Strength Tests on Bolted Connections Using High-Strength Steels (HSS Steels) as aBase Material

摘要

The results of a series of tests on bolted connections using high-strength steel(HSS) as a base material are presented and analyzed in the report. The base material used was HSF 640 which has a yield stress of 640 MPa. The tests studied bearing resistance, net section failure and the block shear failure mode. The test results have been analyzed according to the Finnish specification for steel structures B7, the Swedish specification BSK, the NKB-specification and according to the Eurocode 3. The block shear failure mode has been analyzed according to the American LRFD-specification. The aim of the study has been to provide experimental test results to allow the development of reliable calculation methods for connections using HSS steels in different types of steel structures.
