摘要
桥梁结构一般受到恒载和活载的作用,在结构的拓扑优化过程中,必须考虑载荷的变化.导出了涉及桥梁结构恒载和活载的多载荷工况的应变能灵敏度公式,建立了考虑应力和应变能要求的多约束三维结构优化算法.
The bridge structures generally support the dead load and the live load.In the structural topology optimization process,the loading change must be considered.Thus,this paper gives the strain energy sensitivity formula that involves the bridge structural dead load and the live load for multiple load cases.And the multiple-constraint three dimensional structural optimization algorithm has been established,considering stress and the strain energy requirements.
