Abstract: Nepal suffered a massive loss of life and property from Gorkha Earthquake in 2015AD. Many building structures were either partially or fully damaged and most affected were classic buildings and monuments which were constructed without any design consideration and didn’t pose any resistance during the earthquake. After, a broad study and hazard analysis of earthquakes, the Nepal government concluded that the construction methods needed to be revised. The first building regulation in 1994AD known as NBC: 105: 1994 was drafted after the earthquake in 1988 in the eastern part of Nepal. Moreover IS 1893 (Part 1) and IS 13920 codes are still used widely for earthquake resistance design and detailing. But now the Department of Urban Development and Building Construction (DUDBC) has introduced an updated building code of practice NBC 105: 2020 for earthquake-resistant design. In this paper, an effort is done to analyse and compare the effects on buildings of 2-Storey and 3-Storey under the application of IS and NBC code. Equivalent static analysis was carried out with the help of ETABS v19.1.0 and the parameters like base shear, storey displacement and storey drift under both codes are compared. The analysis result shows that the response of building subjected to NBC: 105: 2020 exhibits higher storey responses compared to IS 1893: 2016. Also, the NBC code demands a higher percentage of reinforcement requirements compared to IS code.
Keywords: Storey Displacement, Storey Drift, Base Shear, Reinforcement Requirement.
