Design of steel roof and wall cladding systems for pull-out failures

摘要

When thin steel roof and wall cladding systems are subjected to wind uplift/suction forces, localudpull-through or pull-out failures occur prematurely at their screwed connections. During high wind eventsudsuch as stom1s and cyclones, these localized failures then lead to severe damage to buildings and theirudcontents. In recent times, the use of thin steel battens, purlins and girts has increased considerably, whichudhas made the pull-out failures more critical in the design of steel cladding systems. An experimentaludinvestigation was therefore carried out to study the pull-out failure using both static and cyclic tests for audrange of commonly used screw fasteners and steel battens, purlins and girts. This paper presents the detailsudofthis experimental investigation and its results.
