- Abstract
- Recommendations concerning earthquake engineering research provided by a committee on the Alaska Earthquake are discussed, including: (1) improved earthquake resistant designs and better methods of structural analysis should be developed; (2) more data on strong-motion ground movements should be collected; and (3) more knowledge on tidal waves and improvement in the tidal wave warning system is needed. It is pointed out that before structural damage can be assessed, it must be defined. The Modified Mercalli Intensity Scale is discussed as an example of a descriptive classification system for structural damage. Although existing structures can be studied both experimentally and analytically whenever there are signs of distress, the study procedures are known to only a small number of engineers. Therefore, it is suggested that fuzzy sets be utilized in damage assessment. Preliminary formulations of elementary fuzzy set relations to the problem of damage assessment of existing structures are provided.
