RISInexpensive Strengthening Technique for Partially Loaded Reinforced Concrete Beams: Experimental Study
Publisher: American Society of Civil Engineers
Nonlinear Vibrations of a Thin Plate Under Simultaneous Internal and External Resonances
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamic behavior of a rectangular thin plate under parametric and external excitations is investigated. The motion of the thin plate is modeled by coupled second-order nonlinear ordinary ...
Numerical Modeling of Shear Strengthened Reinforced Concrete Beams Using Different Systems
Publisher: American Society of Civil Engineers
Abstract: This research aims at creating finite-element models for fiber-reinforced polymer (FRP) shear strengthened concrete beams. It is inspired by the fact that the determination of the structural behavior of shear strengthened ...
Management of Radioactive Waste in Libya: Case Study
Publisher: American Society of Civil Engineers
Abstract: Libya has dealt with a high number of radioactive sources since the end of the 1950s when oil exploration processes started. Today, there are more than 125 facilities in the country tha use radioactive sources for medical ...
Discrete-Element Method Simulations of the Seismic Response of Flexible Retaining Walls
Publisher: ASCE
Abstract: In this study, an analysis of soil–retaining wall dynamic interaction is conducted using three-dimensional discrete-element method (DEM) simulations. Soil grains are treated as rigid spherical particles that are allowed ...
Simplified Second-Order Analysis of Slender FRP-Reinforced Concrete Columns Using the Nominal Curvature Method
Publisher: American Society of Civil Engineers
Abstract: The nominal curvature method is one of the simplified methods for the second-order analysis of steel-RC columns in design codes. The two parameters that are important in the application of this method are the total curvature ...
Pore-Scale Modeling of Fine-Particle Migration in Granular Filters
Publisher: American Society of Civil Engineers
Abstract: Fine-particle migration and associated internal erosion are major concerns for dam safety. Granular filters are used to prevent fine-particle migration, and several empirical models have been introduced for the design of ...
Some Aspects of the Impact of Multidirectional Shaking on Liquefaction of Level and Sloping Granular Deposits
Publisher: American Society of Civil Engineers
Abstract: A very limited number of computational studies have been presented for the analysis of the response of saturated granular soils to multidirectional shaking despite it being the realistic mode of loading that resembles an ...
Multiscale Modeling of Flood-Induced Piping in River Levees
Publisher: American Society of Civil Engineers
Abstract: A three-dimensional transient fully coupled fluid-particle model is utilized to simulate flood-induced piping under river levees and taking into account the effects of soil-fluid-structure interactions. The porous soil ...
Discrete-Element Method Simulations of the Response of Soil-Foundation-Structure Systems to Multidirectional Seismic Motion
Publisher: American Society of Civil Engineers
Abstract: In this study, a three-dimensional microscale framework utilizing the discrete-element method (DEM) is presented to analyze the seismic response of soil-foundation-structure systems subjected to three-directional base ...
