A Proposed Design of Disaster-Resilient Housing by Adopting Botong Bamboo (<i>Dendrocalamus latiflorus</i>) in Davao Oriental

The occurrence of the super typhoon Pablo, along with frequent earthquakes, and flash floods, served as a pivotal phenomenon towards the call for enhancing disaster response and mitigation strategies in Davao Oriental. This study aimed to design disaster-resilient housing in Davao Oriental using Botong bamboo ( Dendrocalamus latiflorus )- a locally accessible material that diminishes construction costs without compromising its physical and mechanical attributes. To do so, the soil properties-with a bearing capacity of 677 kPa-was obtained using the Meyerhof’s bearing capacity theory with the mechanical properties of bamboo provided from related literature and the design loads (i.e. dead, live, seismic, wind) were approximated and applied onto the structure model. By simulating the proposed design model into the Finite Element Analysis (FEA) via STAAD in adherence to NSCP 2015 and AISC-LRFD specifications, force reactions were generated in the structural members; 87.46 kN for the columns, 26.23 kN for the roof truss, 9.22 kN for the slab truss, 2.87 kN for the purlins, and 32.68 kN for the bracings. Architectural and structural plans were provided applying the validated findings. It was proven that Botong bamboo is indeed a promising material for constructing disaster-resilient housing. This study is an attempt to attain the following Sustainable Development Goals (SDGs): SDG9: the need for resilient structure and innovation, and SDG 11: making human settlements inclusive, safe, resilient, and sustainable.
