钢骨混凝土异形柱正截面承载力研究

THE RESEARCH ON AXIAL COMPRESSION AND BIAXIAL BENDING CAPACITY OF SPECIAL-SHAPED SRC COLUMN

采用数值积分的方法编写了钢骨混凝土异形柱在单、双向偏心受压时的正截面承载力计算程序。并对收集到的试验数据进行了数值计算,验证了程序的正确性。通过对钢骨混凝土T、L、十字形截面柱在不同的混凝土等级、配钢率、配筋率以及不同的荷载角情况下的计算,得出了影响钢骨混凝土异形柱正截面承载力的因素及变化规律。

A program which calculates the axial compression and biaxial bending of specialshaped SRC column under axial compression and biaxial bending condition is completed by numerical integration method.The collected test data have been calculated which are compared with calculating data,and the correction of program has been certified.According to the analytical results of T,L and cross SRC columns under the conditions of different concrete grade,steel ratio,reinforcement ratio and loading angles,the factor which influences the SRC column and the changing rule have been elicited.
