| Abstract | Most conventional buildings are being constructed to resist gravity, wind and earthquake loads. In many cases blast loads are not being considered when designing structures. However in recent times such considerations will be very beneficial as many blast explosions occur in all parts of the world. Thus being able to know the resistance to blast loads of an already designed or built building would be very useful. This study attempts to obtain the maximum blast load that a steel moment frame could resist when it is designed to resist gravity and wind loads. The structure is assumed to be located in a high wind zone and the design of the frame is done accordingly. Then an analytical procedure is done to obtain the resistance to blast loads. Calculations are done for two types of protection categories and two types of standoff distances. Then the results are compared with two similar studies which include structures designed to resist medium and high seismic loads. The study shows that columns resist a larger charge weight when the distance between the charge and the column is greater. Thus the columns at the bottom are more likely to fail first. Furthermore it shows that the conditions of protection category 2 favour to resist a larger blast load. Comparison between the parallel studies confirm that the blast resisting capacity gradually increases when the design considerations of the structure move from wind loads to medium seismic loads to high seismic loads. |
