tehran shomal highway passes through alborz mountains with a tunnel length of 6400 meters. there are two main tunnels. a full three-dimensional (3d) numerical analysis coupled with elasto-plastic material models was conducted on the inclined access tunnel. bending moment, axial force and the lining displacements due to the internal forces applied on the shotcrete lining are calculated. axial fo...

In this paper the geometrical relationship of the folds which exist in the Folded Zagros Mountains, including Asef Mountain (northern Iran), were studied. The southern and western zones of the Zagros Mountains are called the Folded Zagros. These zones extend approximately 1,375 km in length with a width ranging from 120 to 250 km. Asef Mountain is located in northern Shiraz (from northern Sarda...

Money transfer through third-party mobile payment platforms has become common nowadays in western countries. While developing countries, the adoption of channels still at infancy stage. The current study based on diffusion innovation theory investigates antecedents intention to use trust's mediating role. survey method was used collect data from 250 consumers using payments services JazzCash an...

The present investigation is concerned with the deformation of thermoporoelastic half space with incompressible fluid as a result of inclined load of arbitrary orientation. The inclined load is assumed to be linear combination of normal load and tangential load. The Laplace and Fourier transform technique are used to solve the problem. The concentrated force, uniformly distributed force and a m...

In this paper, the free convective heat transfer of nanofluids in a square cavity is simulated using numerical method. The angle could be changed horizontal axis from 0 to 90 degrees. exposed under constant magnetic field. Two opposite walls are cold and warm, rest insulated. On hot wall, there two fins with same wall temperature. equations were discretized by finite volume method (FVM) then so...

limitations in the design method used for the support systems of urban buildings make them vulnerable to damage by adjacent excavations. this paper examines a traditional system used to support excavation sites and adjacent buildings in which inclined struts are connected to the wall or foundation of the adjacent building. this method can be considered to be a type of shoring or underpinning. t...
