The future holds many challenges for structural steel research .The ongoing work necessitated by the two recent earthquakes that most affected conventional design methods , namely, the Northridge earthquake in the US and the Kobe earthquake in Japan ,will continue well into the first decade of the next Century. It is very likely that future disasters: We can no longer be content with saving lives only ,but we must also design structures which will not be so damaged as to require extensive repairs .
Another major challenge will be the emergence of many new materials such as high-performance concrete and plastic composite structures . Steel structures will continually have to face the problem of having to demonstrate viability in the marketplace .This can only be accomplished by more innovative research .Furthermore , the new comprehensive limit-states design codes which are being implemented worldwide ,need research to back up the assumptions used in the theories .
