An analytical approximate solution is developed for predicting the thermal resistance of bolted joints between two square plates . of the same material but different thicknesses. The plates are assumed to have perfectly flat and smooth surfaces, and they are joined by a bolted connection at the center of the square, forming a concentric annular contact region at the interface. The entire surfac...

in this research, the influence of bolt preload on the fatigue strength of 2024-t3 aluminium alloy double lap bolted joints has been studied experimentally and numerically. to do so, three sets of the specimens were prepared and each of them subjected to tightening torque of 1,2.5 and 5 n-m and then fatigue tests were conducted under various cyclic axial load levels. in the numerical method, th...

Background The addition of new material technologies in mining, energy, construction and aerospace industry, among others, have requested the concentration of several researches to guide and enhance the implementation of the same. Due to the development of these new materials, a number of researches have been developed to improve the materials adhesion, which traditionally use bolted or riveted...

A literature review has been carried out relating to the damage and fracture behaviour of composite laminates based on woven fabric reinforcement containing a stress raiser in the form of either a circular hole or of a mechanically fastened joint – the tensile failure modes in these two types of problem are very similar. Closed form and finite element based approaches that enable the stress dis...

In the last two decades, high-rise timber buildings have been built using glulam truss system, even with limited openings. Moment-resisting frames (MRTF) semi-rigid beam-to-column connections can be an architecture-friendly way to provide a load-carrying system vertical and horizontal loads for buildings. these structures, of adequate ductility are crucial ensure robustness energy dissipation. ...

Structures subjected to seismic forces must have adequate strength and stiffness to control inter storey drift in order to prevent damage to structural and nonstructural elements during excitations. Linked column concept for steel structures was proposed by Peter Dusicka et.al(2009) with the objective of utilizing replaceable components that are strategically placed to protect the gravity load ...

The behaviour of beam-column joint plays an important role in the response of a steel moment resisting framed structure especially under seismic excitation. Semi rigid connections like bolted joints, allow better energy dissipation and provide good response under lateral loads. In this paper the ductility and energy dissipation characteristics of semi rigid bolted connections using double web a...
