Response of Prestressed Concrete Roof Elements of a Buried Shelter Subjected to a Surface Explosion
Dynamic nonlinear analyses were conducted on pretensioned and conventionally reinforced precast concrete members that were embedded in soil and loaded by a surface detonation of a high explosive. The single span members were analyzed as one foot wide solid sections in plane strain. The ends of the members were cantilevered past the supports to take advantage of additional restraint provided by the soil. The soil was modeled as a uniform pressure applied to the top surface of the members with elastic, perfectly plastic springs distributed over the cantilevered portion of the members. The dynamic forcing function from the explosion was modeled using commonly accepted formulas and was applied as a pressure to the top surface of each member. Soil-structure interaction effects were approximated in the analyses. The dynamic analyses were conducted on a PC using a computer code, BLASTSDF.
