ABSTRACT

Commonly, blast and impact loads are of subsecond duration and magnitude tens of times larger than any other loads in the design life of the structure. The maximum positive or rebound negative peaks of stress or displacement are critical for the structure's survival and subsequent vibrations will only be important if the loads are repetitive. For some industrial structures blast and impact forces are repeated in-service loads and the response must be checked as a serviceability limit state including cracking, vibration and fatigue.
