Abstract

Nepal is an earthquake prone country and it has experienced several devastating earthquakes in the past. Since a huge number of buildings in the country have been made without involvement of engineers, these buildings are not earthquake resistant buildings. From the above statement it is clear that building damage would be the most serious part of disaster. Quick inspection of damaged buildings is the first emergency work after the destructive earthquake. It is quite necessary to protect the secondary disaster caused by damaged buildings through inspection of buildings whether they are safe or not for aftershocks.

The recent earthquake of 25th April, 2015 caused huge devastation in Nepal. Quick inspection of damaged houses after the earthquake has been conducted by different organizations in Nepal. However, there is no uniformity in using inspection sheets. Six out of ten organizations have used the sheet of DUDBC, from which data of quick inspection have been collected. Since the damage patterns of RC and masonry buildings are different, it is necessary to develop different sheets depending on the feature particular to each structure as well as to give uniformity to the sheet adaptable to any organization. To achieve this, the sheets of DUDBC, Nepal, NILIM, Japan and BRI, Japan were compared. From the comparison, it was found that the DUDBC sheet has many weaknesses compared to those of NILIM and BRI for RC buildings. The inspection data provided by different organizations were collected and analyzed. Five buildings were inspected in detail by using DUDBC and NILIM sheets. The findings of the five buildings were compared and analyzed. Including all the above mentioned items a new inspection sheet has been developed and proposed for the use of inspection of RC buildings in Nepal. In the new sheet the structural and non-structural parts of damaged buildings are separated and can be judged quantitatively. This sheet will play an important role for inspection during the emergency period of post-earthquake to obtain good results in short time.
