摘要
本文通过算例 ,应用有限元方法计算在温降荷载作用下混凝土的应力分布 ,并应用断裂力学方法研究由此引起的表面裂缝问题。结果表明 。
This paper presents an example for analysis of temperature stresses of concrete during temperature drop by the Finite Element Method, and for research on the temperature crack of concrete surface by means of fracture mechanics. Some results show that it is not sufficient to judge cracking of concrete and stability of cracking only by comparison between the temperature stress and the strength of concrete.
