RISNondeterministic 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 ...
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, ...
Macromodeling of Crack Damage in Steel Beams Subjected to Nonstationary Low Cycle Fatigue

Shear Behavior of Panel Zones in Steel Beam-to-Column Connections with Unequal Depth of Outer Annular Stiffener
Publisher: American Society of Civil Engineers
Abstract: This paper presents an experimental investigation of the shear behavior of steel beam-to-column connections with unequal depth of outer annular stiffener. The depth-to-thickness ratio (D∶t) of the hollow structural section ...
Bayesian 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 ...
