Abstract
This paper presents two approaches of estimating the control force magnitude in the building structure's seismic design. One is by spectrum average in frequency domain, and the other is by nondeterministic Monte Carlo analysis in time domain. the spectrum method is proposed to find the estimation by averaging the system's frequency response with an earthquake spectrum as a weighting factor. the nondeterministic method is based on sets of potential ground motions generated numerically. the approaches are developed in the concept of performance design, with studies based on the site potential seismic hazard and presenting results at different levels of displacement objective. the output of force estimation is arranged in tables or curves in terms of control ratio objective and the structural weight. the approaches are presented as a general concept and applicable to various controller types. © 2010 American Society of Civil Engineers.
