| Abstract: | Temperature cracks and some cracking mechanisms of concrete perforated brick masonry are discussed.Finite element analysis is done for overall structure under temperature load in order to research the rules of deformation and stress distribution under temperature difference.According different influence factors, some different finite element analysis models are established and different influence factors of temperature cracks are analyzed.Based on finite element analysis and references,some effective measur... |
