ASSESSMENT AND STRENGTHENING OF HERITAGE BUILDING

Abstract

Indigenous earthquake-resistant traditional housing technologies have developed in different parts of the world to facilitate the people to safely withstand earthquakes. Unfortunately, these traditional construction techniques are becoming unpopular due to lack of knowledge about their structural actions and lack of research in these areas. These traditional techniques like Dhajji-dewari houses performed extremely well in past earthquakes. There is only qualitative information is available regarding performance of Dhajji wall in earthquake. Till date no guidelines is available in forms of code and also no engineering tool is available to provide help in analysis and designing of Dhajji-Dewari house construction. In this paper behaviour of Dhajji wall is investigated and then model is proposed based on the findings of experimental program conducted on Dhajji wall at the Earthquake Engineering Center of Peshawar, and then a suitable retrofitting technique is suggested based on findings.
