A New Static Nonlinear Procedure for Assessment of Seismic Performance of High-Rise Buildings

Abstract:

Article Preview

A new static nonlinear pushover procedure is proposed for assessment of seismic capacity for high-rise buildings. Rather than simply combining the results carried out by modal inertia force distributions to estimate the total building capacity after pushover analysis, the present study develops in advance the most critical lateral load distribution which is developed via energy dissipation analysis based on least-energy principle. The advantage of the present method is that the effect of different earthquake input directions can be well considered, as well as that unstable solutions due to employing linear method to combine the nonlinear analysis results can be avoided. Thus, the performance of building can be evaluated more reasonably. By comparing with the results from nonlinear response history analysis using real earthquake tremor monitoring results, the validity of the present method is validated.
