Abstract

In a companion paper, a simplified method for the evaluation of the slab construction load was developed. Unlike existing methods, the proposed method includes the effects of shore stiffness and concrete cracking on the construction load. In the present study, construction loads were measured in actual flat-plate slabs. For verification, the measured shore-forces were compared with the predictions by the proposed method and existing methods. Further, the proposed method was applied to a wall-slab structure, and the prediction results were compared with the measurements. The comparison results showed that the proposed method well predicted the construction loads, furthermore it gave better predictions than the existing methods did.

연계 논문에서는 슬래브의 시공하중을 산정하는 간략화한 방법을 개발하였다. 기존 방법과 달리, 제안 방법은 동바리 강성과 시공하중에 의한 콘크리트 균열 효과를 고려할 수 있다. 이 연구에서는 실제 플랫 플레이트 슬래브에서 시공하중을 계측하였다. 제안 방법의 입증을 위하여, 계측된 동바리 하중은 제안 방법과 기존 방법으로 예측한 결과와 비교되었다. 또한, 제안 방법은 기존 연구에서 측정된 벽식 구조에도 적용되었고, 예측 결과는 계측 결과와 비교되었다. 비교 결과, 제안 방법은 시공하중을 잘 예측하였고, 기존 방법에 비해 더 우수한 예측 결과를 보여주었다.
