The earthquake-induced displacement of sloping soil mass is an important indicator co-seismic landslide initiation. In this paper, improved Newmark model that considers the accumulation dynamic pore water pressure (DPWP) in caused by both vertical and horizontal ground motions proposed. can quantitatively describe changes seismic yield acceleration near-saturated infinite slopes. Three differen...

Dynamic slope stability in open-pit mines still remains a challenging task in the computational mining design. Earthquake and blasting are two significant sources of dynamic loads that can cause many damages to open-pit mines in active seismic areas and during exploitation cycles. In this work, the effects of earthquake and blasting on the stability of the NW slope of Chadormalu mine are compar...

Study on the seismic behavior of piled rafts and pile groups while the same amount of construction material and excavation is used in their construction, are the main objective of this research. The process where the raft interaction with soil can affect the seismic response and stress distribution is also discussed in the current study. By means, ABAQUS software was applied for the finite elem...

Abstract The present work deals with assessment of earthquake-induced displacement the base restrained retaining walls (RW’s). A detailed and rigorous finite element (FE) investigation has been carried out following shaking table experiments on a scaled-down RW model. FE simulations were performed by conducting several nonlinear time history analyses two-dimensional (2D) plane strain model prot...

in this paper the traditional covering plaster of masonry buildings is supplied with polypropylene and steel fiber to enhance their seismic behavior. the plaster mix proportion is determined by some initial mortar tests. also, one story, single span masonry building specimen plastered with different mortars is tested on a shaking table 8 times under a seismic input and the performance of the sp...

In this paper, we present a mode superposition method for uid-structure interaction problems based on velocity potential and pressure formulation for acoustic uids and displacement formulation for solids. The eeectiveness of the proposed numerical procedure is demonstrated in a test example with seismic ground motion eeects. 1 INTRODUCTION Fluid-structure interaction systems are widely used in ...

the objective of this paper is to present a new method for protecting the lives of residents in catastrophic earthquake failures of unreinforced masonry buildings by introducing some safe rooms within the buildings. the main idea is that occupants can seek refuge within the safe rooms as soon as the earthquake ground motions are felt. the information obtained from the historical ground motions ...
