摘要

摘要: 型钢混凝土(SRC)柱截面承载能力计算主要有基于钢筋混凝土柱承载能力计算模式、钢结构柱容许应力法和叠加原理的型钢混凝土柱计算方法。在简单介绍基于上述各种模式的ACI、AISC-LRFD、我国冶金行业标准(YB规程)采用的简单叠加法及冶金行业标准条文说明中建议的型钢混凝土柱截面承载能力四种主要计算方法基础上,通过算例比较,对四种典型计算模式的计算方法和计算步骤进行详细介绍。基于已有试验研究结果,对各种计算方法所得结果与试验结果及各计算模式进行比较分析。结果表明,四种计算模式中,AISC-LRFD计算SRC柱截面承载能力较为保守,ACI和冶金部行业标准计算方法所得结果与试验结果比较接近,并且计算也较方便。

Abstract: The calculation methods to calculate load-bearing capacity of steel reinforced concrete(SRC) column are mostly based on calculation of the bearing capacity of reinforced concrete column,the allowable stress law of steel column and the superposed method.Four typical calculation methods respectively based on the above patterns provided by ACI-318-02 specification,AISC-LRFD design code,and the Specification for SRC structure(YB 9082-97) of China are introduced.According to a calculation example of load-bearing capacity of SRC eccentrically compressed,calculation method and steps of the four routine calculations pattern are presented.Load-bearing capacities of a series of SRC columns specimens tested before in references are also calculated using the method of the above specifications and codes,and comparison analysis between calculated results and test results are also conducted.It is denoted that among the four typical methods,the AISC-LRFD calculation method provides very conservative calculation results,calculation methods of the ACI specification and YB 9082-97 specification provides results close to the test results.
