This paper presents an experimental and numerical study into the behaviour of rubberised concrete-filled steel tubes (RuCFST), incorporating concrete with relatively high rubber replacements up to 60% mineral aggregates by volume. Axial compression, eccentric three-point bending tests on circular specimens are carried out results used validate nonlinear procedures adopted in continuum finite el...

The energy absorption of concrete filled, hollow-steel bracing was analyzed respect to geometric and mechanical parameters including the width-to-thickness section ratio, slenderness level, and strength of the steel and concrete. Local buckling and ductility were also investigated with respect to variation in the cross-section. The infill increased the compression resistance, even after multipl...

Numerous studies on masonry infill panels have greatly contributed to the research of strength, stiffness and energy dissipation capacity various buildings. If effects are disregarded, structural damage will occur under any significant ground motion, even lead collapse entire structure. The mode failure is strongly dependent RC frame interaction. This work proposes an evaluation method for dete...

In the SAGD process with dual horizontal wells in heterogeneous reservoirs, injection pressure of steam huff-n-puff by infilled interwell vertical is too high, and heat communication between wellpairs long, which leads to a series problems. The solvent-assisted well stimulation (LASER) technology proposed solve problems above. solvent formula was optimized, its key mechanism studied viscosity r...

In recent decades, steel frames infilled with precast load-bearing walls have been successfully employed as lateral load-resisting structural systems in high-rise buildings. This is due to their efficiency outer and major inner facades the higher construction speed of building. paper presents a detailed experimental investigation sustainable, prefabricated, composite wall system, using represen...
