国内外型钢混凝土柱承载能力计算方法比较

Comparison of Bearing Capacity Calculation Methods in the Specification for Concrete-encased Composite Columns

在型钢混凝土柱抗震性能试验研究的基础上,对美国AISC、ACI和我国《钢骨混凝土结构设计规程》(YB 9082-2006)、《型钢混凝土组合结构技术规程》(JGJ 138-2001)中有关型钢混凝土柱正截面承载能力、斜截面抗剪承载能力的计算理论和计算方法进行了简要介绍,并结合型钢混凝土柱承载力试验数据对规程中计算方法和计算结果进行了对比分析,为选用较合适的设计方法提供了参考和建议。

According to the experimental research on seismic behavior of concrete-encased column,the design methods and calculations of bearing capacity of concrete-encased composite columns are taken into consideration.The specifications included ACI,AISC and the two specifications in our country are Technical Specification for Steel Reinforced Concrete Composite Structures and Specification for Steel Reinforced Concrete Structures.Combined with tests data,analysis and comparison of calculation methods,results are put forward,which provide some suggestions for the selection of design methods.
