In support of plans to add a second control room to the Rocket Engine Test Facility at NASA Lewis Research Center, Cleveland, OH the existing control room was analyzed to determine the most severe accidental explosion it could safely withstand. This potential accident was used as the design threat to develop a preliminary design for the new control room. To evaluate the degree of conservatism in the analysis, experimental data with charge weights and structural dimensions similar to the control rooms were selected and analyzed. Results indicate that the existing room will safely withstand an explosion equivalent to 1,000 1b of TNT denoted at the rocket test stand 20 ft away. To survive the same accident, the new control room to be constructed on top on the old one should hav e 1-ft-thick walls existing walls are 2 ft thick with 0.33-percent reinforcement existing wall have 1.55 percent. Comparison of data with analysis indicates that an accidental explosion equivalent to approximately 1,800 lb of TNT will cause unacceptable damage to the control room.
