“…NTHA is one of the most powerful techniques for achieving the performance of the RC buildings under design seismic intensity. Therefore, selection of appropriate ground motions becomes most important, since the random nature of ground motions may cause uncertainties in the response of structure [40,41]. According to ASCE 7-16 (2016) [4] and FEMA P695 (2009) [42], both natural and synthetic ground motions can be used for evaluation of building performances.…”

Design of reinforced concrete (RC) buildings with a direct-displacement-based design (DDBD) method has been used extensively for the last few decades around the world. As compared to force-based design (FBD) method, DDBD provides advantages in cost-reduction, construction timing, and better structural performance. This paper investigates the DDBD methodology for G + 3 storied RC buildings, having different structural configurations by varying bays in the longitudinal and transverse directions, but having the same total plan area. The selected case-study RC buildings are analysed via non-linear time history analysis considering seismicity of zone-V of Indian regions. A suite of different spectrum compatible ground motions is used. The seismic behaviour has been analysed in terms of base-shear ratio, ductility demand, displacement profiles and drift ratios. The results illustrate that the DDBD procedure proves to be useful in designing RC buildings situated in seismic regions of India and are competent enough to withstand lateral forces due to seismic excitations.

“…In this context, a *Corresponding Author Email: pritamhait15@gmail.com (P. Hait) comprehensive review [10,11] has been published by the authors on local and global damage index (LDI and GDI) of both bridges and building along with their mathematical expressions. In the overview seismic zonal (IS: 1893-2016) based damage assessment [12] had been explained for RC buildings with different structural configurations for reliable damage assessment of structures to make the study robust.…”

Structural damage can be controlled in performance based seismic design (PBSD) according to the requirement under a certain hazard level. During strong ground motion (GM) such buildings suffer minor to major damages depending on the shaking level of GM. The available damage assessment methods are complex, tedious and time-consuming procedure. In the present study, a simplified empirical model has been proposed that computes the GDI in a single step using the engineering demand parameters (EDPs) namely joint rotation, Inter storey drift (IDR), peak roof displacement. It has been found that the proposed method gives results of GDI near to Park-Ang model. It has been observed that the ground storey suffers maximum damage for all cases. Further, a relationship has been established between ground story DI and global DI. The proposed model effectively estimates reliable DI and could be used as a powerful tool for estimating seismic damage in buildings, especially for massive structures.
