SRC 结构的使用已有超过百年的历史,一百多年来,在世界各地已建有大量 的 SRC 结构,对 SRC 结构也进行了普遍的研究,并已有了各自的设计规范。 我国因 SRC 结构的用钢量较大,20 世纪 80 年代前未进行过广泛的应用。在 上世纪 50 年代,我国开始采用 SRC 结构,当时主要由前苏联设计,我国负责施工建设,比如包头电厂主厂房和鞍山钢铁公司的混铁炉基础。之后,由于各方面的原因,SRC 结构直到 80 年代后期才开始发展。著名的 SRC 结构建筑有1992年建成的深圳八一大楼,1994 年建成的上海世界金融大厦,1998 年建成的广州汽车大厦,还有近些年建成的建筑如陕西省信息大厦、深圳华融大厦、上海环球金融大厦、上海金茂大厦、北京京城大厦等。型钢混凝土复合结构(Steel Reinforced Concrete Composite Structure),简称 SRC 复合结构。型钢混凝土复合结构是指型钢混凝土(SRC)和现浇钢筋混凝土 (RC)或预制混凝土构件(PC)的组合结构。根据建筑功能及结构安全性能, 可以设计出多种组合的 SRC 复合结构,兼顾钢结构和钢筋混凝土结构的各自优点。
