Abstract

According to the strategic geographic position of IRAN with the probability of terrorist threats and air strikes, and also the important crucial role of the tanks, their construction by taking passive defense measures and considerations is necessary. Because of few researches on the vulnerability of tanks against the loads due to explosion, investigate the importance of this type of structures against blast loads is increasing. In present study a hypaethral cylindrical concrete tank, exposed to air blasting by one cubic explosive TNT with weight of 352.08 kg has been modeled. The tank is modeled in four situations such as: empty state, 1/4, 1/2 and 3/4 of body height full of liquid. The results of simulation showed that damages of compressive and tensile in the empty tank are more critical than other modes, and the manner of hypaethral concrete tanks against explosive loads is different from their manner against seismic loads caused by the earthquake. It was also shown that the conwep method has considerate only the effects of the explosion and at least 25% reduction achieved in compressive damage compared with the results of the AUTODYN. The results of this study can be used in retrofitting and safe design of fluids storage tanks to resistance against the blast loads.
