Blast Retrofit Design of CMU Walls Using Polymer Sheets

Abstract

The research presented in this thesis details the development of analytical modeling and experimental evaluation of CMU-polymer walls to blast loading. Polymer sheets were analyzed as a method for retrofit design. This research was done to ascertain the strength, ductility, response to static pressure, investigate connection details, and develop an analytical model of the static resistance function. The analytical model developed for the static resistance was used in a SDOF model to dynamically model the polymer retrofit system. Three types of test were conducted at the coupon, connection, and component levels to verify the analytical model. Once the analytical model was verified, it was incorporated into the SDOF model. Additionally, field tests were conducted on three polymers, and results were compared to the predicted results.
