The failure assessment diagram (FAD) has now been widely accepted and used for the assessment of defects found in metallic structures. In BS7910 (2005), the use of this method for offshore structures has been validated for a range of joint geometries. But these validations are only applicable for circular hollow section (CHS) welded joints. For rectangular or square hollow section (RHS or SHS) joints, there are very few references available in the literature. In this paper, systematic investigations have been carried out for the validation and verification of the FAD curves for SHS T-joints. FAD curves for a wide range of welded SHS T-joints containing surface cracks have been established using the fracture mechanics data generated from the finite element analyses. The range of β ratio of these joints is from 0.3 to 0.8. Therefore, the failure mode is constrained in the chord face yielding. The influence of residual stresses on the plastic collapse load and the FAD curves has also been analyzed. The reduction factor used to calculate the plastic collapse load of the SHS T-joints containing cracks have been quantitatively examined, and the use of the BS7910 (2005) Level 2A FAD for SHS joints containing surface cracks has been validated accordingly.

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.
