Abstract

The quality of social service offered by the country has been improved since recently recurring economic progress and sharply proceeded industrialism ; apparent quality of military building has also been evolved as economic growth. However, schism made by old fashioned barracks generally degrade the quality of life for soldiers therefore, the loss of ability to perform battle is also occurred. As a result, the Ministry of national defense has been reconstructing or maintaining the current facilities to move forward to well-developed military bases. Especially, researches and efforts for eradicating crack in the walls in barracks are really going on. This research aims to assess and organize the cracks made at military facilities, find the factor in researched material, then analyze its causes and finally figure out the main cause of the problems. The causes offered by this are elapsed years, lintel, the direction of wall, size of facility, stairs, wall material, structure of the wall, pollution level of the environment, look of roof, rainfall, non-frost days, average temperature, inside temperature, the number of entrance and the location of the building. The following is the conclusion. 1. Taking a look at the relation in between the clefts and their causes of in barracks, elapsed years effect is 79%, lintel effect is 73%, the direction of wall effect is 66%, stair effect is 59%, size effect is 59%, the material effect is 55% and structure effect is 47% respectively, orderly, and this says that all the factors above referred are generally effect the problems. 2. Inside temperature and pollution level of the environment have tiny effect on the schism as their decisional coefficient records 0.03% and 0.16% and the coefficient of weather condition and direction and location of walls and were 0.04% and 0.3% respectively and this says that the relation between above referred factors and the schisms is hardly showed. 3. As result of backward analysis for each independent variables which have high reliabilities -elapsed years, lintel, direction of the wall, stairs, the material, structure and size-, decisional coefficients of each categories record 0.9799(97%) and this says that the referred is closely related the cleave. To sum up, the cracks in the barracks have high dependence on carry-out condition offered artificial factor. This is applied not only for military facilities but also general buildings made by concrete. So permanent research for figuring out the exact causes of the cracks must be keep going and then more developed carry out method which minimizes the cracks, should be invented.
