型钢混凝土梁正截面受弯承载力计算理论的对比分析

文章在介绍型钢混凝土梁正截面受弯承载力的计算理论的基础上,阐述了我国两部型钢混凝土结构设计规程中有关型钢混凝土梁正截面受弯承载力的计算理论,并结合型钢混凝土梁正截面受弯承载力的试验数据和工程实例对两部规程中的型钢混凝土梁正截面受弯承载力的计算方法和计算结果进行了对比分析.基于对比分析结果,提出了工程应用时两部规程的选用原则及其适用范围.在两部规程没有按现行的《建筑结构可靠度设计统一标准》(GB50068-2001)的要求进行修订之前,基于该统一标准对结构可靠度的要求,提出了现阶段使用两部规程时的具体措施.

Comparative study on the calculation theory for the flexural capacity of steel reinforced concrete beams

The calculation theories adopted for two specifications in the design of steel reinforced concrete structures in our country were expounded after three calculation theories of the flexural capacity of steel reinforced concrete beams were introduced.And the comparison and analysis of the calculation method and calculation results witk the two specifications were made by means of experimental data of steel reinforced concrete beams and engineering project.According to the results of the comparative analysis,principles chosen and suitable scopes of two specifications were presented for engineering application.With regard to the demand of Unified Standard for Reliability Design of Building Structures(GB50068-2001),the particular measures of applying two specifications were put forward before revision in the light of the demand of the unified standard.
