广义组合结构及其发展展望

The development and prospect of generalized composite structures

本文对组合结构的发展历史和当前的研究及应用现状进行了综述。根据钢-混凝土组合结构的发展趋势和新材料的不断出现和应用,本文提出了广义组合结构的概念。广义组合结构不仅包括钢和混凝土的组合,而且包括更多新材料的组合,是对传统钢-混凝土组合结构的发展。广义组合结构将不同的材料或构件组合在一起共同工作,在设计时将各组成材料和构件的结构性能进行整体考虑,以最有效地发挥各种材料和构件的优势。此外,还对新型组合构件的研发、组合结构体系的创新、组合加固技术的发展以及组合结构在其他领域内的研究和应用进行了展望。

A review and prospect of the development of composite structures are provided in this paper. Based on the analysis, the concept of generalized composite structures is proposed. The generalized composite structure is the combination of different materials or the combination of different structural members in the ways which will generate composite actions between each component. In design, the structural property of each material and member should be considered as unity, and the combined structure will generate advantages from each component for strength, stiffness, ductility, durability, corrosion-resistance and overall costs. Finally, the prospects of research and development of new kind of composite members, composite systems, composite rehabilitation technology and applications of composite concept in other civil engineering fields are also presented in this paper.
