Abstract In the construction of concrete bridges, lighter dead load decks can significantly reduce number or size substructure members, such as girders, piers and foundations. Although, arch (ADs) ensure superior carrying capacity have longer span length than flat (FDs), relatively minute studies was performed on manufactured shape to maximize performance. previous study, a precast reinforced (...

Abstract This paper presents the results of a theoretical-numerical study laterally-restrained thin-walled steel rectangular hollow flange beams subjected to bending, shear and bending interaction. Finite element analyses were carried out by using ANSYS software, validated previous experimental tests. Furthermore, effect intermediate stiffeners was investigated, where improvement percentage in ...

This paper describes an experimental investigation into the seismic behavior and efficiency of steel frames with special bracing infills. Cold formed steel studs (CFSS), typically used in nonstructural partition walls, were studied to determine if they could be used to laterally restrain braces against buckling and thus enhance their seismic performance. Four specimens were ductile designed and...

background: considering the negative consequences of using physical restraints, we conducted this study to identify patients who are more frequently restrained in a psychiatric emergency ward as an initial step to limit the use of restraint to the minimum possible. methods: this was a retrospective case control study conducted in iran psychiatric hospital in tehran, iran. we reviewed the files ...

‎For any integer $kgeq 1$‎, ‎a set $S$ of vertices in a graph $G=(V,E)$ is a $k$-‎tuple total dominating set of $G$ if any vertex‎ ‎of $G$ is adjacent to at least $k$ vertices in $S$‎, ‎and any vertex‎ ‎of $V-S$ is adjacent to at least $k$ vertices in $V-S$‎. ‎The minimum number of vertices of such a set‎ ‎in $G$ we call the $k$-tuple total restrained domination number of $G$‎. ‎The maximum num...

This article presents a study of the behavior hybrid steel beams I-profile cross section subjected to bending. Numerical models finite elements were developed and validated in ABAQUS software. In models, lateral buckling with torsion was disregarded, since beam will be laterally restrained, so that only local instabilities are present thus evaluated. Analyses divided into two stages: first, ela...

Buckling restrained braced frames (BRBFs) for seismic load resistance have been widely used in recent years. One of the key requirements for a buckling restrained brace is to sustain large plastic deformations under severe ground motions. The core of a buckling restrained brace is prone to fatigue fracture under cyclic loading. The earthquake induced fracture type of the core plate in a bucklin...

The first step in the design of plate girder is to estimate the self-weight of it. Although empirical formulae for the same are available, the level of their accuracy (underestimate or overestimate) with respect to actual self-weight is not known. In this paper, optimized sections are obtained for different spans subjected to different live load carrying capacities and self-weights are estimate...

Background: Considering the negative consequences of using physical restraints, we conducted this study to identify patients who are more frequently restrained in a psychiatric emergency ward as an initial step to limit the use of restraint to the minimum possible.   Methods: This was a retrospective case control study conducted in Iran Psychiatric Hospital in Tehran, Iran. We reviewed the f...
