Lateral load tests were conducted with crushed dimensions as experimental variables for the purpose of investigating the maximum lateral strength and bending moment equation for RC columns in demolition.
1. Percentage of Maximum lateral strengths tended to decrease as the amount of crushing in the depth direction increased.
2. Experimental values of the maximum Lateral strength at disassembly can be estimated using the proposed bending moment calculation equation. When calculated using the average of the crushed cross sections and the length of the neutral axis of RC columns determined by theory, the proposed bending moment equation adequately evaluates the experimental values.
3. The length of the neutral axis of RC columns determined by theory tended to increase with increasing depth of crushed for the same crushed height direction. Those values ranged from 43% to 57% of the column depth.
