Also, the discussion is limited to normal buildings without any special devices, like base isolation and other energy absorbing or dissipating devices. But, with no loss of generality, the broad concepts discussed in this document are valid for both RC and Steel buildings. Since most buildings built in India are made of RC, the dominant set of examples used is of RC buildings. It is an attempt to respond to some of the frequently asked questions by Architects and Structural Engineers regarding behaviour of Reinforced Concrete (RC) and Steel buildings under the action of lateral loads, especially during earthquakes. The book dwells on basic concepts in earthquake resistant design of buildings, first describes these at a conceptual level and then articulates further with numerical examples. This book explains concepts in behaviour of buildings during earthquakes. The importance of non-structural elements is also specified and design guidelines based on the sensitivity of the elements are provided. Criteria for selection of foundations are specified. Modelling of the tall building and changes in the design considerations are listed. In analysis for seismic loads few changes in comparison to IS 1893 part 1: 2016 are also reported. In the design of tall building other parameters that need attention are wind load analysis using wind tunnel test, P-Δ effect, secondary effect like creep & shrinkage, and temperature. The selection of structural system and plan dimension are specified based on structural configuration and seismic zone. In present paper various aspects and issues related to tall buildings with reference to IS 16700 have been reviewed. Recently, BIS released the Code IS 16700: 2017 "Criteria for Structural Safety of Tall Concrete Buildings" under CED-38 committee. National building code and other Indian standard codes are not sufficient to adequately address various issues related to tall building. In comparison to low and mid-rise buildings the design criteria for tall buildings are different. Tall buildings are emerging constructions in Indian cities due to urbanization.
