THE PERFORMANCE OF LAPPED SPLICES UNDER RAPID LOADING

The impact or dynamic response and resistance of structures or structural components has been of increasing interest in recent years. The failures of lapped splices at the bases of some concrete highway support structures during the San Fernando earthquake led to questions as to the suitability and adequacy of a lapped splice subjected to fast loading rates. In addition, the damage produced by hurricanes and tornadoes surpasses earthquake damage and gives added impetus to the study of structural behavior under dynamic loads. In this investigation the behavior of lapped splices subjected to impact loading was studied. The objective was to compare the strength and behavior of splices under static and dynamic loads and to determine whether the design provisions based primarily on static tests could be relied on under dynamic loading conditions.
