Surface explosions resulting fromterrorist attacks will produce a hemispherical shock wave in the air,which, upon release, can affect\nfive faces of the building which is in front of it. Given the fact that conventional buildings are usually exposed to such explosions,\nthis study examined the effect of pressure to each face of a building on the responses of the structure and has compared different\nrelevant scenarios. This study, which includes the following two steps, was conducted as a case study on earthquake resistant RC\nbuildings, with the help of UFC guideline and using the software SAP2000. In the first step, responses of loading on each face\nwere separately calculated so that they were compared with the responses from overall loading on all faces. The sensitivity of the\nresponses and their ratio to the variables considered were evaluated in the second step. Accordingly, an outline was formed on the\nexplosion hazards considered for these types of buildings.
