What we mean by repair construction?
The repair is carried out in structures that are damaged by an earthquake and have judged episkeuásima. In Case the damage to the structure (Skeleton) of a building is widespread and serious the building comes down. Repairs are concern so the structure of the building and the infills (walls). Depending on the extent of damage and the element that repaired selected and the type of repair to be held. The Repair of a construction suffered damage in an earthquake does not ensure avoid them in a future earthquake, during which the new lesions may be greater. In buildings where except infills developed and non expected damage by earthquake in their structure, checking for possible strengthening them is necessary in order to avoid unpleasant (potentially devastating) results from future earthquakes.
What is the strengthening of construction?
The term aid refers to the procedures to be followed in order an existing building, designed before the introduction of modern earthquake-proo
f regulations, upgraded adequately and to be able to withstand a big future earthquake which is expected in the region where is built. These procedures vary depending on the characteristics of the construction, the demands placed to meet after the upgrade and other factors.
Because most of the time the studies of calculation of an old design and construction is difficult to detect, need accurate apotímisēs capacity of the existing structure. The Civil Engineer is therefore invited to first thought the carrying capacity of the existing structure and then proceed to redesign of, so as to be compatible with the requirements of modern earthquake-proof regulations.
The Load-bearing aid may be carried out before an earthquake or after him, if the degree of damage of construction is such that allows the repair and enhancement and does not impose the demolition of. The frequency of devastating earthquakes in our country and the threat to the lives of the residents of old buildings (which constitute 70 % of the buildings in our country) clearly highlight the need earthquake inspection of buildings that have built before 1980 ( At least), In order to take place in time the strengthening them and to avoid future crashes and fatalities.
