Seismic Design:Cost Impact on High-Rise Residential Structures.

摘要

This research study examines the cost impact of providing increased seismic resistance for prototype high-rise apartment buildings. Eleven U.S. cities were chosen as case studies. Structures were designed to meet the Local Building Codes and seismic requirements therein,if any,and were redesigned to meet the seismic criteria of the HUD Minimum Property Standards for Multifamily Housing, 4910.1,and the Uniform Building Code 1973. Also the Uniform Building Code 1976was used to examine the cost impact of this code in two of the case study cities. The cost impact generally proved to be greatest for cities which use their own local code requirements rather than that of one of the National Model Codes. For cities whose local seismic requirements are not stringent,upgrading resulted in significant additional cost ranging up to $3.42per square foot.
