Thesis title: Performance of demountable tubular connections formed by composite chord and hollow braces

Supervisors: Luming SHEN , Chao HOU

Thesis abstract:

Recently, bolting system is considered to be the replaceable technique, which allows both excellent structural performance and demountable appearance for composite connections with rectangular sections. Nonetheless, few studies on demountable steel and composite tubular connections were carried out, especially for tubular chord and brace connections. It is expected that the behaviour and mechanism of demountable CFST connections are different from that of welded ones, e.g. failure modes and stiffness. Furthermore, the interaction of bolts, chord and braces are more complicated for circular tubes than rectangular one due to curved surfaces, affecting the performance greatly. Factors including dimension of baseplate, types of blind bolts and spacing between bolts should change the bearing capacity considerably. This project will be based on previous design of demountable composite connections and design rules, to propose a new design with effective engineering characteristics and reduce negative influence on environment caused by steel manufacturing at the same time.
