It is reported that exterior materials such as a double-folded plate roof are damaged affected by wind load or thermal load. Particularly, as a double-folded plate roof is used for a long span, their displacements by thermal expansion are large. It is necessary for design and construction to reduce damage in roof joint strength caused by cyclic thermal expansion.
This paper shows behavior of a double-folded plate affected by thermal expansion which the building structure were constructed. First, basic data such as temperature and displacement of a double-folded plate roof are investigated. Furthermore, cyclic test of specimen of the double-folded plate roof is conducted and simple analytical model to evaluate lateral displacement of the double-folded plate roof by thermal expansion is proposed.
