RISImproved Estimation of the Seismically Induced Active Earth Thrust on a Cantilever Retaining Wall at the Preliminary Design Stage
Publisher: American Society of Civil Engineers
Abstract: Numerical investigation of free-standing cantilever walls subjected to horizontal seismic loads was carried out using nonlinear elastoplastic finite-element approach. The numerical model was validated using centrifuge tests ...
Effect of Combined Blast and Fragment Loading on RC Wall and Its Mitigation Using Composite Sections
Publisher: ASCE
Abstract: The damages incurred in RC walls subjected to combined loading of blast and fragment as a result of a cased-charge detonation are studied here using the finite-element (FE) analysis method. A series of FE analyses were ...
Numerical Analysis of a Tunnel Subjected to Blast Loads in a Transversely Isotropic Rock Mass
Publisher: American Society of Civil Engineers
Abstract: The present study investigates the stability of a tunnel subjected to blast loads. The tunnel is placed in a transversely isotropic rock mass. Numerical simulations are performed using the discrete-element method. The rock ...
Thermomechanical Analysis and Parametric Study of Geothermal Energy Piles in Sand
Publisher: American Society of Civil Engineers
Abstract: Response of geothermal energy piles in sand under combined thermal and mechanical loading was investigated in the present work using a nonlinear axisymmetric finite-element (FE) analysis procedure. In this study, the piles ...
Thermomechanical Response of Geothermal Energy Pile Groups in Sand

Determination of High-Strain-Rate Stress–Strain Response of Granite for Blast Analysis of Tunnels
Publisher: American Society of Civil Engineers
Abstract: The present work aims to understand the stress–strain response of an igneous rock, granite, under high loading rate through detailed experimental and numerical analyses. The high-strain-rate characterization of granite ...
Dynamic Response of Two Extrusive Igneous Rocks Using Split Hopkinson Pressure Bar Test
Publisher: ASCE
Abstract: In this paper, the stress-strain response of two extrusive volcanic igneous rocks, e.g., compact basalt (CB) and volcanic breccia (VB), under a high rate of loading is studied experimentally and numerically. The dynamic ...
Nonlinear Elastoplastic Analysis of Plates Coupled with Mechanical Element–Based Isolation System
Publisher: ASCE
Abstract: In general, the response of a system coupled with a vibration absorber is obtained by incorporating only elastic analysis under different loading conditions. However, the elastoplastic analysis is carried out for blast-resistant ...
Nonlinear Buckling Analysis of Slender Piles with Geometric Imperfections
Publisher: American Society of Civil Engineers
Abstract: The buckling response of straight and initially bent, i.e., geometrically imperfect, end-bearing piles in soil subjected to axial load has been examined in the current study through FEM, considering geometric and material ...
