DISPLACEMENT BASED SEISMIC ASSESSMENT AND DESIGN FOR BUILDINGS IN LOW-TO-MODERATE SEISMICITY REGIONS
Authorities around the world now recognize that buildings and infrastructure in low and moderate seismic regions require a minimum level of protection against future earthquakes, thought infrequent and random they may seem. What is required is not only the introduction of a seismic design standard based on performance, but also investigation into the existing building stock to decide if retrofitting is required. In this study, preliminary step-by-step procedures have been developed for the purposes of seismic assessment and design, for low to medium-rise buildings and high-rise buildings in the low to moderate seismicity region. Calibrations of various dynamic amplification factors and shift factors have been investigated. The empirical formulae for predicting those factors are developed for seismic assessment by using dynamic analyses. However, a number of important issues (e.g. Drift demand-performance level, drift-damping relationships) are still a matter for further research.
