EFFECT OF CRUSHED DIMENSIONS ON LATERAL LOAD STRENGTH CAPACITIES OF MULTI-LAYERED REINFORCEMENT CONCRETE COLUMNS IN DEMOLITION WORKS

In order to propose a calculation method for the calculated lateral load strength capacities in the demolition works of multi-layered reinforcement columns and to estimate the location of the neutral axis, lateral load tests were conducted on RC column specimens with the crushed dimension as experimental variables. As a result, by using the proposed calculation formula for the maximum lateral load strengths obtained from the experimental values, the difference between the calculated and experimental values were within 15%, and the calculated values correctly evaluated the experimental values.
