Identification of causes of warehouse collapse

The design of the warehouse should fully consider factors such as load, structural strength and stability. If the designer fails to take these factors into consideration, the warehouse structure may be unstable and prone to collapse. Especially in harsh environments such as earthquakes and storms, design flaws are more likely to be exposed.
During the construction process of the warehouse, quality supervision of construction specifications is very critical. If the builder fails to carry out construction and quality supervision in accordance with the specifications, it may cause the warehouse building structure to be unstable and lead to collapse accidents. Especially the construction quality of key parts such as foundation layers, columns, and beams often has a crucial impact on the structural stability of the entire warehouse.
In the case of warehouse collapse cause identification, Zhongke Testing can provide warehouse collapse cause identification services.

1, design defects
The design of the warehouse should fully consider factors such as load, structural strength and stability. If the designer fails to take these factors into consideration, the warehouse structure may be unstable and prone to collapse.
2. Irregular construction
During the construction process of the warehouse, quality supervision of construction specifications is very critical. If the builder fails to carry out construction and quality supervision in accordance with the specifications, it may cause the warehouse building structure to be unstable and lead to collapse accidents.
3, overloading
In the construction and use of warehouses, overloading is a very common problem. If the warehouse exceeds the design load, the warehouse structure will be overstressed, causing problems such as tilting and breakage, accelerating structural fatigue and leading to collapse.
4, environmental factors
Environmental factors are also one of the factors leading to warehouse collapse. For example, natural disasters such as typhoons, floods, earthquakes, and unexpected factors such as fires may affect the warehouse structure and lead to collapse accidents.

The person in charge of a company rented a warehouse in the suburbs as a temporary storage point for beer. One night, the warehouse suddenly collapsed and most of the stored goods were smashed. The lessee suffered serious losses.
was entrusted by the person in charge of the warehouse to conduct an appraisal and analysis on the cause of the collapse of the warehouse involved.
appraisal analysis results: The
appraisal analysis expert team inspected the warehouse and found that the warehouse was older, its walls were made of brick-concrete structure, the walls and mezzanine structure were aging, and the weighing capacity was limited. After inspection, it was found that there was also a horizontal crack in the load-bearing wall, which was later repaired. According to the quantity of goods on site, it exceeded the carrying capacity of the warehouse, which eventually led to collapse.
To sum up, the warehouse is old, the mezzanine brackets are not strong enough, the weighing wall has cracks that have not been fully repaired, and the goods are overloaded, causing the warehouse to collapse.
