The research theme, it was a part of a large subject of study, which attracts the knowledge from different fields (mechanics, construction, computer science, technical graphics, computer aided design). The force of hurricanes is illustrated by an ascendant scale with five values. The weakest hurricanes are of one category and do not produce material damage. The speed of wind into a hurricane of one category it is between 115 and 157 km/h, with a speed of 250 km/h ore more into a hurricane of five categories. The houses begun to be destroyed by the wind force which reaches speeds between 178 and 210 km/h. The most violent five hurricanes of Atlantic Ocean were: Gilbert (1988, wind speed of 299 km/h), Mitch (1998, 287 km/h), Hugo (1989, 260 km/h), Andrew (1992, 250 km/h), Camille (1969, 320 km/h). During severe thunderstorms or hurricanes, homes may be damaged or destroyed by high winds. Debris flying through the air can break windows and doors, allowing high winds inside the home. In extreme wind storms, the force of the wind alone can cause weak places in houses to fail. Items susceptible to wind around the house include air conditioners, storage sheds, fences, trees, and backyard items like lawn furniture, portable spas, and trampolines. Items susceptible to wind on the house include awnings, gutters, shutters, patio covers, television antennas, chimneys, siding and windows. Certain building configurations are more likely to sustain wind damage. In general, the higher the building, the more it is exposed to the wind and greater its potential for damage.
The experimental model for the simulation was built in CAD program after the dimension of a real house. The model is presented in Fig.1 and Fig.2
In simulation we put the following initial condition:
- wind speed of 210 km/h;
- air temperature of 200C;
- ambient pressure;
