SEISMIC DRIFT CONTROL CRITERIA

The need for seismic drift control is discussed and difficulties in setting criteria are described. It is suggested that the building flexiblity and weight be separated out into a dynamic Flexibility Index. In order to compare buildings of different heights in relation to their dynamic response, which also varies with height, a Seismic Drift Index is suggested. Three tables are presented which show the practical variation limits of the proposed Indexes by reference to a number of representative buildings, and two tables which show the effects of varying the Indexes for buildings of different heights. The buildings indicate the practical index limits and set the stage for standardizing flexibility evaluation and criteria.
