Due to the commonly eccentric connection on only one angle leg (bolted or welded), additional bending moments are acting member under compression axial force, leading a complex load-carrying behaviour with flexural and/or torsional buckling phenomena. Furthermore, type and size of rotational restraints at member's ends (provided by adjacent structure) significantly influence capacity these memb...

The critical role played by adhesive bonds in lap joints is well known. A good knowledge of the mechanical properties of adhesive bonds in lap joints is a prerequisite to the design and reliable prediction of the performance of these bonded structures. Furthermore, the lap joint may be subject to high-temperature environments in service. Early detection of the degree of thermal degradation in a...

Often unbraced, the stability of steel storage racks may depend solely on the pallet beam to upright connector and on the stiffness of the base plate to floor connection ([1]). This paper presents experimental results from cyclic tests performed on portal beam to upright bolted moment connections intended for cold-formed steel drive-in and drive-through storage racks. In storage racks, portal b...

Bolt connection is an important component in mechanical structure which significantly affects the dynamic property of whole structure. In this paper, a three-dimensional transition interface model contains geometric and physical parameters proposed to bolted joint based on contact analysis. The are used characterize influence area pressure related such as material, roughness, thickness, tighten...

Abstract In the present paper, design of a steel warehouse structure was investigated. After establishing base sections for beams and columns through ultimate resistance buckling strength, an optimization procedure applied to beam-to-column connection. Three types connections were studied: bolted connection with end plate, welded web flange angles. The detailed analysis components performed hel...

Carbon fibre/epoxy composite joints were assembled with Poly-etherether-ketone (PEEK) and Poly-ethylenimine (PEI) films using a co-curing process to prepare single-lap joint specimens. The tested under quasi-static loading conditions at 22 °C 130 fatigue condition. experimental results demonstrated better or comparable structure integrity of the co-cured by PEEK PEI than reference bonded aerosp...
