HPFRCC装配整体式叠合柱抗震性能研究

Research on Seismic Performance of Monolithic Composite Column Assembled by HPFRCC

摘要: 随着我国建筑工业的快速发展，对建筑结构的抗震性能的要求也随之越来越高。装配整体式是利用钢筋混凝土预制成的模板，模壳内浇筑混凝土后形成叠合柱。使用装配整体式叠合柱不仅仅可以节省用于制作模板的材料，更能减少支设模板的时间，更加减少了模壳的自重，更有利于工程吊装使用。同时，装配整体式叠合柱的核心后浇区采用现浇的方式与试件中的其他构件连接成整体，大大地改善了装配整体式结构中存在的整体性不足的缺点。为了改善装配整体式的抗震性能，将其外壳用HPFRCC制成。本文主要概括国内外装配整体式与HPFRCC的研究现状，并且基于研究现状得到相应的结论。

Abstract: With the rapid development of building industry in our country, the requirement of seismic performance of building structures also becomes higher and higher. The assembly integral is the prefabricated form of reinforced concrete, and the composite column is formed after pouring concrete into the mold shell. The use of assembly of integral composite column can not only save the material used to make the template, but also reduce the time of setting up the template, and reduce the dead weight of the mold shell, which is more conducive to the engineering hoisting use. At the same time, the core post-casting area of the assembled integral composite column is connected with other components in the specimen by the way of cast-in-place, which greatly improves the shortcomings of the lack of integrity in the assembled integral structure. In order to improve the seismic performance of the whole assembly, the shell is made of high performance cement matrix composite material. This paper mainly summarizes the research status of assembled monolithic and high performance cement matrix composites at home and abroad, and draws corresponding conclusions based on the research status.
