Proposal of Resilient Housing Features for the Disaster Affected Community of Bangladesh

Abstract

Thinking resiliency in terms of housing features for post disaster housing reconstruction (PDHR) is a paramount initiative after a disaster. Therefore, the aim of this research is to ascertain the demands of the disaster victims and propose a wind-resistant, resilient housing prototype that would be affordable. Based on a three-month survey of the region severely damaged by Cyclone SIDR in Bangladesh, this research argues that PDHR’s planning features are significantly short of the victims’ choice, need, and demand, forcing them to quickly modify or transform the reconstructed houses. Based on the survey, a prototype covering an area of 37.21 sq. m (400 sq. ft) with a hybrid construction technique and a cost model are proposed that will be a resilient solution against cyclones and other natural hazards. Additionally, the proposed house was modeled using finite elements, and its findings are within the International Building Code’s allowable limits. In conclusion, this paper proposes some guidelines to strengthen Bangladesh National Building Code (BNBC) that would enable to build a resilient housing society in the disaster-prone areas.
