| Abstract1 |
본 연구에서는 충전각형강관 말뚝과 지하건축벽이 결합된 합성지하벽의 휨강도 산정을 위한 설계방법을 제시하였다. 합성지하벽에 토압작용시 토압의 대부분은 낮은 강성의 비합성된 말뚝들을 통하여 건축벽으로 전달되므로 말뚝과 건축벽의 휨강성 차이에 의해 두 부재 사이에는 벌어짐 변형이 발생한다. 이에 따라 전단연결재에는 계면을 따른 전단응력뿐만 아니라 인장응력이 발생하게 되므로 이와 같은 접합부 계면의 상태를 반영할 수 있는 휨강도 계산과정을 제시하고 실제 실험결과와 비교하였다. 그 결과 계산된 내력이 실험결과와 좋은 대응을 보이는 것으로 나타났다. 따라서 이 계산과정을 통하여 충전강관말뚝과 RC벽이 사이에 벌어짐변형이 발생할 경우의 합성지하벽 휨강도를 적절히 예측할 수 있을 것으로 판단된다. |

In this study, a design method for estimating the flexural strength of a composite underground wall in which a filled square tube pile and a
building basement wall were combined was presented. When earth pressure is applied to the composite basement wall, most of the earth
pressure is transmitted to the building wall through low-rigidity piles not combined with the basement wall. Flexural deformation between the
two members occurs due to the difference in the flexural stiffness between the not combined pile and the basement wall. Accordingly, since
tensile stress as well as shear stress along the interface are generated in the shear connector. An flexural strength calculation process that
could reflect the state of the interface of the joint was presented and compared with actual experimental results in this paper. As a result,
when the composite ratio was less than 100%, it was found that the filled square steel tube pile and the RC wall behaved completely
independent under the consideration of the joint opening. In this case, the sum of each independent flexural strength was found to be close
to the actual experimental results rather than the flexural strength by composite action. The calculated moment showed good correspondence
with the experimental results. Therefore, through this calculation process, it is possible to predict the flexural strength of the composite
basement wall in case opening deformation occurs between the filled square tube pile and the RC wall. |
