For measuring the crossmember/outrigger web sideways deformation, which area should be referenced?

The most appropriate area to reference for measuring the crossmember/outrigger web sideways deformation is the undamaged area. This is because the undamaged area serves as a baseline for comparison, allowing for an accurate assessment of any deformation that may have occurred. By evaluating measurements against this area, you can determine how much the crossmember or outrigger has been affected by external forces or impacts.

In a practical sense, if deformation is measured against an area that has sustained damage or distortion, it could lead to misleading conclusions about the structural integrity of the component. The undamaged area provides clarity on the original configuration of the web, making it easier to quantify the extent of deformation accurately. This method ensures that the evaluation reflects the true state of the structure without the influence of prior damage.
