- Abstract
- This report on seismic protection studies of buildings summarizes the various work tasks with respect to accomplishments to date and major efforts underway. Work tasks were assigned to seven groups, the first of which identifies building types. Building categories are being assembled on the basis of data on existing buildings with consideration given to comparative effects of wind and earthquakes. Earthquake intensity is studied through preparation of a model of Boston seismicity. The effect is investigated of local soil profiles and their locations which involve microtremors and basic amplification studies together with suggested building code proposals. Design strategies are identified based on analysis of comparative building codes and costs. The dynamic response of buildings is researched with respect to such factors as ductility and damage. A computer program for non-linear models is being developed. Damage state probability and associated cost matrices are examined. Also, a preliminary analysis of expected future loss computations is undertaken.
