introduction: failures might occur at metal‒porcelain interfaces as a problem with metal‒ceramic restorations even with the application of airborne-particle abrasion technique. this study was undertaken to evaluate the effect of nd:yag laser treatment on the bond strength of porcelain fused to metal. methods: twenty-four cylindrical specimens (4 mm in diameter and 4 mm in height) were made of ...
The problem of shear is not yet fully understood due to involvement of number of parameters. Designers are extra careful about shear, especially in beams and consequently higher safety factors are used in shear design. Several equations are available in literature to determine the shear capacity of beams, i.e. ACI equation, Zsutty equation and KIM & White equation. To verify the application of ...
Steel-concrete-steel (SCS) sandwich panels are composed of two steel plates with low thicknesses and high densities and strengths and one thick layer between both plates with low strength and density known as core that is composed of concrete. Cohesive material-epoxy resin or shear connectors are usually used to connect the plates to the concrete core. SCS sandwich composites are being develope...
Data collected from shake table tests of two, approximately one-third scale, two story flat plate frames utilizing shear reinforcement, as well as data from prior tests, were evaluated to assess the inter-story drift ratios when punching failures occur for reinforced concrete and post-tensioned slab-column connections with and without shear reinforcement. The drift ratios at punching for the sh...
Fine-grained materials of Clayey Loess deposits of Gorgan region were mixed with sand dune in the lab with various rations and their shear behavior was measured and evaluated by direct shear test. The result of the study showed that the increase of fine-grained clay in sand dune was directly related to the adhesion force and inversely to the internal friction angle. The increase or reduction in...
The shear strength parameters—the cohesion and the internal friction angle—are important parameters in calculating of soil, which is a mechanical property reflecting resistance soil to shearing. This article embeds angle results sandy loam measured using direct test relying on drawing Mohr–Coulomb line. Beside parameters, this contains colour tested at different moisture contents, spectrophotom...
