TRACKING BEHAVIOR IN TIME OF BUILDINGS AND LANDS
" Current Tracking of constructions apply to all buildings of any category or class of importance and ownership form on Romania territory, except for residential buildings with ground floor and ground floor plus first floor household annexes located in rural areas and in villages belonging to cities”, as well as temporary constructions, and has a permanent character, its validity length coincides with the physical length of existence of these constructions "- Normative document regarding the behavior in time of buildings indicative P130-1999
Within monitoring projects, tracking behavior in time of construction is carried throughout their entire existence, starting from the moment of execution and is a task of collecting, interpreting the resulted information from observations and measurements conducted to determine position changes occurred over time, in order to be ensured stability and reliability in exploitation.
The results provided in a project of tracking behavior in time of constructions is considered a vitally important information needed to determine whether they can be operated safely.
From the point of view of used methods through which is performed tracking behavior in time of construction and land we can distinguish:
- Physical methods: devices with which measurements are made are located on the studied building, or inside it, situation in which devices move with the construction. Throughout physical methods generally are measured relative displacements.
- Geometric methods (geodetic): in this case are reported position of certain fixed points on the construction, to a series of fixed points located outside the area of influence of factors acting on buildings and land on which they are placed. These methods determine vertical, horizontal or spatial absolute and relative displacements .
Geodesic methods are most commonly used in practice, and they are divided into the following categories:
