Resumo An experimental and numerical investigation was conducted into the factors that interfere in the shear strength of the concrete-concrete interface in structures composed of double lattice panels subjected to direct shear stress. The experimental program consisted of testing 26 direct shear models with varying widths of concrete fi lling of 7 cm, 9 cm and 13 cm, with smooth and rough inte...

Associations between 3 commercially available genetic marker panels (GeneSTAR Quality Grade, GeneSTAR Tenderness, and Igenity Tender-GENE) and quantitative beef traits were validated by the US National Beef Cattle Evaluation Consortium. Validation was interpreted to be the independent confirmation of the associations between genetic tests and phenotypes, as claimed by the commercial genotyping ...

Pressure sensitive mounting tapes provide a quick and effective fastening method compared to most mechanical joining techniques. Due to the viscoelastic nature of pressure sensitive adhesives their response to mechanical and climatic stress in terms of durability is different from most structural adhesives. While the feature of compensating differences in thermal expansion of bonded members and...

This masonry research investigated the differences in the static and dynamic stiffness for the seismic range of loads and frequencies for a pressed clay masonry wythe. The effective stiffness has been defined in Newtonian physics and Damage Mechanics. This research used the concept of measured stiffness defined as the measured stress field divided by the measured strain field. A two-part test r...

Typical insulated precast concrete sandwich panel (PCSP) systems are composed of two wythes separated by a layer insulation. The structural behavior PCSP heavily depends on elements between known as connectors, which ensure they work whole. Double shear tests were carried out 58 specimens reinforced with basalt fiber-reinforced polymer (BFRP) connectors; failure modes, load displacement curves ...

Mass ply panel (MPP) is a new mass timber product that was recently introduced for structural applications in buildings. Although there have been several studies on characterizing the mechanical properties and performance of MPP, lack understanding regarding in-plane shear panels. More intensive should be done MPP to provide comprehensive its behavior. This paper presents an experimental study ...
