Abstract:

The Iraqi Village Project is a planned training center that will create a realistic training environment to simulate urban warfare in the Middle East. However, the materials, design, and construction methods typical in the Middle East do not provide adequate seismic protection. The Los Angeles District tasked the U.S. Army Engineer Research and Development Center, Construction Engineering Research Laboratory ERDC-CERL with developing alternative construction methods consistent with the overall project objectives and to test structural components to determine whether the alternative construction methods are adequate to withstand seismic design loads. ERDC-CERL conducted in-plane cyclic load tests on three double wythe panels and out-of-plane cyclic load tests on 24 double wythe wall strips of the same materials and construction to be used in the project. Unimproved walls and two alternative methods of strengthening were also tested. Elements to be addressed were the lack of adequate in-plane shear strength to resist lateral loads, and the lack of minimum reinforcement within the walls. Two surface applied overlay systems were considered as candidates for mitigating seismic risk. Results of the testing were analyzed and documented, and recommendations were made, including design detailing.
