Analysis and Discussion of Wall Cracks in a High-rise Building
With a high-rise building in Taiyuan as an example,an investigation of the actual distribution of cracks was conducted by statistical means to explore the causes of cracks on filling walls of a high-rise building and to prevent worsening of cracks.The results showed that wall damage appeared in a non-load-bearing structural member(filled wall)and that crack type mainly included vertical cracks between aerated concrete block(filling wall)and concrete shear wall(bearing wall),cracks on a wall pipe,as well as cracks under the window corner and the partition wall(non-load-bearing members).These cracks did not affect the safety of the main structure,but they might cause local wall leakage,glass cracking,physical appearance and most important-ly,decreased serviceability.Therefore,the paper proposes that wall cracks should be closed to a-void the erosion of rain leakage to the wall and give preventive suggestions to improve the quality of wall structure.
