Seismic assessment of existing structures by displacement principles

Abstract

This paper presents a practical method for estimation of the roof and maximum inter-storey drift ratios which can be utilized in the approximate seismic assessment of existing building structures. The height-dependent building models employed can represent the existing buildings of different height which are laterally supported by walls, moment resisting frames or a combination of walls and frames. In the employed macro model, realistic estimations of the distribution of floor lumped masses and height-wise lateral stiffness of existing buildings were considered. Extensive dynamic analyses were conducted to investigate the generic modal displacement hypothesis and to model drift parameters of..
