公路钢筋混凝土简支T梁优化设计

Optimun design of simple-supported R.C.T-beam for highway

对公路常用的简支 T梁选取截面有效高度及受拉钢筋截面面积作为设计变量 ,以 T梁造价作为目标函数 ,并以现行《公路桥规》为依据 ,提出了钢筋混凝土

The effective depth of cross-section for the simple-supported T-beam used commonly for highway and its area of tensile steel bars are taken to be as the design variables, the construction cost of T-beam is used for the objective function, on the basis of the Specifications for Construction of Highway Bridges and Culverts, this article put forwards to the optimum design method for reinforced concrete (R.C.) T-beam.;
