| Abstract: | Stone curtain wall was adopted as external decoration of a building, but cracks appear on the slab slot of the stone curtain wall after several years. With the purpose to verify safety and reliability of the stone curtain wall, the dry-hanging stone structure of the external wall is tested on site and whole tri-dimensional finite element mechanical calculation is made. The structure is strengthened and maintenance measures are proposed on basis of analysis on reason for the cracks on slab slot and evaluation on the safety. |
