| <fs medium>For this phase of the project full-scale concrete wall panels will be designed, constructed and tested for lateral load carrying capacity. The results of control panels constructed using plain concrete will be compared with those reinforced with steel or fiberglass reinforced polymer (FRP) reinforcing bars. Results from the experimental testing will be compared with those obtained from an analytical analysis using the finite element analysis program //ADINA//.</fs> | <fs medium>For this phase of the project full-scale concrete wall panels will be designed, constructed and tested for lateral load carrying capacity.

| <fs medium>For Phase III testing of full-scale concrete wall panels may be difficult given the capacities of the vacuum chamber equipment we are able to configure. While it would be preferred to test a full-scale panel similar to one that would be used in a practical application it is believed that acceptable results and conclusions will be obtained from scaled down panels as well.</fs> | <fs medium>For Phase III testing of full-scale concrete wall panels may be difficult given the capacities of the vacuum chamber equipment we are able to configure.
