Performance Based Design of Multistoried Building with Transfer Slab

In the last few decades, there has been a growing trend to utilize reliability-based methods of seismic evaluation for assessing the vulnerability of structures subject to ground motion vibrations. The traditional deterministic approach for seismic assessment of structures was found to be inadequate owing to the uncertainties and randomness commonly encountered under the effect of an earthquake. With the advent of digital technology, accuracy of seismic analysis increased which paved way for probabilistic approaches which offer a more realistic and rational approach. Fragility analysis is one such approach which correlates demand and capacity to establish the probabilistic characterization of the demands with respect to certain limit states. Developing mega cities leads to increase population in the city and there are not sufficient spaces provided by large number of buildings to accommodate the increasing population. High-rise buildings address this challenge as one of the solutions for the developing countries and mega cities. In addition, high-rise buildings give aesthetic to cities and they are signs of modern development. Comparatively, lower high-rise buildings (approximately 8~20 stories) are more common than super high-rise buildings (usually more than 30 stories) over the worlds. Although it is imperative to know structural behavior of both buildings including their seismic performances. High-rise buildings exhibit far more complex dynamic properties that require careful study and a complete understanding before they can be confidently resided in.
