Based on shear strength reduction finite element method, stability of retaining wall with relieving plate has been analyzed. Due to the structure character of retaining wall with relieving plate, it can be found that fracture surface could hardly cross the triangle area of between lower wall and soleplate, between upper wall and relieving plate, so the second fractured surface occurred at there...

The stability evaluation of the slope commonly uses limit equilibrium methods, for example, Fellenius’ method in Japan. The limit equilibrium methods have two limitations. (1) It is necessary to divide the sliding mass into slices, and to set up some additional equations to make the problem statically determinate. (2) It is necessary to search sliding surface with a minimum safety factor. Shear...

In this paper, a modified shear strength reduction method (MSSR) and its optimization variant (OPT-MSSR) are suggested. The idea of MSSR is to approximate the standard be more stable rigorous from numerical point view. consists simplified associated elasto-plastic model completed by depending on dilatancy angle. Three Davis' modifications suggested Tschuchnigg et al. (2015) interpreted as speci...

b = a length L c = the cohesion intercept M L T Ip = the plasticity index P = a force M L T u = the pore fluid pressure ML T θ = an angle Angle μ1 = shear strength reduction factor related to time effects μ2 = shear strength reduction factor related to fissuring σ = the normal stress on a plane M L T τ = the shearing stress on a plane M L T φ = the angle of internal friction Angle ψ = an angle ...

Nine restrained T-beams were tested in a study of the negative moment region shear strength of lightly reinforced concrete T-beams. Variables included the longitudinal reinforcement ratio p, (0.47 percent and 0. 70 percent) and the nominal stirrup strength (0 to 84 psi [0 to 0.60 MPa]). The test results are compared with the shear provisions of "Building Code Requirements for Reinforced Concret...

statement of the problem: porcelain laminate veneer is an esthetic restoration used as an alternative to full veneer crowns and requires minimal tooth preparation. in restoration with porcelain laminate veneers, both the longevity of the laminate and conservation of the sound tooth structure are imperative. purpose: the present study aimed to investigate the shear bond strength of porcelain lam...

structural sandwich beams are widely used because of their high specific stiffness and strength, noise reduction, thermal insulation and impact energy absorption characteristics. conventional manufacturing method of composite sandwich structures is completed by a separate adhesive joining stage by which the composite faces are joined to the core. in this investigation, liquid phase sintering in...

objectives: a reduction in bond strength of composite to bleached enamel has been reported immediately after bleaching treatment. application of some antioxidant agents may decrease the adverse effects of whitening agents on bond strength and enhance composite bond to enamel. this study aimed to assess the effect of green tea, sodium ascorbate, sage and grape seed extract on bond strength of co...
