This article presents a comprehensive review of existing North American research on weld effective lengths for hollow structural section (HSS) connections. Data from 393 experiments and finite-element analyses is analyzed to determine the inherent reliability index (β+) of existing and proposed AISC 360 formulae for weld effective properties in axially loaded rectangular hollow section (RHS) T-, Y- and X-connections, RHS gapped and overlapped K-connections, RHS moment-loaded T-connections, and circular hollow section T-, Y- and X-connections, when used in conjunction with CSA S16-19 Clause 13.13.4.3(a) for design of welds to the ends of HSS branches. Modifications to the formulae are proposed to achieve β+ ≥ 4.0 (the target reliability index for connectors according to Annex B.4 of CSA S16-19), and recommendations are made to facilitate a “fit-for-purpose” design approach for welds to HSS. These are proposed for the next scheduled revision of CSA W59.

Chord Member

In all truss-type welded hollow structural section connection design procedures, the chord member is assumed continuous on both sides of the branch. New limits of applicability have recently been advocated, which specify minimum end distances from an open chord end to achieve the full connection strength. To investigate their suitability for rectangular hollow section (RHS) connections, an experimental program consisting of 12 RHS-to-RHS X-connections subject to branch axial compression was undertaken. For connections near a chord end, a modified yield line mechanism controlled. A proposed analytical model is derived, and by evaluating against the experimental results, is shown to accurately predict the yield loads. An EN 1993-1-8 amendment, transcribed from circular hollow section connections, is deemed excessively conservative, and a closed-form solution for the end distance, presented herein, is recommended for use with RHS connections. Alternatively, providing a cap plate is determined to be an effective stiffening method.

Circular Hollow Section

Spun pile is one of the types of piles are widely used in the world construction, for example in building and bridge. Spun pile is a prestressed concrete pile with circular hollow section. This paper provides an overview of the research development of spun pile, starting from 80's until now. This overview is related to methods of increasing the strength and reliability of spun pile due to earthquake loads, either by modifying the longitudinal reinforcement and confinement. In addition, this paper also discusses about the failure patterns of spun pile due to seismic loads. Finally, this paper can be a reference for understanding the scope of the research topics that have been done by researchers. Thus, by this overview can be obtained new idea for the next research to improve the performance of spun pile carry seismic loads.
