RISNonlinear Analysis of Composite Beams with Partial Interaction in Steel Frame Structures at Elevated Temperature
Publisher: American Society of Civil Engineers
Abstract: Flooring systems containing steel-concrete composite beams are common in steel frame structures and it is widely recognized that their behavior under fire loading is profoundly different to that of simply supported composite ...
Seismic Performance Assessment of Built-Up High-Strength Steel Tubular Columns through Multiaxis Cyclic and Hybrid Simulation
Publisher: American Society of Civil Engineers
Abstract: This study investigates the seismic performance of built-up steel tubular (BST) columns composed of four mild-steel plates welded to four ultrahigh-strength steel (UHSS) tubes of Grade 1200, presenting a novel concept in ...
Numerical Modeling of Concrete-Filled Double-Skin Steel Square Tubular Columns under Blast Loading
Publisher: American Society of Civil Engineers
Abstract: Concrete-filled double-skin tubes (CFDST) have been widely used in constructing high-rise buildings, arch bridges, and factories over the past years. Although a number of researches have been conducted to study the behavior ...
Experimental Investigation of the Inelastic Cyclic Behavior of Concrete-Filled Double-Skin Tubular Beam-Columns with Corrugated Inner Skins and Ultrahigh-Strength Corner Tubes
Publisher: ASCE
Abstract: This paper presents the experimental results from nine full-scale concrete-filled double-skin tubular (CFDST) beam-columns. The test specimens exploited two fabrication strategies, featuring either hollow steel inner skins ...
