| Abstract: | Temperature cracks on concrete perforated brick masonry walls are discussed. The effects of strength of concrete perorated brick and mortar,section height of ring beam and difference in temperature of structure on temperature stress are considered. The computmional model is set up by using ANSYS programme,and then the temperature stress of the model is analyzed by finite element method. The effects of some affecting factors on temperature stress are summ arized. Some valuable conclusions have been obtained ... |
