| Abstract: | In order to study temperature crack mechanism of masonry structure, temperature field of the masonry structure wall and roof panel was surveyed and the temperature distribution with time of masonry structure wall and roof panel was acquired. The varied temperature field of masonry structure is presented. On the basis of studying temperature field, the whole structure stress distribution was analyzed with the finite element method and the computing procedure of temperature stress considering the effect of material shrinkage was obitined. It is useful for controlling temperature crack in masonry structure. |
| Keywords: | masonry structure temperature field temperature stress finite element method |
