型钢混凝土柱中型钢的板件宽厚比限值

Limit Value of Steel Plate Width-to-Thickness Ratios of Steel Reinforced Concrete Column

运用有限元软件AYSYS对型钢混凝土柱中型钢的宽厚比限值进行数值分析,综合考虑材料非线性、几何非线性及接触非线性,分析了5组共80个构件,拟合出计算公式.与中国现行《型钢混凝土组合结构技术规程》比较,结果表明该公式与规程的建议基本符合,可供工程设计和规范参考.

With the finite software ANSYS, a formula is simulated on the basis of the analysis results of 80 samples with a consideration of geometry nonlinear, material nonlinear and contact nonlinear. The results from the formula agree well with those specified in Chinese Code Steel Reinforced Concrete Composite Structure Specification. The formula can provide a reference for the engineering design.
