Effects of spot-weld spacing on the axial crushing of closed-hat section members

摘要

This paper describes an experimental investigation into the effects of the spacing of spot welds on the collapse behaviour of axially crushed cold formed steel closed-hat section members. Suitable spacing requirements for spot welds to ensure stable collapse procedures are examined and proposals are made for minimum spacing distances. The effects of spot weld spacing on the collapse loads and subsequent crushing behaviour are examined.
