This article presents research on the bearing capacity and methods of calculating reinforced concrete beams shear without internal reinforcement, which are strengthened with a composite FRCM system. The test samples were divided into two series: first series—control, in variable parameter was span (a/d = 2, a/d 1.5, 1); second series—reinforced by system, load, at different load levels. method ...

PURPOSE A three-dimensional finite element analysis was conducted to evaluate and compare the stress distribution around two prosthesis-implant systems, in which implants were arranged in either a straight-line or an intrabone offset configuration. MATERIALS AND METHODS The systems were modeled with three titanium implants placed in the posterior mandible following a straight line along the b...

The solution of timber-to-concrete composite (TCC) floors represents a well-established construction technique, which is consistently used for both the retrofitting existing timber and realization new diaphragms. success TCC relies on intrinsic effectiveness in increasing in-plane (for lateral loads) out-of-plane gravity performance floors. As widespread retrofit intervention, it common to use ...

Abstract The work at hand proposes a method for assessing, under reasonable hypotheses from an engineering perspective, the failure envelope of pile group subjected to generalized loading conditions involving vertical and lateral force along with moment. Following different assumptions increasing complexity, simple closed-form expression, which is however capable considering also strong depende...

The creeping of the beetle Tetraopes tetraopthalmus during negatively geotropic orientation shows the angles of orientation (theta) on a surface inclined at alpha degrees to the horizontal to be proportional to sin alpha. The direction of orientation easily suffers temporary reversal to positive as result of handling. Mechanical stability during upward progression should be just possible when K...

This paper proposes a method to measure the inclined angle of an objective image based on the most frequent edge direction. This paper also describes a relation between the measured inclined angles by the proposal method and the visual inclined angles. An edge direction is changed according to the inclination of an objective image. The most frequent edge direction is supposed to show the global...
