Abstract
For large-span single-layer reticulated structures, the main recent challenge is to develop a new joint that can provide the structure with enough stiffness, whilst also meeting various important requirements, such as easy assembly on the construction site. In this paper, a new joint, named the bolt-column-plate (BCP) joint, is developed, and a three-dimensional FE model of the joint is established. Combined with theoretical analysis, the mechanical performance of the joint is investigated, under both static and quasi-static loads. A parametric study is conducted to i) Obtain the stiffness, strength, rotation behavior and failure mode of the joint under different static load conditions, including axial pressure, axial tension, pure bending, bending with axial force, eccentric pressure and eccentric tension; ii) Obtain the M-φ hysteresis curves of the joint under quasi-static loads, and investigate hysteretic performance, energy dissipation and ductility; iii) Investigate the load-transferring mechanism of the joint under static and quasi-static load conditions. Finally, the data provided by the simulations proves that the new joint has good mechanical performance, under both static and quasi-static loads. This provides guidance for the practical application of this kind of joint system in real structures.
