Abstract

This research investigated the effect of solar radiation on the temperature distribution in concrete mat foundation. Zhang and Huang Model was utilized to estimate solar radiation heat at a given date and time. A one-dimensional finite element formula was derived with the fundamental laws of heat transfer and Galerkin method. Based on the formula, a one dimensional finite element analysis code was developed using MATLAB. Hydration heat analysis of mat foundation were conducted using the developed code. It was found that the solar radiation reduced the maximum temperature difference in mat foundation, and this temperature difference reduction was more prominent in case of summer season cast, a higher initial concrete temperature, and a thicker mat foundation depth. The research recommended that the solar radiation should be considered in hydration heat analysis of concrete mat foundation so as not to overestimate the maximum temperature difference in mat foundation.

태양 복사가 콘크리트 매트기초 내부 온도 분포에 미치는 영향에 대한 해석적 연구를 수행하였다. 태양복사량 산정을 위해 Zhang and Huang 모델을 사용하였다. 열전달 방정식과 Galerkin 방법을 이용하여 1차원 열전달 유한 요소 정식화를 수행하였으며, MATLAB을 사용하여 유한요소 해석코드를 작성하였다. 작성된 해석코드를 바탕으로 태양복사를 고려한 콘크리트 매트기초의 수화열 해석을 수행하였다. 해석결과, 태양복사가 매트기초 내부-표면부 최대온도차를 줄여주는 효과를 보임을 확인하였다. 또한 이러한 효과는 하절기 타설시, 콘크리트 초기온도가 클수록, 그리고 매트기초의 두께가 두꺼울수록 더욱 뚜렷해짐을 확인 하였다. 본 연구는 콘크리트 매트기초의 수화열 해석시 해석결과의 과대평가를 피하기 위해서 태양 복사의 영향을 고려해야 함을 권고한다.
