The Role of Geometry on Livestock Facilities under Different Types of Actions

The objective of the paper is the investigation of the livestock facility response, in the specific conditions of seismicity of Romania. All buildings are designed for a particular use, and this is reflected in their shape, size and layout. The design and development of a traditional livestock facility can provide important information about agricultural or industrial practices in the past. Small details and the patina of age contribute to the creation of a building's unique character. There are situations in which the geometric conformation of the buildings as a result of modernization and structural interventions has been changed, but it is known that all buildings have to respect the provisions of design codes. This is the reason for that the role of geometry and materials in the response of buildings under different type of actions as seismic and temperature actions were analysed. The only difference between two types of actions consists in time: the earthquakes are acting quickly; they need just a few seconds for damaging the structures while the temperature is acting slowly, and the dramatic time is measured in hours. The validation of these results was made with the aid of modal analysis software. The obtained results characterize the building's behaviour in the small amplitude vibration range
