Reverse engineering is a methodology used to extract vital structural information from existing constructions, employing it for assessing load-carrying capacity and structural safety. The data collected encompasses structural dimensions, detailing, and mechanical properties of materials. Utilizing this information to formulate numerical models of structures, the structural analysis through the finite element method, coupled with the computed structural cross-sectional force and moment resistances, contributes to determining the load-carrying capacity. This, in turn, serves as an indicator of the safety level of the structures.
Why Reversed Engineering?
Certainly, the anticipated result of engaging in reverse engineering is the evaluation of safety, achieved by comparing the calculated strength of structural members with the actual internal forces occurring in those members. These forces are induced by the applied loads in accordance with the requirements outlined in building or bridge design codes. The following are reasons why reverse engineering is necessary:
– Changes in load intensity or load patterns (alteration in area function)
– Absence of structural information (lack of structural drawings and engineering calculations)
– Structural damage (material deterioration, fire, blast, overloading)
– Construction errors
