RISStudy of I-Shape Steel Beams Subjected to Combined Fire and Impact Loading and Failure Assessment Method
Publisher: ASCE
Abstract: To investigate the dynamic response and fire performance of steel beams under high temperature, drop hammer impact tests and numerical simulations were conducted on steel beams subjected to high temperatures. Three finite ...
Numerical Simulation and Design of Progressive Collapse of Steel Frame Composite Structures Considering Falling-Floors Impact
Publisher: American Society of Civil Engineers
Abstract: Progressive collapse is a phenomenon where initial local failure of a component spreads to surrounding components, resulting in the collapse of the entire structure or most of it. This research is based on the component ...
Axial Compressive Behavior of Thin-Walled Concrete-Filled Double-Skin Steel Tubular Stub Columns with Connecting Strips
Publisher: ASCE
Abstract: Concrete-filled double-skin tubular (CFDST) columns have high fire resistance, and are widely used in the construction of electrical towers and bridges. However, previous research showed that the buckling of steel tubes ...
Experimental Study on the Behavior of a Novel Stiffened Hexagonal CFDST Stub Column under Axial Load
Publisher: ASCE
Abstract: A concrete-filled double skin tube (CFDST) consists of an outer steel tube, an inner steel tube, and the space between them filled with concrete. Existing studies have shown that the buckling of steel tubes can be significant ...
