Increase of service life of ferro-concrete columns of the operating industrial enterprises
Abstract: Difficulty of reuse or recycling of failed ferroconcrete designs forms the basis for increase of service life of such designs by their strengthening. The main precondition of successful work on strengthening of designs is the correct estimation of initial data about condition of the object, carrying ability and reasons of damages. On the basis of analysis and generalizations of data on inspection of maintained objects, there have been considered basic combinations of defects of columns. The calculation of a residual resource of column with defects influence and constructive decisions on strengthening were carried out by means of the program “Construction superintendent”. Analysis of technology of strengthening with the use of materials of conducting world manufacturers is executed. The different methods on the basis of working budget norms estimation of cost, strengthening and columns are given. Character of influence of defects of ferroconcrete columns on the cost of works for their strengthening is established.
Keywords: service life, defects, residual bearing ability, strengthening.
