型钢混凝土柱的非线性推覆分析原理

以建立型钢混凝土柱简便、廉价、准确及易于使用的理论分析工具为目的，将非线性推覆分析方法运用到型钢混凝土柱的非线性分析，首先建立了型钢混凝土柱的非线性推覆分析模型和材料本构关系，然后利用此模型和本构关系编制了非线性推覆分析程序，最后使用本程序对已有试验数据的型钢混凝土柱进行计算，通过试验结果和理论计算结果的比较验证了程序的可靠性，结果表明：非线性推覆分析方法用于型钢混凝土柱的理论分析其概念明确、原理简单、容易实现、结果准确、耗时少、计算费用低，可以用于实用的目的．

Non-linear Push-over Analyzing Principles of SRC Column

Aiming at the creation of simple, cheap, accurate and easy-to-use theoretical analyzing tool for SRC columns, non-linear push-over analyzing method were applied to non-linear analysis of SRC column, firstly established the non-linear push-over analyzing model and material constitutive relation of SRC columns, and then using the model and the relation, composed the non-linear push-over analyzing program of SRC columns, finally the SRC columns that already have experinlental data were calculated to validate the reliability of the program, the results showed that the non-linear push-over analysis are definitive, easyto-use, accurate, time and money saving method when it is used to the calculations of SRC columns and can be applicable.
