摘要
现代建筑业正往超高、超大跨度等方向发展,普通型钢混凝土结构已经不能满足时代要求,活性粉末混凝土(Reactive Powder Concrete,RPC)作为新一代超高性能混凝土,与型钢相结合具有更高的承载力和耐久性,是未来组合结构研究的热点。为推动这一组合结构的研究与发展,介绍RPC各项性能的研究情况,探讨RPC在现阶段以及型钢混凝土结构中的应用,分析这种新型组合构件的优点。在此基础上,指出今后开展型钢活性粉末混凝土组合结构的研究工作时需要考虑的研究方向。
The modern construction industry is developing in the direction of uhra-high and ultra-large spans. The common steel reinforced con- crete structure can no longer meet the requirements of the times. The Reactive Powder Concrete（RPC） is a new- generation of uhra-high perform- ance concrete and will has higher bearing capacity and durability if combined with the steel. Which is a hot topic in the future research of compos- ite structures. To promote the research and development of this composite structure, this article introduces the research status of RPC perform- ance, discusses the engineering application of RPC at the current stage, discusses the application of RPC at present stage and steel reinforced concrete structure, analyzes the advantages of this composite component. Based on this, it points out the research direction that needs to be con- sidered in the future research work on the combined structure of steel and reactive powder concrete.
