To accomplish this, strain patterns in suitably modified steel shear walls with slits are studied. The modifications introduced to the slit configuration were determined by means of FEM analysis. From the strain history obtained, yield zones were recorded as black and white pictures. The picture was later fed to an artificial neural network to associate each pattern to a drift angle. Analysis results were satisfactory with an accuracy of 0.25%. Paint is suggested for the purpose of identifying the strain zones in the slit walls. The strain induces flaking in the paint, leaving patterns that can be associated with different drift angles. Qualitative characteristics such as brittleness and a consistent strain-stress relation are desirable in the paint. Coupon test results confirm the viability of the use of paint as a recording method.
