due to the existence of fibrous materials such as plastic fragments, the strength anisotropy of municipal solid waste (msw) materials is the main source of differences between their mechanical response in direct shear and triaxial apparatus. as an extension of earlier research on the mechanical behavior of msw using a large traixail apparatus, results presented in shariatmadari et al. [1] and k...

In this research in-plane shear Behavior of composite steel-concrete shear walls was investigated considering the Effects of steel plates thickness, spaces between shear studs, shape and type of shear studs and existing of minimum reinforcement in wall section. Several finite element models were analyzed and Numerical results of two models were taken under verification with existent experimenta...

In this research, using the Modified Compression Field Theory (MCFT), a new truss based model is proposed to predict the behavior of reinforced concrete coupling beams with diagonal reinforcement. The model is able to consider the effects of shear and axial forces and bending moment, simultaneously. The proposed model includes a nonlinear shear spring, an axial spring, two inclined truss member...

OF DISSERTATION THE DEVELOPMENT AND IMPLEMENTATION OF SYSTEMS TO STUDY THE PHYSICAL PROPERITES OF TANTALUM TRISULFIDE AND SMALL-MOLECULE ORGANIC SEMICONDUCTORS The charge-density-wave (CDW) material orthorhombic tantalum trisulfide (TaS3) is a quasi-one dimensional material that forms long ribbon shaped crystals, and exhibits unique physical behavior. We have measured the dependence of the hyst...

Off-road cars’ windshields are vulnerable to different types of stones, road debris and pebbles due to common off paved and gravel surfaces in which they drive. Any attempt to design windshield that minimizes injury and death of occupants during a vehicle accident requires a thorough understanding of the mechanical behavior of automotive windshield subjected to foreign object impact loads...

Assuming that the ground anchor is connected with rock–soil of sidewall by a tangential linear spring, load transfer model fully grouted established using spring element method, and analytical solutions displacement, axial force, shear stress distribution in upper lower parallel strata foundation sandwich are given, respectively. Corresponding to above two kinds alternating strata, mechanical b...

coupled -shear walls are one of lateral load resisting systems in high and medium rise reinforced concrete buildings. the lateral structural response is exactly dependents on the shear walls behavior; therefore these elements must response well whenundergodifferent load conditions. the structures located in near-source region behave differently compared to those in near-source sites when subjec...
