RISTwo-Surface Plasticity Model for Cyclic Undrained Behavior of Clays
Publisher: American Society of Civil Engineers
Abstract: Based on a new type of kinematic hardening and the theory of critical state soil mechanics, a two-surface model is herein developed for predicting the undrained behavior of saturated cohesive soils under cyclic loads. The ...
Safety Assessment of Widened Bridges Considering Uneven Multilane Traffic-Load Modeling: Case Study in China
Publisher: ASCE
Abstract: Several bridges now require widening owing to the continuous development of road transport. However, the standard of traffic load in design specifications has been enhanced. Consequently, old bridges may not meet the safety ...
Virtual Reality’s Influence on Construction Workers’ Willingness to Participate in Safety Education and Training in China
Publisher: ASCE
Abstract: Construction workers’ willingness to participate in safety education and training (SET) greatly influences its effect and is important for improving safety. The development of virtual reality (VR) has innovated the SET ...
Elastoplastic Two-Surface Model for Unsaturated Cohesive Soils under Cyclic Loading
Publisher: ASCE
Abstract: This paper presents an elastoplastic two-surface model for the description of the stress–strain behavior of unsaturated cohesive soils under suction-controlled cyclic loading conditions. First, the model was developed ...
DEM Analysis of Mechanical Behavior of Unsaturated Silt under Strain-Controlled Constant Stress Ratio Compression Tests
Publisher: ASCE
Abstract: The three-dimensional discrete element method (DEM) is employed to investigate the macro- and microscopic mechanical behaviors of unsaturated silt subjected to one-dimensional (K0) and constant stress ratio loadings. A DEM ...
Influencing Factors and Critical Paths of Virtual Reality Adoption by AEC Enterprises Based on TOE-SNA
Publisher: ASCE
Abstract: Virtual reality (VR) holds significant potential for the architecture, engineering, and construction (AEC) industry. However, its adoption by AEC enterprises remains relatively low. VR adoption is affected by many factors, ...
Influence of Sea Surface Warming on Environmental Factors Affecting Long-Term Changes of Atlantic Tropical Cyclone Formation
Publisher: American Meteorological Society
Abstract: Despite the observed high correlation between the Atlantic sea surface temperature (SST) and the Atlantic tropical cyclone (TC) activity, interpretation of this relationship remains uncertain. This study suggests that the ...
Intensified Impact of East Indian Ocean SST Anomaly on Tropical Cyclone Genesis Frequency over the Western North Pacific
Publisher: American Meteorological Society
Abstract: recent finding is the significant impact of the sea surface temperature anomaly (SSTA) over the east Indian Ocean (EIO) on the genesis frequency of tropical cyclones (TCs) over the western North Pacific (WNP). In this study ...
Elastoplastic Modeling for Crushable Sands over a Large Stress Range Based on the Particle Rearranging and Crushing State
Publisher: American Society of Civil Engineers
Abstract: The stress–strain behavior of granular soils is related largely to their grain-size distributions and density. If sand particles are crushed under load, some basic physical and mechanical properties of sands will be changed ...
Analytical Solution for Pipeline Settlement Law Using Shield Tunnel Excavation Underneath Based on Vlasov–Timoshenko Model Considering Lateral Soil Action
Publisher: American Society of Civil Engineers
Abstract: This study used a two-stage method to derive an analytical solution for assessing the vertical displacement of an existing pipeline caused by the undercrossing construction of a shield tunnel. The aim was to evaluate the ...
