Abstract Currently, research on an energy-saving device only focuses the effective operation of this device. Structural assessment is needed to evaluate reliability interceptor in conditions. In study, 25 mm thick interceptors are evaluated using finite element method find optimized position bolt connector. The simulation shows that a smaller size connector leads higher maximum stress intercept...

Joint connection methods, such as shear key and loop bar, improve the structural performance of precast concrete structures; consequently, there is usually decreased workability or constructional efficiency. This paper proposes a high-efficiency skewed pipe shear connector. To resist shear and pull-out forces, the proposed connectors are placed diagonally between precast concrete segments and a...

Determination of the local interlaminar stress distribution in a laminate with a bolt-filled hole is helpful for optimal bolted joint design, due to the three-dimensional (3D) nature of the stress field near the bolt hole. A new interlaminar stress distribution phenomenon induced by the bolt-head and clamp-up load, which occurs in a filled-hole composite laminate, is investigated. In order to e...

This paper aims to study the mechanical behaviour and failure mode of Al 2024-T3 in double-lap bolted joints. To accomplish this, the effect of geometric parameters was investigated in both configurations of single and double fasteners. Using ABAQUS/Standard, a three-dimensional finite element model was developed and verified against the experimental results of the joints loaded in tension. In ...

Three types of shear stud arrangement, respectively featuring an orthogonal, a radial and a critical perimeter pattern, were evaluated numerically. A numerical investigation was conducted using the finite element software ABAQUS to evaluate their ability to resist punching shear in a flat plate. The finite element analysis here is an application of the nonlinear analysis of reinforced concrete ...

The main challenge for realizing competitive hybrid steel-FRP structures, such as bridges, carparks, is to make the steel and FRP components work together. In this study shear resistance, stiffness ductility of three types demountable bolted connectors are examined. Two blind-bolted M20 a novel, injected steel-reinforced resin (SRR) connection selected perform push-out experiments in web-core d...

OBJECTIVE To analyze the in vitro mechanical strength of the DHS-AF(®). METHODS We evaluated the in vitro resistance of a sliding bolt modified by the addition of a connector system, DHS-AF(®). RESULTS The changes performed by the authors allow the exchange by the surgeon of the sliding bolt without the need to remove the plate and disassemble the entire device to reposition it properly. We...

Shear connectors in composite beam are used to ensure proper connection between concrete slab and steel beam. Headed stud shear the types most commonly constructions. Despite its popularity, this type of has presented some drawbacks, notably installation technique which demands many requirements. Recently, several have been developed as an alternative studs. The aim present paper is a study new...
