Seismic stability of reinforced-soil wall by pseudo-dynamic method
Determination of the internal stability of reinforced soil walls under earthquake conditions is an important part of seismic design. The horizontal method of slices is used for determining internal stability or for tieback analysis of the reinforced soil wall. A pseudo-dynamic method is adopted in the present analysis, which considers the effect of phase difference in both the shear and primary...
متن کاملBidirectional Shaking Table Tests of a One-fourth Scale Reinforced Concrete Space Frame
Shaking table tests on the 1/4th-scale three-story reinforced concrete frames were carried out to investigate the effects of bidirectional earthquake motions on overall nonlinear response of reinforced concrete frame buildings. Two identical models were constructed and one was subjected to bidirectional horizontal earthquake motions and the other was subjected to unidirectional one. A series of...
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 کاملFrequency Response Analysis of Reinforced- Soil Retaining Walls with Polymeric Strips
Few studies have been conducted on polymeric strip and the behavior of soil retaining walls. This paper will present the effect of frequency on the dynamic behavior of reinforced soil retaining walls with polymeric strips. The frequency content describes how the amplitude of a ground motion is distributed among different frequencies. Since the frequency content of an earthquake motion will stro...
متن کاملSimplified Procedure to Evaluate Earthquake-induced Residual Displacement of Geosynthetic Reinforced Soil Retaining Walls
Based on a series of shaking table model tests, it was found that the eŠects of 1) subsoil and backˆll deformation, 2) failure plane formation in backˆll, and 3) pullout resistance mobilized by the reinforcements on the seismic behaviors of the geosynthetic reinforced soil retaining walls (GRS walls) were signiˆcant. These eŠects cannot be taken into account in the conventional pseudo-static ba...
