Abstract: This paper presents a preliminary study to assess the structural integrity of low-rise buildings which are designed according to appropriate provisions of ANSI A58.1-1982 and ACI Code 318-83. The main purpose of this study is to demonstrate how the knowledge of different scientific and engineering disciplines can be combined and synthesized to assess the actual degree of protection against natural hazards. The low-rise buildings considered in this paper are a shear wall structure and a flat-plate structure supposedly located in New York City. These structures are designed to resist earthquake and wind forces separately. For the reliability assessment, seismic and wind hazards in New York City area are eliminated. The structural response to these hazards is then evaluated by using the formulas specified in ATC 3-06. The variability of the structural response is quantified. In addition, the variability of the structural capacity is also assessed. The structural integrity is measured in terms of the annual limit state probability which provides a quantitative measure for comparing the relative extent of risk due to different natural hazards such as wind and earthquake.
