Results are presented for that part of the Optimum Seismic Protection Study which examines several prototype buildings for the purpose of obtaining initial building costs data and input data for dynamic analysis. An apartment building, 60 by 200 feet, was selected since the study emphasizes housing, and a large portion of urban construction consists of multi-unit dwellings. Each building is designed for five levels of seismic resistance. The city of Boston wind load of 20 lb/sq ft for structures greater than 800 feet distant from low mean water is used. Results are reported for six basic groups of concrete buildings selected for height, frame, and wall construction and another group of eleven story concrete buildings in which shear walls are replaced with moment frames. The design procedure for both concrete and steel buildings and strengths are described. A summary of the data for dynamic analysis and how it is computed is provided and results of cost comparisons given. A series of architectural drawings showing building types and charts depicting cost analyses, indices to computations, and structural design is included.
