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></align> | |

| <align justify><fs medium>Aesthetics may play a large role in the acceptance and desirability of these fabric-formed panels but one of the key issues we will wish to address is that of efficiency. To that end the theoretical capacity of a normally reinforced concrete panel formed in a rigid formwork will be compared to the theoretical capacity of the fabric-formed panel using the FEA program //ADINA//. Experimental capacities from our test results will also be compared with the theoretical results.</fs></align> | |
