钢筋混凝土简支板优化设计方法

Optimized Design for Simple Supported Beam of Steel Reinforced Concrete

对于公路桥梁中常用的简支板，选取截面有效高度及受拉钢筋面积作为设计变量，以简支板造价作为目标函数，并以现行《公路钢筋混凝土及预应力混凝土桥涵设计规范》（ＪＴＪ ０２３－８５）为依据，提出钢筋混凝土简支板的优化设计方法。

Based on the current Design Standard of Highway Steel Reinforced Concrete and Pre- stress Steel Reinforced Concrete Bridge and Culvert (JTJ023- 85), choosing section effective height and pulled steel area as design variables, cost of simple supported beam as target function,the article puts forward an optimized design for simple supported beam of steel reinforced concrete.
