Abstract
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In the event of a blast, concrete might not have the toughness needed to absorb the large amounts of energy imparted, even with the moderate steel reinforcement present in many such walls. If the concrete is used as a composite encased with PVC, it is expected that the large mass of the concrete will absorb much of the energy imparted by the blast, while the PVC will provide the needed ductility and tensile strength. In addition, the PVC skins and webs are expected to provide additional concrete confinement, which will improve the response of the concrete section post ultimate. This additional resistance from the PVC is expected to prevent catastrophic failure of concrete walls during an explosion event. In this thesis, two stay-in-place PVC-formed concrete wall systems are evaluated using laboratory static testing. The results of the loading tree tests for both systems are compared to reinforced concrete wall control samples. PVC-concrete samples exhibited additional strain energy when compared to control samples. Experimental evaluation of the confinement contribution to the compressive strength of concrete was also performed in this study.
