摘要

基于有限元分析的拓扑优化技术在许多领域得到了广泛的应用，但大多数研究和应用都是基于单一材料结构。在双向进化结构优化（BESO）方法的基础上，提出了一种新的多材料三维结构拓扑优化技术。根据设计域中每个元件的主应力之和，将指定更适合该元件的材料。通过一个钢-混凝土悬臂梁、两种不同的桥梁和四层体系的算例，验证了该方法在钢-混凝土组合结构概念设计中的有效性和实用价值。

Evolutionary Topology Optimization of Spatial Steel-Concrete Structures

Topology optimization techniques based on finite element analysis have been widely used in many fields, but most of the research and applications are based on single-material structures. Extended from the bi-directional evolutionary structural optimization (BESO) method, a new topology optimization technique for 3D structures made of multiple materials is presented in this paper. According to the sum of each element's principal stresses in the design domain, a material more suitable for this element would be assigned. Numerical examples of a steel- concrete cantilever, two different bridges and four floor systems are provided to demonstrate the effectiveness and practical value of the proposed method for the conceptual design of composite structures made of steel and concrete.
