Earthquake Resistant Assessment of Building Construction Technique in the Nayagaun Settlement of Kavre before Gorkha Earthquake

Abstract

The major earthquake on April 25, 2015 (7.8 Mw) and the
aftershock on May 12, 2015 (7.3 Mw) caused severe damages on
the Nayagaun settlement of Dhulikhel Municipality, Kavre. This
study proposes to highlight the extent of damages in the buildings
due to the absence of the earthquake resistant components. In
this study, the suitability of the building construction techniques in
the study area has been addressed after knowing the
consequences faced due to the absence of the earthquake
resistant components in the buildings. This study provides idea on
the earthquake resistant components and its significance in the
residential buildings during the earthquake period. In this study,
the types of the buildings damaged are tabulated according to the
typology of the buildings whereas the type of damages incurred
are categorized based on the grade of damages (partially
damaged or fully collapsed). Some mitigating measures are
identified throughout the study to overcome the future
earthquakes
