Due to the problems of potential corrosion and thermal expansion differences between traditional metal connecting pieces and carbon fiber poles, it is difficult for them to meet the operating requirements of truss structures in the environment of stratosphere. Based on the large scale composite space truss structure of stratosphere aerostats, the carbon fiber flange connection joints were studi...

welding produces residual stresses and distortion, having detrimental effect on structure integrity and service performance of the welded pipe joints. this paper investigates residual stresses and distortion during gas metal arc welding (gmaw) of pipes of schedule 40 and 60, nominal diameter 100mm and 200mm and thickness 8mm and 10mm with ansi flanges of class 300#. welding parameters including...

This paper presents cyclic behaviour of bolted and hybrid–combined bonded fibre reinforced polymer (FRP) beam-to-column joints between I-shaped members using steel FRP cleats. Five full-scale tests are carried out to study moment-rotation behaviour, response, failure patterns. The test parameters include position cleat (flange or combined web flange), fastening method (bolting hybrid–combining ...

The industrial process adds to engineering wood products features absent in solid wood, with homogeneous structure and reduced defects, improved physical and mechanical properties, bio-deterioration, resistance and better dimensional stability, improving quality and increasing the reliability of structures wood. These features combined with using fast-growing trees, make them environmentally ec...

Pipe joints have been widely utilized in industrial plants, where dynamic load of vibration is considerably harmful for sealing performance. However, there is a lock of design codes and experimental procedures developed for vibration testing of pipe joints. This paper proposes an experimental setup for testing of pipe joints, which use metal gaskets, in vibratory conditions. Also, a flexible pi...

The present contribution is the first research reporting full penetration HLAW joints in 15 mm thick EH36 steel butt T-welds with square grooves on 2F welding position by single-sided welding. effects of parameters were investigated to increase quality joints. Conditions leading defect-free welds fulfilling naval regulations includes a laser power 12.5 kW, speed 1.6 m/min and vertical offset di...
