RISHuman–Machine System Modeling and Safety Risk Assessment in Construction Operations Incorporating Workers’ Performance Variability
Publisher: American Society of Civil Engineers
Abstract: The increasing involvement of diverse construction machines has significantly transformed construction operations. Within the nonlinear interaction of multiple worker and machine functions, workers’ performance exhibits ...
Evaluation on Deformation Behavior of Granular Base Material during Repeated Load Triaxial Testing by Discrete-Element Method
Publisher: ASCE
Abstract: Granular base material (GBM) is widely used as the base/subbase course of pavement structure. In the mechanic–empirical design of flexible pavement, both the resilient modulus and permanent deformation are the major ...
Three-Dimensional Simulation of Aggregate and Asphalt Mixture Using Parameterized Shape and Size Gradation
Publisher: American Society of Civil Engineers
Abstract: Aggregate occupies at least three-quarters of the volume of asphalt mixture and can significantly affect the performance of pavement. The geometrical morphology influences the slippage and interlock among aggregates for ...
Human Error Identification and Analysis for Shield Machine Operation Using an Adapted TRACEr Method
Publisher: ASCE
Abstract: This paper investigated shield machine operation (SMO) errors involved in shield tunneling construction accidents based on the Technique for the Retrospective and Predictive Analysis of Cognitive Errors (TRACEr). Human ...
