1.CIP D=450 CTC 450 H-300x305x15x15 (파일간격 1.80M)
2.CIP D=400 CTC 400 H-250x255x14x14 (파일간격 2.00M)

두가지에 대해서 환산한 연속벽체로 계산을 했을때 계산상으로 1번의 경우가 더 불리하게 계산이 됩니다. 일반적으로 CIP 공법의 경우에 연속벽으로 계산한후에 각각의 벽체가 휨과 전단에 대해서 저항할 수 있도록 설계하는데 환산단면으로 계산할 경우에 CIP 천공직경이 클수록 I 값이 커지게 되서 데이터 결과값이 차이가 나게 됩니다.
결과 값만 비교하자면 2번이 설계상에서는 유리하게 되는데 이값을 신뢰할 수 있는지에 대해서 알고 싶습니다.
