Centrifuge concrete - filled steel tube is a special kind of composite structure . it is made of a thin - wall steel tube and a centrifugal concrete tube inside 离心钢管混凝土是一种将混凝土浇灌在钢管内经离心成型的空心复合构件,它是介于纯钢管和离心混凝土管之间的一种特殊的钢管混凝土形式。
Transient temperature field comes from changes of boundary conditions and the heat which is produced by the concrete chemical reactions with the water during the mass concrete pouring 由于混凝土浇灌时产生的水化热和浇筑过程中热边界条件变化而产生瞬态温度场,这种温度场对结构施加时变温度载荷。
The analysis results indicate , this kind of buckling restrained brace having good dissipation energy ability , and improve the difficult in connection and quality of concrete casting 分析结果表明,这种防屈曲支撑具有良好的耗能能力,而且改善了常用防屈曲支撑所出现的连接困难,混凝土浇灌质量难以得到保证等问题。
