Abstract
Based on experimental study of bond-slip behaviours between steel shape and
concrete, an optimal design scheme of single objective and discrete
variables is proposed to design steel reinforced concrete (SRC) frame beams.
In the optimum scheme, design variables include the layout dimensions of SRC
frame structure, structural member sections, strength of concrete and steel,
dimensions of steel shapes. 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.
Key words: SRC beam -- bond-slip theory -- optimum design -- mixing penalty function method
