Abstract Because of the serious impact on seismic performance, joint connection form becomes a critical problem in prefabricated building. Built dry connection, this paper proposes detachable and recyclable bolt-steel plate design for fabricated structure. Compared to cast-in-situ method, biggest advantage proposed scheme lies convenient construction. The construction process shows that devices...

A series of experiments were carried out for developing a paint coating removal method high-strength bolted joints in steel bridges. The paint-coated joint specimens heated to the target temperature 200 °C by using sheet-type ceramic heater. maximum could be controlled within 10% value. was easily removed general tools after heating. behaviour bolts with thermal expansion and shrinkage monitore...

With the increasing complexity of engineering geological conditions, problem tensile-shear failure bolts is becoming more serious. Accurate modelling performance bolted rough joints subjected to load essential for support design. In this paper, based on theoretical criteria bolt failure, mechanical model Pile element in FLAC3D program modified, and accuracy modified verified by numerical experi...
