钢与高强混凝土组合梁截面高度的取值研究

Study of Section Height for The Concrete-High Strength Steel Combinatorial Beam

基于钢与高强混凝土组合梁承载能力极限状态及正常使用极限状态下的工作机理基础上 ,通过分析钢与高强混凝土组合梁的高度的组成 ,确定出梁的混凝土的高度hc 及型钢腹板净高度hw 为设计变量 ,并以hc 与hw 之和为目标函数 ,在考虑弯曲约束条件、剪切约束条件、变形约束条件、整体稳定约束条件的情况下 ,分别按弯曲强度、剪切强度和变形约束的要求对组合梁高度取值的优化设计进行了探讨 ,得出了优化设计后的结果 。

Based on the working principle of the concrete high strength steel combinatorial beam in bending and common limited state,an analysis is made of the composition of height of beam and a math mode is set up It has been calcnlated that design variable is that h c and h w?aim function that h c plus h w on restricted condition of bending and shearing,An optimize design has been obtained for the height of the concrete high strength steel combinatorial beam.
