厦门东方时代广场劲性柱施工技术

The construction technology for stiffness columns in Xiamen east times plaza

在钢筋混凝土框架柱中竖向设置型钢,可减小柱轴压比,提高承载力并增强结构抗震性能,近年来在高层建筑中广泛采用,以厦门东方时代广场大量采用钢筋混凝土劲性柱为例,从实践的角度系统地介绍劲性柱从制作、安装到最后成型全过程的施工体会。

To lace channels virticaUy in concrete bar structure, can reduce the column-axial load ratio, can raise the carrying capacity and strengthen aseismic performance. In recent years, this technology already has been taken used in many high buildings. My article will take the stiffness columns which are common used in Xiamen east times plaza as example, from the actual site practice point, to introduce systemly it＇s manufacturing, installation and forming.
