Abstract:

After an industrial brick cylindrical silo structure was put into use, multiple vertical cracksappeared on the outer silo wall. On⁃site detection was carried out on the cracking condition of thestructure and the material strength. The circumferential tension borne by the silo wall at different heightsand the circumferential bearing capacity of the silo wall were calculated. Comprehensive analysis showsthat: The silo structure design has significant defects, and the insufficient circumferential bearingcapacity of the silo wall is the main cracking cause. Based on the above results, this paper proposes areinforcement treatment method,which involves casting a reinforced concrete shear wall structure on theinner surface of the original brick silo wall to replace the brick silo wall in bearing the circumferentialtension caused by stored materials. Through analysis and calculation, it is ensured that thecircumferential bearing capacity meets the requirements.
