The purpose of this study is to determine the capability of mechanical splices in reinforced concrete to develop the ultimate strength of typical reinforcement without limiting its ductility, as required by UFC 3-340-02. This study also follows the UFC 3-340-02 requirement for a specific mechanical coupler to be tested in a dynamic application prior to use in blast resistant structures. Mechanical couplers have been developed to meet requirements in conventional ...
This paper describes a technique used to characterize the loading and damage generated by the primary fragments from cased munitions on reinforced concrete slabs or walls. It has been observed that the damage generated by the fragments, while usually of secondary importance to the airblast, can in some circumstances dominate the response. Test observations indicate that fragments from cased conventional bombs, not only directly load a wall element through momentum ...
