Abstract Temporary houses are an urgent demand for post-disaster condition. These construction systems involve creating modules off-site and assembling them on-site, offering advantages such as reduced construction time and lower costs. Key materials often include Glass Fiber Reinforced Polymer (GFRP) and timber, ensuring durability, resilience, and easy assembly. The sustainability and adaptability of these units further enhance their suitability for temporary housing in crisis situations. Consequently, these systems form a burgeoning field of study with the potential to significantly improve disaster management strategies. A comprehensive review of the properties and manufacturing methods of different composite materials are given, as well as highlighting successful models of temporary housing solutions. This research works develops innovative designs for three prototypes of temporary houses made of a modular panel made of (GFRP) supported by a lightweight timber frame. The houses were designed to fulfil the needs of displaced people and to be easily assembled, disassembled and stored for future need. Each unit contains multi-purpose rooms, a toilet, and a kitchenette, with different models designed for different family sizes. All the suggested models are demonstrated in 3D illustrations showing interconnections and provisions for needed water supplies and sewage systems. The study involved the manufacturing of a practical model and experimentally testing its components and manufacturability. The cost of producing a single panel was calculated, as well as its feasibility for assembly by non-skilled workers using basic tools. Additional investigations were conducted to examine the time required for both assembly and disassembly by various groups. Laboratory experiments were carried out on composite timber GFRP panels produced through the hand-layup process. These experiments underwent three distinct stages. Firstly, axial tensile tests were performed on GFRP skins to evaluate their material properties, while bending tests examined the main sections of these panels. Secondly, testing a group of panels under gravity loads was conducted from both sides to assess their structural performance, the failure mode, and the bond between the timber frame and the GFRP skin. Finally, half-scale models were subjected to lateral loads equivalent to wind speeds of 45 m/s to further analyze their performance characteristics. To address the proposed models more as a practical solution for post disaster housing, an economic study was conducted. This study involved various aspects such as identifying suitable locations for temporary housing complexes and suggesting architectural models that fits to different family sizes and requirements. Additionally, the study encompassed equipping these sites and units with essential needs such as electricity and water to ensure residents daily needs are met effectively. The proposed model, which was fabricated using locally available lightweight materials, demonstrated exceptional structural efficiency and resilience against wind loads and lateral forces. The success of the existing structure was more than (64%) wind-resistance while achieving a considerable reduction in economic costs (26%) and installation time (50%) faster than current alternatives used in post-disaster scenarios. |
