Abstract: In support of plans to add a second control room to the Rocket Engine Test Facility at NASA Lewis Research Center, Celveland, 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. The analysis and design calculations were based on procedures from Army Technical Manual TM 5-1300/NAVFAC P-397/AFM 88-22, "Structures to Resist the Effects of Accidental Explosions," and the computer program CBARCS, which automates some of the procedures in the manual. To evaluate the degree of conservatism in the analysis, experimental data with charge weights and structural dimensions similar to the control room's were selected and analyzed. Results indicate that the existing room will safely withstand an explosion equivalent to 1,000 lb of TNT detonated at the rocket test stand 20 ft away. To survive the same accident the new control room (to be constructed on top of the old one) should have 1-ft thick walls (existing walls are 2 ft thick) with 0.33 percent reinforcement (existing walls 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. This analysis results in a much more economical design for the new control room than would have been achieved by constructing a new room identical to the old control room. Also, comparing results of this analysis procedure with data provided a good estimate of safe operating criteria and the maximum capacity for the control rooms.
