摘要
基于型钢混凝土结构构件的粘结滑移理论和受力性能研究,提出了型钢混凝土框架结构柱单目标离散型变量优化设计方法。设计变量取结构构件几何尺寸、截面尺寸、材料强度和型钢截面尺寸,目标函数取构件的造价,约束条件为型钢混凝土组合结构基于粘结滑移理论的设计计算理论以及现行设计规范中所规定的合理的设计基本要求、计算要点和构造措施。为型钢混凝土框架结构的优化设计提供了实用方法与途径,亦可为其他型钢混凝土结构的优化设计提供参考。
Based on experimental study of bond-slip behavior between steel and concrete,an optimal design scheme of single objection and discrete variables is proposed to design steel reinforced concrete（SRC） frame columns.In the optimum scheme,design variables include the layout dimensions of SRC frame structure,structural member sections,strengths of concrete and steel,dimensions of steel shape.The objective function is cost of the entire materials applied to construct SRC frame structure.The constraint conditions are main requirements stated in Chinese code for design of SRC structures,basic design rules,reasonable calculating theories and indispensable constructions,as well as some mature and consistent conclusions confirmed by experimental studies on calculating methods of SRC structures based on the bond-slip theory between steel shape and concrete.These may be a reference in analyzing and designing SRC frame structures and provide a practical method satisfying civil engineering practice and requirements stated in the codes.
