Experimental Study of High-Strength Bolts under Combined Tension and Shear During and After Fire
Abstract
Experimental studies on high-strength bolts which included both tests under tension and shear show deviating reduction of strength with rising temperatures depending on whether the bolts were loaded by tension or shear. In this paper an experimental study on high-strength bolts of the property class 10.9 under a combination of both tension and shear will be presented. Tests were carried out both under fire conditions and at ambient temperature on bolts first heated to a specified temperature and then cooled slowly to establish the post-fire performance
