摘要

An intense climate-induced disaster such as flood and tropical cyclones has been the occasional season in Indonesia which affecting the vulnerable areas with poor housing construction. Moreover, in the area where there is a combined-risk of climate and natural hazards such as earthquakes, the vulnerability of the population increases with the urgent need for temporary shelter. The study focuses on the preliminary design of a temporary shelter in Lombok, NTB that experiences the tropical cyclone Seroja in 2021 as well as the Mw 6.9 earthquake in 2018. The wind load, as well as the seismic lateral load designs, follow the requirements in ASCE 7–05. The estimation of the hurricane load in the study area is computed from the impact of windborne debris using the missile criteria for hurricane shelters. Seismic analysis is conducted to determine the safety level of the structure under extreme earthquakes. Engineered wood in the form of glulam is designed as the load-bearing element and analyzed to ensure structural safety and stability. A sheathing from plywood is also designed considering the seismicity. Based on the stability and capacity checks on several structural components of the temporary shelter, the study concludes that the preliminary design shows adequacy in safety and stability against extreme cases.
