Causes Investigation and Analysis for the Overall Collapse of the Steel Structure Awning
The overall collapse accident of a steel structure awning was investigated,and the causes of the awning collapse were analyzed based on the results of data investigation,on-site testing and bearing capacity verification.The connection nodes between the awning structure and the main structure is not pre-anchored according to the requirements of the design drawings,and there are many construction defects,the bearing capacity of the anchor nodes before the structure is not transformed does not meet the requirements of safe use,the load of structural transformation is increasing,and the bearing capacity of the structure is further reduced by the aging of the anchoring glue in the process of use,which causes the bearing capacity of the anchor nodes to be seriously insufficient,and finally leads to the collapse of the awning.
