RISThe Beta Drift of Three-Dimensional Vortices: A Numerical Study
Publisher: American Meteorological Society
Abstract: The beta effect on translation of cyclonic and anticyclonic vortices with height-dependent circulation (the beta-drift problem) is investigated via numerical experiments using a dry version of a multilevel primitive equation ...
Experimental Study of Novel Self-Centering Seismic Base Isolators Incorporating Superelastic Shape Memory Alloys
Publisher: ASCE
Abstract: This paper proposes novel self-centering (SC) seismic base isolators by utilizing shape memory alloy U-shaped dampers (SMA-UDs) with favorable superelastic behavior. Two different designs, which incorporate the SMA-UDs ...
Data Snooping for the Equality Constrained Nonlinear Gauss–Helmert Model Using Sensitivity Analysis
Publisher: ASCE
Abstract: To develop a universal-outliers processing algorithm under the conditions with equality constraints, the equality-constrained nonlinear Gauss–Helmert (GH) model, which contains the equality-constrained Gauss–Markov (GM) ...
Microscale Fracture Damage Analysis of Lightweight Aggregate Concrete under Tension and Compression Based on Cohesive Zone Model
Publisher: ASCE
Abstract: The secondary pre-processing development of Abaqus based on the Python program is carried out, and the mesoscale finite-element model of light-aggregate concrete is established at mesoscale. A Python program capable of ...
