摘要
拓扑优化技术经过多年的发展已成为结构设计的有力工具。在过去的十年中,拓扑优化在结构工程领域内涌现出一批具有创新性的应用。从结构理论到构件设计,再到整体结构找形,这些应用涉及工程结构的各个层面。拓扑优化在这些应用中被视为一种突破传统设计的重要方法。本文对拓扑优化在结构工程中的应用进行了归纳与梳理,并对拓扑优化方法在钢筋混凝土构件设计、结构构件布置、构件形态设计、结构找形中具有代表性的应用研究进行了介绍;然后对其发展现状进行了讨论;最后对其发展趋势与潜在的应用方向进行了展望。
Topology optimization has undergone a long period of development and become a powerful tool for structural design.Over the last decade,topology optimization inspired innovative applications in structural engineering.These applications involve multiple levels of engineering structures,from structural theories to designs of structural members,then to form finding of a whole structure.Topology optimization is viewed as an important method for breaking through traditional designs in these applications.This paper summarizes these applications,and also provides an overview of some representative ones in designing reinforced concrete members,layout of structural members,morphology of structural components and structural form finding.The current status of applying topology optimization in structural engineering is discussed.The development tendency and potential applications are prospected at the end of this paper.
