THE CAPACITY OF SHORING MAY NOT BE WHAT YOU THINK

Image result for Shoring failure during concrete placement

Following a collapse during concrete placement, an investigation concluded that the cause of the collapse was a stability failure of the shoring elements supporting the wet concrete.

The analyses and testing that was performed following the collapse focused on details of the shoring system, which were found to be common within the industry. The findings show that these common details result in the inability of shoring systems, analyzed or tested, to achieve their stated load capacities.

This presentation will discuss the collapse, the initial investigation and, the results of three full-scale laboratory tests performed on common shoring towers. The presentation will show how common details decrease the capacity of shoring systems, how such detailing can be avoided, and point out other potential hazards.
