RISAccounting for Earthquake-Induced Dam-Reservoir Interaction Using Modified Accelerograms
Publisher: American Society of Civil Engineers
Abstract: This paper proposes a new practical and efficient procedure to investigate the seismic response of gravity dams that (1) avoids the finite or boundary element discretization of the impounded reservoir; (2) can be applied ...
Practical Formulas for Frequency Domain Analysis of Earthquake-Induced Dam-Reservoir Interaction
Publisher: American Society of Civil Engineers
Abstract: Dam-reservoir dynamic interactions are complex phenomena requiring advanced mathematical and numerical modeling. Although available sophisticated techniques can handle many aspects of these phenomena, simplified procedures ...
Critical Appraisal of Common Simplified Assumptions in Seismic Stability Analyses of Gravity Dams
Publisher: American Society of Civil Engineers
Abstract: In practical seismic stability analyses of gravity dams, it is common to (1) oversimplify irregular dam-rock interfaces, (2) neglect the effects of cohesion and tensile strength, and (3) ignore the effects of vertical ...

Experimental and Numerical Assessment of the Three-Dimensional Modal Dynamic Response of Bridge Pile Foundations Submerged in Water
Publisher: American Society of Civil Engineers
Abstract: This paper describes an experimental program conducted to investigate the effects of fluid-structure interaction on the modal dynamic response of three reduced-scale bridge pile foundations submerged partially or totally ...
Seismic Response of Asymmetric Rectangular Liquid-Containing Structures
Publisher: American Society of Civil Engineers
Abstract: A new formulation to investigate the seismic response of symmetric and asymmetric rectangular liquid-containing structures is developed and validated in this paper. The proposed method is based on a substructuring approach, ...
A Progressive Approach to Account for Large-Scale Roughness of Concrete–Rock Interface in Practical Stability Analyses for Dam Safety Evaluation
Publisher: ASCE
Abstract: This paper proposes a progressive approach to assess the properties of large-scale roughness at dam–rock interfaces and the implementation of their effects into practical dam stability analyses. The analysis steps, ranked ...
Thermal Modeling of Small Modular Reactors in Permafrost Regions Subjected to Climate Nonstationarity
Publisher: American Society of Civil Engineers
Abstract: Small modular reactors (SMRs) are an alternative for clean energy solutions in Canada’s remote northern communities, owing to their safety, flexibility, and reduced capital requirements. Currently, these communities are ...
Real-Time Dynamic Substructuring Testing of a Bridge Equipped with Friction-Based Seismic Isolators
Publisher: American Society of Civil Engineers
Abstract: This paper presents a real-time dynamic substructuring (RTDS) test program that was carried out on a bridge structure equipped with seismic isolators with self-centering and friction energy dissipation capabilities. The ...
Effects of Rock Foundation Roughness on the Sliding Stability of Concrete Gravity Dams Based on Topographic Surveys
Publisher: American Society of Civil Engineers
Abstract: This paper investigates the effects of rock foundation roughness on the shear strength of dam–rock interfaces and dam sliding stability. For this purpose, bathymetric and light detection and ranging (LiDAR) surveys of ...
