RISBayesian Updating: Reducing Epistemic Uncertainty in Hysteretic Degradation Behavior of Steel Tubular Structures
Publisher: ASCE
Abstract: This paper proposes a probabilistic framework for updating the governing parameters in the hysteretic constitutive model for tubular steel with strength degradation. The hysteretic constitutive model is formulated to track ...
Nondeterministic High-Cycle Fatigue Macromodel Updating and Failure Probability Analysis of Welded Joints of Long-Span Structures
Publisher: American Society of Civil Engineers
Abstract: Unlike previous models that do not consider uncertainties, this paper proposes a new nondeterministic method to estimate the high-cycle fatigue (HCF) resistance of welded hollow spherical joints (WHSJs) in long-span ...
Stability of Sway-Inhibited Prismatic Columns Subjected to Internal Axial Loads

Vibration of Prestressed Cable RC Truss Floor System due to Human Activity
Publisher: American Society of Civil Engineers
Abstract: Vibration has become a serious serviceability problem due to the large openings of girder, lightweight floor systems, and high-strength materials used in practice. The results from both heel-drop and jumping floor vibration ...

Abstract: Vibration has become a serious serviceability problem due to the large openings of girder, lightweight floor systems, and high-strength materials used in practice. The results from both heel-drop and jumping floor vibration ...
Fatigue Behavior of Rib-to-Floor Beam Junctions with Separate Inner Stiffeners in Orthotropic Steel Bridge Decks
Publisher: ASCE
Abstract: The fatigue of orthotropic steel bridge decks (OSBDs) is a bottleneck for its application, especially the fatigue of rib-to-floor beam (RF) junction. Thus, it is necessary to optimize the RF junction to improve its fatigue ...
Influence of Architectural Facades on Wind Pressures and Aerodynamic Forces of Tall Buildings
Publisher: ASCE
Abstract: Architectural facades including balconies, mullions, shading boards, and ribs are widely used outside of tall buildings for the purpose of aesthetics and function. And these facades will affect the wind loads of tall ...
Effect of Strain Rate on the Bond Performance of Carbon Fiber–Reinforced Polymer Tendons in Ultrahigh-Performance Concrete
Publisher: American Society of Civil Engineers
Abstract: This paper aims to investigate the contribution of chemical adhesion and friction to the bond stress of a smooth carbon fiber–reinforced polymer (CFRP) tendon in ultrahigh-performance concrete (UHPC) under different strain ...
Effect of Low-Temperature Fluctuations on Martian Steel Structures: Numerical and Analytical Studies
Publisher: American Society of Civil Engineers
Abstract: To harness a variety of unique resources, humanity is progressively venturing deeper into space. This endeavor necessitates a comprehensive investigation into the formidable challenges presented by hostile environments, ...
Seismic Behavior Tests of Square Reinforced Concrete–Filled Steel Tube Columns Connected to RC Beam Joints
Publisher: American Society of Civil Engineers
Abstract: This paper proposes a joint system that connects the thin-walled square reinforced concrete–filled steel tube (RCFST) column to RC beams at both sides of the joint. In order to delay the local buckling of square steel tubes ...
