In this paper, the structural safety of RC building with damaged elements is evaluated by using a simple analytical method during dismantling. The structural safety of the building according to the variation of column damage is especially focused since the damage normally governs the overall safety of building. As a method, sectional analysis for the damaged columns and other elements using X-Tract program and structural analysis using MIDAS Gen are performed.
From the analysis results, the structural safety of the building for working loads during dismantling can be obtained even if stiffness of a column in the building decrease until 50%. Negative moment of beams, which are connected to the damaged column, change to positive one when the damage rate of column is to be serous. Therefore, opposite end moment of the beams rapidly increased.
