Abstract:
Various one-side bolts have been developed and applied to facilitate the connection between closed section columns and beams, which are distinguished by compositions, installation methods, tightening mechanisms and bearing mechanisms. 22 types of one-side bolts are investigated, which are divided into 2 main categories and 5 sub-categories according to their tightening mechanisms. The constitutes, tightening mechanisms and installation methods of each one-side bolt are introduced in detail, and the development sequences and mechanical performance of partial important one-side bolts are sorted out. The quantitative comparison of mechanical properties between one-side bolts and high strength bolts shows that only several one-side bolts have comparative mechanical performance as high-strength bolts. On the basis of review, the prospects on the development and research directions of one-side bolts are proposed to provide reference for the engineering practice of one-side bolts in building structures.
