摘要
以36根型钢混凝土(SRC)梁构件为数据样本,分析了包括YB 9802—2006《钢骨混凝土结构技术规程》、JGJ 138—2001《型钢混凝土组合结构技术规程》、根据型钢上翼缘受力状态的分类讨论方法以及基于MATLAB的条带法在内的4种SRC抗弯承载力计算方法的适用性及准确性。另外,对分类讨论方法中截面受压区高度的计算过程进行简化,得到了相关的简便计算方法,在简化计算的同时能够保证较好的精度。
Four calculation methods were introduced and used to analyze the applicability and accuracy based on 36 steel reinforced concrete(SRC) flexural members’ experimental data. The four methods include approaches in two Chinese codes YB 9802-2006 Constructtion Schemes of Steel Reinfored Concrete and JGJ 138-2001 Technical Specification for Steel Reinforced Concrete Composite Structures , the method based on the stress state of top flange and the section layer method based on Matlab. In addition, the paper simplified the calculation process of depth of compressive zone in the method based on top flange’s stress state and it is found that the simplification method possesses a certain accuracy already.
