Design of buried arches to resist blast loads
Equations were developed for determining reactions resulting from dead loads, i.e. earth cover, concrete, and temperature changes, at any section for two-hinged buried, semicircular arch of uniform cross section; equivalent surcharge loading method for designing against blast loads is presented; threshold method and upper bound method, are presented for case where structure is located above and below groundwater table respectively; calculations to determine overpressures that should cause failure to various sizes of arch structures were made and summarized in form of convenient graphs.
