- The following photos (extracted from the reconnaissance report on the Chile 2010 earthquake by Prof. J. Moehle) to illustrate that, in this case, where the static approach was used, the collapse of the building occurred due to the high forces induced, the stress concentrations, and the high ductility demand that have resulted from the presence of irregularities in the vertical structural system (an offset to allow access to the underground parking level) that have not been be detected or identified.

- Other selected photos (extracted from reconnaissance reports by others following recent earthquakes) of typical failures in new building constructions, to show that these have resulted mainly from the inadequate evaluation of earthquake induced forces, primarily related to the deformation of the structure, the degradation of structural elements' strength caused by the large inelastic deformations, and/or the high ductility demand expected during these events, that have not, and could not be properly evaluated when relying on the sole static approach.
