“…The determined values of the stress drop are listed in Table 3, they are in the range from 1.17 to 778.3 bar. Pandey et al, 2001 have been reported such high values of the stress drop for Chamoli earthquake, India.…”

“…Brune (1970) has given a model to calculate the source parameters using near and far field displacement amplitude spectrum as a function of the physical parameters at the source. Abercombie and Leary (1993), Zoben and Hasakov (1995) and several others are notable recent contributors in the field of source parameters studies (Pandey et al, 2001).…”

“…The study was conducted in seismic zone III, and it was discovered that while ribbed slab structures have fewer columns than typical slab buildings, they perform less well in high seismic zones. However, this performance can be enhanced with structural retrofitting [8]. Pavan Kumar Jogi, Durga Chaitanya Kumar Jagarapu, and CH.…”

In the analysis and design of structures, seismic ground motion is a significant factor. Seismic criteria consideration is necessary for serviceability and feasibility of existing as well as new structures. Time History analysis is the one in which base is subjected to a specific ground motion and dynamic response of structure is analysed at each increment of time. The bracing system increases the structure’s resistance to lateral loads by transferring load from the frame to the braces. This study uses the ETABS software to do a time history analysis on a G+4 RCC building with a waffle slab and an X-type bracing system. For designing purposes, the IS 456-2000 code is thought about. According to IS 875-part 1, live loads are measured, and IS 1893-2016 earthquake analysis is carried out. For this structure, a number of factors are analysed, including storey drift, base shear, storey stiffness, and storey displacement, among others.

“…Uttarakhand state falls in Zone IV (High Risk) and Zone V (Very High Risk) of the Bureau of Indian Standards' earthquake zonation map (Indian Standard, 2002), thus making it vulnerable to seismic hazards. The extensive damage to human life and property in Uttarakhand caused by the Uttarkashi and Chamoli earthquakes, underlined the ramifications of failing to incorporate seismic vulnerability in Master Plan formulation (Pandey et al 2001). Additionally, it is more challenging to reduce seismic vulnerability, in existing urban areas where already concentration of built-up and people has taken place.…”

Himalayan foothill city of Dehradun in Uttarakhand state is located in a tectonically active region and is prone to earthquakes. The growth of Dehradun city is analysed using high resolution remote sensing datasets in the current study, with a focus on its vulnerability to seismic risks for single and double storey structures as the city is predominantly made up of low-rise structures. Analysis shows that 10% of urban expansion has occurred in spectral acceleration zones that are vulnerable to double-storey buildings, while 38% of urban expansion has happened in spectral acceleration zones that are vulnerable to single-storey buildings. The proposed land use as per Dehradun Masterplan 2041 is examined with reference to National Earthquake Hazards Reduction Program (NEHRP) for seismic regulating provisions. It is emphasized that the intended land use is incongruous in areas with higher spectral acceleration zones since it comprises structures with higher occupancy and the amenities required during post-earthquake rehabilitation. On the other hand, the open spaces are more appropriate in these locations, which will lessen susceptibility as the influence of seismic forces can be sufficiently attenuated. The present study, thus highlights the significance of including seismic risk information in urban planning processes in order to ensure resilient cities.
