RISComponent-Based Modeling for Steel and Composite Beam-Column Joints Subjected to Quasi-Static and Impact Loads under Column Removal Scenarios
Publisher: ASCE
Abstract: This paper describes a component-based modeling approach for bare steel and composite beam-column joints subjected to quasi-static and impact loads under column removal scenarios. Two types of beam-column joints, viz. fin ...
Experimental Study on Composite Beam with Various Connections under Midspan Impact Scenarios
Publisher: ASCE
Abstract: The performance of an immediate frame span subjected to a falling-debris-impact scenario is of great importance to investigate the spread of initial damage during a progressive collapse event. If the frame span was not ...
An Efficient Solution for Wire Sweep Analysis in IC Packaging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Various methodologies of wire sweep analysis have been introduced to get better prediction and matching the experimental measurements by many researchers. As more and more high pin-count packages ...
Mitigation of Early-Age Cracking of Concrete Based on a New Gel-Type Superabsorbent Polymer
Publisher: American Society of Civil Engineers
Abstract: Shrinkage cracking of concrete at an early age has notable and adverse effects on the durability and long-term performance of the material because it damages surface integrity or undermines overall uniformity of concrete. ...
Structural Behavior of Composite Moment-Resisting Joints under Column-Removal Scenario
Publisher: ASCE
Abstract: One series of five composite joints with welded connections was tested and the influences of joint type, slab thickness, and number of shear studs were studied. Welded unreinforced flange with bolt web and reduced beam ...
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 ...
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 ...
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 ...
Mechanical Performance of Circular Ultrahigh-Performance Concrete–Filled Double Skin High-Strength Steel Tubular Stub Columns under Axial Compression
Publisher: ASCE
Abstract: This paper proposed a new type of stiffened circular ultra-high performance concrete-filled double skin steel tubular (UHPCFDST) column, in which stiffeners were applied to connect both inner and outer steel tubes. It ...
