Load testing of building components or elements is a popular means of demonstrating a structure's capabilities when a simple analysis is not practical. Typical situations that arise include :-

• strength unknown
• change of use
• bomb or fire damage
• materials defect (cube failure)
• suspect performance
• routine verification of lifting equipment

A variety of loading techniques can be applied according to the weight required, the condition of the building and logistical limitations. Water and kentledge are the most popular methods.

Monitoring of deflections is undertaken either electronically or using dial gauges, other qualities may also be measured such as crack widths, strains and temperature.
