RISEnhanced Voids Growth Model for Ductile Fracture Prediction of High-Strength Steel Q690D under Monotonic Tension: Experiments and Numerical Simulation
Publisher: ASCE
Abstract: Accurate prediction of progressive damage and failure of structural steels is a nontrivial issue in practical design and assessment of steel structural buildings. It appears far more important in the fracture-oriented ...
Progressive Collapse of 3D Composite Floor Systems with Rigid Connections under External Column Removal Scenarios
Publisher: ASCE
Abstract: Progressive collapse of building structures has been a hot research topic since the September 11, 2001, terrorist attacks. These works provide valuable information focused more on beam–column connections and two-dimensional ...
Rigid-Plastic Model for Progressive Collapse Assessment of Composite Beam-Column Connection Subassembly under Internal Column Removal
Publisher: ASCE
Abstract: This paper investigates the progressive collapse behavior of composite beam-column connection subassembly under column removal scenarios. An analytical model is proposed based on the rigid-plastic assumptions, in which the ...
Study 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 ...
Enhancing the Collapse Resistance of a Composite Subassembly with Fully Welded Joints Using Sliding Inner Cores
Publisher: American Society of Civil Engineers
Abstract: This study presents a novel approach to enhancing the progressive collapse resistance of a fully welded joint (FWJ) by introducing sliding inner cores within the joint, which is referred to as the FWJ with sliding inner ...
Comparative Study of Uncoupled Ductile-Fracture Models on Fracture Prediction of Structural Steels under Monotonic Loading
Publisher: ASCE
Abstract: Since the middle of the last century, numerous fracture models have been reported in the literature. These models, whether proposed on the basis of theoretical derivation, experimental observation, or a combination of the ...
Experimental and Analytical Study on Progressive Collapse of 3D Composite Floor System under Corner Column Loss
Publisher: ASCE
Abstract: The propensity of buildings to progressively collapse can be assessed using the alternative path method. Generally, there are three scenarios to be considered: internal column, side column, and corner column removals. ...
Experimental Study on Progressive Collapse of 3D Steel Frames under Concentrated and Uniformly Distributed Loading Conditions
Publisher: ASCE
Abstract: Structures are expected to be robust enough to avoid widespread local failure caused by extreme loading events, so that the complete or disproportional collapse of buildings can be averted. In the last decades, numerous ...
Vertical Progressive Collapse of Cmposite Floor Systems under a Side Column Removal Scenario: Experimental and Numerical Investigations
Publisher: ASCE
Abstract: The propensity of buildings for progressive collapse can be assessed using the alternative path method. Generally, there are three scenarios to be considered: internal column, side column, and corner column removals. Many ...
