TESTS ON 10.9 BOLTS UNDER COMBINED TENSION AND SHEAR

Anne Katherine Kawohl, Jörg Lange

Abstract


Prior investigations of the load-bearing capacity of bolts during fire have shown differing behaviour between bolts that have been loaded by shear or by tensile loads. A combination of the two loads has not yet been examined under fire conditions. This paper describes a series of tests on high-strength bolts of property class 10.9 both during and after fire under a combined shear and tensile load.
