HEXASAFE: ADDRESSING THE LACK OF EVACUATION CENTER IN DISASTER-STRICKEN COMMUNITIES THROUGH HEXAGONAL SHELTER INNOVATION

Abstract

In the Philippines, where disasters frequently occur without warning, the availability of effective evacuation centers is essential. Traditional evacuation centers, commonly repurposed school buildings, have been found to lack adequate space, privacy, ventilation, and sanitation. This study introduces HexaSafe, an innovative architectural design that addresses these deficiencies and aims to strengthen community resilience and safety during disasters. The study focused on the feasibility and structural strength of HexaSafe in terms of shape, capacity, innovation, wind resistance, seismic resistance, and overall structural integrity. This study focused on architectural design alternatives by developing a conceptual architectural solution as an alternative to conventional evacuation centers. An experimental research design was employed to compare the capability and efficiency of a hexagonal-shaped structure with square-shaped structures using Structural Analysis and Design (STAAD) software. The researchers created the floor plan using AutoCAD software to produce an architectural design incorporating innovative features that comply with building standards. HexaSafe exhibited biomimetic and biomorphic architectural characteristics inspired by honeycomb structures. The design included preparedness for vertical expansion, a parapet roof system to enhance wind resistance, and a courtyard to increase natural lighting within the structure. The results showed that the hexagonal structure experienced lower wind impact (M = 2.07) compared to the square structure (M = 1.43). Additionally, the hexagonal design demonstrated equal load distribution and load resistance. The structure achieved equal stress (M = −0.01) and weight distribution of 80%, compared to the square structure, which recorded stress of M = 0.12 and weight distribution of 20%. The findings indicate that the HexaSafe structure can withstand wind speeds of up to 300 km/h and seismic activity with a magnitude of 8.0, in accordance with the requirements of House Bill 10472 for evacuation facilities. The study highlights the practicality and effectiveness of the HexaSafe design, as its unique shape, capacity, and innovative features provide a robust solution for disaster-prone areas. The HexaSafe design demonstrates strong potential to enhance community safety and resilience during calamities. However, additional tests, such as heating and flooding simulations, may be conducted to further assess the design’s limitations.
