摘要
在预应力技术和组合结构研究的基础上,结合这两者的优势,在钢与混凝土组合结构中施加预应力,形成预应力钢与混凝土组合结构,可以充分发挥这几种材料的特性,降低构件的尺寸,取得较好的力学性能。针对我国目前预应力技术的研究和运用现状,在对预应力钢结构概述的基础上,介绍了预应力组合结构的特点、应用以及发展的前景。
Based on study of prestrss technology and composite structure, after introducing prestress technology in composite structure, prestressed composite structure was proposed, which can fully use the advantage of the several materials, cut down the size of member, and acquire good mechanical properties. At last, current study of prestress in our country was outlined, and the features, use, and future of prestressed composite structure were introduced,
