Abstract: 

Each year, many people lose their houses due to natural disasters. In Iran, in recent years, numerous people have become homeless because of devastations inflicted by earthquakes and floods. Following such catastrophes, providing makeshift shelters for the survivors is the first and most important task. Tents are a common solution to the sheltering problem. However, despite the fact that a variety of tents have been designed and produced, most of them fail to meet the durability requirements of the climate of Iran and the specific cultural needs of the region. The investigations showed that at present there are just limited models of tents in Iran available for sheltering the survivors in disastrous situations. A number of problems have been highlighted regarding these tents. For instance, the interior space of tents is not suitable for movement of residents and there is no privacy for people in the tent. Besides, as the tents are designed as a big room, all of the clean and filthy equipment are stored in one place. Also, these tents are not appropriate for diverse climate of Iran, because the windows and vents are not adequate to make enough ventilation and air exchange for tropical regions. Moreover, they are not appropriate for chilly and rainy regions to prevent draught and water inside the tent. As the tent floor is at the same level of the surrounding ground, water and mud may enter the tent. Furthermore, setting up the tent requires a lengthy and cumbersome procedure. Finally, the poles, pegs and ropes are not strong enough against the pressure of gales and they themselves may pose threat to the safety of their dwellers. Therefore, a concept design for a tent was presented that addresses the discussed issues. The proposed concept has a spring structure, which holds it in place and there is no need to any rope to create tensional forces. Furthermore, the new concept has a repeating structure and consists of similar modules. Therefore, using similar parts with the same size and shape helps user to assemble the tent easily in a short time. The spring structure makes the tent residence against powerful winds. In order to make the tent resident to the dampness, the suitable impermeable material was searched and suggested. The tent floor is designed in a way which slightly higher than the ground and prevents the influx of water and mud into the tent. By increasing the size and number of the windows, ventilation and lightness is improved. The interior space was divided into several parts. Therefore, the clean and unclean, necessary and unnecessary equipment can be stored separately. For instance, dirty shoes can stay out of the dining and sleeping spaces. The form and location of the entrance door is in a way that inside the tent is protected from the sight of passer-by strangers, an extremely important point in Iranian culture. The concept is simple and the raw materials for construction of this tent are available in the country. Therefore, it is possible to produce it locally. The next step in the development of this product will be making a prototype and evaluating it in the field. The mass production of this concept can effectively save the future survivors of natural disasters.
