The most common pathology that causes the main maintenance and durability problems in steel structures is corrosion, since it causes the loss of material from the beams that form the structure, diminishing its properties and therefore the general resistance of the structure. After cleaning the corrosion on a beam, its surface becomes very irregular and it is very difficult to measure and extract the geometry of these shapes and surfaces manually. To this end, laser scanning and its subsequent point cloud is a promising method. The objective of this work is to show how obtaining beam models with extruded slices of one beam affected by corrosion for subsequent analysis structural from the laser scanning. The proposed steps were applied and validated in laboratory study cases.
