RISTime Integration Method with High Accuracy and Efficiency for Structural Dynamic Analysis
Publisher: American Society of Civil Engineers
Abstract: In this study, a novel composite time integration method is proposed for more accurately and efficiently solving typical structural dynamic problems. In this method, the second-order accuracy is ensured for dynamic problems. ...
Active Stability Analysis of 3D Shallow Tunnel Face with Longitudinally Inclined Ground Surface Based on Nonlinear Mohr–Coulomb Failure Criterion
Publisher: ASCE
Abstract: The longitudinally inclined (the tunnel excavation direction) ground surface often appearing at the shallow tunnel entrance and exit zone threatens and reduces the tunnel face stability. However, studies on this stability ...
Upper-Bound Limit Analysis of Rock Slope Stability with Tensile Strength Cutoff Based on the Optimization Strategy of Dividing the Tension Zone and Shear Zone
Publisher: ASCE
Abstract: The contribution of tensile cracks to the stability of cracked slopes is important. The tensile characteristics of tensile cracks have a significant influence on the stability of rock slopes. Therefore, in this paper, based ...
