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...

Abstract The aim of this research is to provide an alternative for the conventional design beam‐to‐column connections in building structures. new performed by means Structural Topological Optimization and executed additive manufacturing with steel. Regarding methodology, joint that would be manufactured methods (i.e. welded bolted plates) modelled finite elements first place. Its behavior obtai...

Web of plate girders in bridges are usually reinforced by welded transverse stiffeners inorder to improve their shear capacity. Due to problems associated with field welding and fatigue,welded stiffeners are not suitable for retrofitting existing bridges. Bolted stiffeners are a practicalalternative for strengthening girders that are expected to experience shear stresses in excess of theirdesig...

BOG (Boil off Gas) compressor deals with the gas evaporated from the LNG storage tank. Its working temperature is lower than-120℃. There are two types of starting process for BOG compressor: Direct Starting and No-load Starting. During the starting process, the temperature on cylinder will change rapidly and result in additional thermal stress to some parts on the cylinder, especially to the bo...

It has been widely recognized that there are influences of static friction characteristics in a bolted joint on pre-tightening and service reliability. This study proposed coefficient model surfaces based the modified three-dimensional fractal model. A method measuring was investigated to verify accuracy The results showed calculated value measured experiment highly matched. Furthermore, influe...

Advanced hybrid joints, which incorporate a specially designed array of macro-scale pins that provide mechanical interlocking reinforcement, have been developed in order to address the challenges associated with joining fibre reinforced composites to metals. In the present work, important joint characteristics including strength, mechanical fatigue, damage tolerance and durability have been stu...
