Seismic Analysis of Retaining Walls within Plasticity Framework
Aseismic design of gravity wall still is a more difficult issue. The reason stems from the complexity of the problem which requires skills in soil mechanics, foundation engineering, soil-structure interaction along with knowledge of structure dynamics. Designing seismic gravity retaining structures deals with both kinematic interaction and inertial interaction but almost seismic building code n...
متن کاملseismic analysis of lateral earth pressure and retaining walls
eart pressure problems are encountered in retaining walls, bulkheads, sheeting and bracing in cuts,culverts, tunnels, and cofferdams. in many cases, the lateral pressure is determined by use of classical earth pressure theories, such as coulomb's, where the equilibrium conditions of a failure wedge of soil is considered. excessive dynamic lateral earth pressure on retaining structures resu...
متن کاملResponse and Modeling of Cantilever Retaining Walls Subjected to Seismic Motions
A series of nonlinear, explicit finite difference analyses were performed to determine the dynamic response of a cantilever retaining wall subjected to earthquake motions. This article outlines the calibration and validation of the numerical model used in the analyses and comparisons are presented between the results from the finite difference analyses and results from simplified techniques for...
متن کاملcalculation of static lateral thrust and its application point on rigid retaining walls in layered backfill
in this paper, based on soil plasticity and pseudo-static methods, necessary equations have been derived for determination of total active thrusts due to layered backfill on rigid retaining walls using limit equilibrium approach. for this purpose, the reaction force applied on the failed wedge due to granular backfill has been determined using kotter’s equations. the total lateral thrust and th...
متن کاملSimulation of Nonlinear Seismic Response of Reinforced Concrete Structural Walls
In this study the performance of three macro-models in predicting the nonlinear response of different walls is investigated. The macro-models used are: Equivalent Beam Model, Multiple Vertical Line Element Model and a shear panel model developed by Massone et al. (2006). The walls are classified as slender, intermediate, and squat walls according to their shear-span ratio. First, three single w...
