破坏机理及不同因素对拉肢斜截面承载能力的影响进行了对比分析 ,在统计分析及合理简化的基础上提出了双肢柱拉肢斜截面承载能力的实用计算方法。

FAILURE MECHANISM AND INCLINED-SECTION BEARING CAPACITY ANALYSIS OF THE TENSILE LEG OF REINFORCED CONCRETE TWIN COLUMNS

Based on the test results of thirty six test pieces of four shear span ratios,five reinforcement styles,three web reinforcement styles and different axis tension ratios respectively,and under various axial tensile and compressive forces,the tensile leg of the reinforced concrete twin columns was studied;it's failure mechanism and the effects that different factors have on it's inclined|section bearing capacity were analyzed through contrast,and the practical calculating method of the inclined|section bearing capacity of the tensile leg of the reinforced concrete twin columns was put forward on the basis of statistical analyses and rational simplifications.
