Load Testing and Stability of Concrete Shoring Towers

Presented By:  Kerry Kreitman, Ph.D., Pivot Engineers


An in-service collapse of a concrete shoring system prompted an investigation and load testing of shoring towers. Preliminary analysis indicated that the commonly-used beam-over-column detail, which was not considered in the design, may have contributed to the cause of the collapse. This was confirmed through the experimental testing, in which a reduction of the ultimate load capacity of the tested shoring tower was reduced by approximately 40% due to the presence of the beam-over-column detail.


Kerry tackles structural issues and explores their solutions with her colleagues at Pivot Engineers. Her adventures in structural forensics began as a graduate student at UT-Austin where she investigated nondestructive testing techniques for evaluation of concrete material issues as well as helped develop a method of strengthening existing steel bridges. Her professional experience is widespread across the industry from interstate bridges to academic buildings to power generating centers, from steel to concrete to aluminum and other materials, and from aging structures to new construction.
