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

摘要:

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.

Abstract:

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.
