In this study, dynamic bearing capacity of adjacent shallow strip foundations located on sandy soil was examined using a numerical finite difference modeling, FLAC. The behavioral interference of shallow strip foundations under different conditions was investigated. The effect of soil strength parameters, geometric characteristics of shallow foundations and cyclic loads at different distance ra...

With the global economic integration, learning foreign languages has been becoming a living behavior in Chinese younger generation. Therefore, more and more schools or language centers grasp this opportunity to use different EFL teaching method for developing their training market. Based on this, it impels new standard of English courses in order to pay great attention to involve the students i...

To evaluate effect of collection technique infused neutrophils localizing to the skin and short-term storage on in vivo cell funcchamber was 0.1 . 0.06, and 0.006 for tion, neutrophils were collected from 53 unstored PB. IFC, and FL cells, respectively. normal subjects by phlebotomy (PB). interOne-day storage substantially decreased mittent flow centrifugation (IFC), or filtrachamber accumulati...

Because of difficulty in inspection and retrofit of foundation in comparison with other elements, the common design philosophy is to avoid any nonlinear deformation in the foundation. This paper shows that by employing controlled foundation nonlinearity, in predetermined sections with arrangements for inspection and retrofit, it is possible to reduce seismic demand on superstructure. Localizing...

This paper discusses static and dynamic response of nanoplate resting on an orthotropic visco-Pasternak foundation based on Eringen’s nonlocal theory. Graphene sheet modeled as nanoplate which is assumed to be orthotropic and viscoelastic. By considering the Mindlin plate theory and viscoelastic Kelvin-Voigt model, equations of motion are derived using Hamilton’s principle which are then solved...

The present study investigate the effects of mechanical properties of the rock layers in the foundation of concrete gravity dam on the seismic response of gravity dam–reservoir –foundation systems. The mutual effects of different domains are considered in the present research. As a case study the biggest section of Shafarud dam in the north of Iran is modeled two dimensionally using ABAQUS soft...
