Abstract

Presently there are two cold-formed steel structural design documents in North America, i.e., in the USA, the Specification for the Design of Cold-Formed Steel Structural Members, published by the American Iron and Steel Institute (AISI 1996) and in Canada, the Standard for Cold-formed Steel Structural Members, published by the Canadian Standards Association (CSA 1994). The bearing strength of bolted connections is treated differently in these two design documents. The North American Specification for the Design of Cold-formed Steel Structural Members (NAS 2001) contains a new approach for bearing of bolted connections. This approach is similar to the current S136 Standard (CSA 1994) approach, which has been considered in this investigation. Contained in this paper are the test results of single and double shear cold-formed steel bolted connections failing in bearing, with and without washers. The test data were compared with the methods for determining the bearing strength of cold-formed steel bolted connections currently used in the AISI Specification (AISI 1996), the S136 Standard (CSA 1994), and the North American Specification (NAS 2001).

Testing of Bolted Cold-formed Steel Connections in Bearing (With and Without Washers)

Presently there are two cold-formed steel structural design documents in North America, i.e., in the USA, the Specification for the Design of Cold-Formed Steel Structural Members, published by the American Iron and Steel Institute (AISI 1996) and in Canada, the Standard for Cold-formed Steel Structural Members, published by the Canadian Standards Association (CSA 1994). The bearing strength of bolted connections is treated differently in these two design documents. The North American Specification for the Design of Cold-formed Steel Structural Members (NAS 2001) contains a new approach for bearing of bolted connections. This approach is similar to the current S136 Standard (CSA 1994) approach, which has been considered in this investigation. Contained in this paper are the test results of single and double shear cold-formed steel bolted connections failing in bearing, with and without washers.
