Concrete-filled hollow structural steel (HSS) columns have been widely used in many constructions due to their excellent performances, such as higher strength and better fire resistance over bare steel columns, larger stiffness and ductility [1]. In the past, a large number of studies had been ...
The square steel tube is increasingly used in engineering practice to fabricate concrete-filled square steel tubular (CFSST) columns, with the improved bending stiffness and easy construction for column-beam connection [3,4]. Studies identified that, square steel tube has less effective confinement ...
Concrete-filled steel tubes have wide range of applications in building and civil engineering structures due to their excellent earthquake resisting charac... K Susantha 被引量: 1发表: 2013年 INVESTIGATION OF THE FLEXURAL AND BUCKLING BEHAVIOR OF CONCRETE FILLED STEEL TUBES (CFST) COLUMNS IN BRIDGE...

The actuators are placed on top of the columns and covered by a traverse that is connected to two steel rods per column. The steel rods are connected to the frame at the foundation beam of the frame with specially designed steel angles. This set-up allows the application of vertical loads...
A foundation form is pre-fabricated, shipped to job site, placed in a hole, leveled, and concrete is poured into it to form a large surface area footing topped by a pedestal having anchor bolts projecting therefrom to secure a cantilevered arm and mast, such as for traffic lights or railro...
The confined concrete arch is a high-strength coupled support system made of steel and concrete, which uses external confined material such as steel pipe to improve the compressive resistance of the core concrete, thereby improving the strength and rigidity of the system [18,19]. From: Internatio...
For example, while at the top levels workers are erecting steel columns and floor beams, steel fixers are placing the steel decking and installing the shear connectors at lower levels, followed two-three levels below by concreters pouring concrete, and other tradespeople completing and installing ...
