a recent engineering graduate designs a small steel structure for a client using educational structural design software leftover from college. he later learns that the software gives accurate stress analysis for tension, but does not properly predict buckling of columns in compression. he purchases the professional version and a revised analysis shows that the building is not as safe as first believed. a large snowfall would create a static load that could cause the supporting columns to buckle and the building to collapse. the probability of this snowfall occurring is once every 10 years. what should the engineer do?
