UNIFIED EQUATIONS FOR SOLID AND HOLLOW CONCRETE-FILLED TUBE COLUMNS UNDER COMPLEX STRESS:CORRELATION EQUATIONS
-
摘要: 通过理论推导，得出钢管混凝土构件在复杂应力下的承载力相关方程的基本形式。基于构件等效模型以及单独受力状态下的平衡方程，对复杂受力情况下的钢管混凝土进行受力分析，求出等效桁架中各杆的内力，确定其屈服破坏形态，最后得出屈服方程。利用前面的平衡方程，推导得出各外力间的承载力相关方程。考虑钢管和混凝土之间套箍作用的影响，对承载力相关方程中的各极限承载力项和组合项进行修正。

Abstract: This thesis is to obtain the basic form of the strength and stability capacity correlation equations of the concrete-filled steel tubular structures under complex stress through the theoretical derivation.It should be considered the role of the impact of hoop between the steel and concrete, analyzed and summarized the working performace and loading capacity of concrete-filled steel tubular structures subject to respective axial compression, bending, shear and torsion.It will be introducted a hoop influence coefficient to adjust the various ultimate bearing capacity of items, so as to get a practical calculation formula for the compression, flexural bearing capacity which can be in good agreement with experiment and finite element values.This practical formula considering the role of the impact of hoop will replace the correlating equation to adjust the carrying capacity to finalize the expression of the strength and stability capacity correlation equations of the concrete-filled steel tubular structures under complex stress. -
