Reinforced Concrete (RC) deep beams are commonly used in structural design to transfer vertical loads when there is a vertical discontinuity in the load path. Due to their deep geometry, the force distribution within the RC deep beams is very different than the RC shallow beams. There are some strut and tie model (STM) already been developed for RC deep beams. However, most of these models are ...

although bearing capacity of footings on top of slopes under monotonic loadings have been investigated widely so far, safety and bearing capacity of these structures against repeated dynamic loads have not been considered well enough. in this paper, lower bound dynamic shakedown theorem in its numerical form has been employed to firstly obtain bearing capacity of strip footings on top of slopes...

objective: endothelium is a selective and permeable membrane for transferring nutrients and vital components to arterial wall. endothelial damage might lead to altered biological function of endothelium and clinical consequences such as atherosclerosis. blood pressure pulse always exerts circumferential tension to the arterial wall. hence, such tension together with other loads, play important ...

PURPOSE The purpose of this study was to compare the mechanical stability of three types of plate systems for opening wedge high tibial osteotomy. MATERIALS AND METHODS Forty-eight fresh frozen porcine tibia specimens were assigned to three different fixation device groups: Aescular group (16 specimens) was fixed with Aescular plates; Puddu group (16 specimens) with a Puddu plate, and TomoFix...

OBJECTIVE To determine if an interlocking bolt would limit subsidence of the biological fixation universal hip (BFX(®)) femoral stem under cyclic loading and enhance construct stiffness, yield, and failure properties. STUDY DESIGN Ex vivo biomechanical study. ANIMALS Cadaveric canine femora (10 pairs). METHODS Paired femora implanted with a traditional stem or an interlocking stem (constr...

Because of it’s economy, high strength-to-weight ratio and stiffness-to-weight ratio, wood can compete with steel and reinforced concrete as a construction material in a market with an increasing demand for large structures such as community buildings, gymnasiums, schools and bridges. However, continued acceptance or expansion in this market, particularly in high wind or seismic areas, depends ...
