20 questions about structural design principles

1. What does designing with high-strength steel involve?

Designing with high-strength steel involves selecting the appropriate steel grade and optimizing the material properties and design geometry to achieve better performance and lower weight. Well-designed high-strength steel structures can withstand higher stresses than comparable mild steel structures, resulting in increased strength and durability.

2. How is the design "rule of thumb" used?

The design “rule of thumb” considers stress levels of a plate in bending. Mostly, it is conservative for other components with respect to elastic load carrying capability. Be aware that the stiffness is reduced when working solely with thickness reduction according to the rule of thumb. Stability and fatigue are phenomena that the rule of thumb does not consider, and these need to be addressed specifically. It is important to note that the rule of thumb is not applicable for all components, particularly those subjected to deformation limits, stability issues and fatigue loads.
