钢管混凝土柱-钢梁节点核心区受剪承载力计算对比研究
Comparison and analysis on design method of shear capacity of panel zone between CFT column and steel beam
摘要
Abstract
This paper investigates the experiments on composite joints between concrete filled tube columns and steel girders conducted in recent years and compares the test results with the calculation results of AIJ specification, Fukumoto calculation method and Nishiyama calculation method. By data analysis, the study confirms the applicability of the three methods. The ultimate shear capacity calculation results of Fukumoto and Nishiyama methods are more accurate and reliable than AIJ specification. By parametric analysis, the study confirms that the three methods have a broad applicability for joints of various axial compression ratios, connection formation and column cross section. This paper also suggests that the applicable steel strength ar,d concrete strength of AIJ specification should not exceed 450 MPa and 70 MPa respectively, the applicable steel yielding strength to concrete standard compressive strength should exceed 8. This paper also gives proposed amendments of formulas to suit for special formation of joints.关键词
