Comparison Study of Aboveground Reinforced Concrete Cylindrical Arches Designed to Resist Blast Loads

摘要

The emphasis of this report will be on the methods available to design and analyze aboveground arches for blast loads and also on the final design results and comparisons for each case examined. It is not intended to be an in-depth study on structural dynamics and how it is applied to blast resistant design, but, will include enough background information on the procedures used herein to provide a basis for those procedures. Only the aboveground arch structure will be studied. The blast effects on foundations, openings, end walls, and mechanical and electrical systems will not be considered. The above ground portion of the structure is most affected by the various blast design loads and changes in configuration and, as such, will have the greatest impact on the data used for the final comparisons. Airblast and fragmentation will be the only loads resulting from explosions considered in this report. Keywords: Concrete. (JES)
