Seismic Engineering Technology Changing the Face of Architecture

Abstract eng:
Since the beginning of times architecture has been used as an instrument to demonstrate political and economic power, so architects have been looking to create spaces and buildings that amaze people. Technology has been one of the most important features that have allowed architects to achieve these goals: taller buildings, greater cantilevers, asymmetry in structural topology, etc. Seismic engineering has evolve in a short period of time, developing structural systems and seismic devices that help architecture and engineering to create new solutions in seismic zones, such as: shear walls frames, moment resisting frames, concentric and eccentric brace frames, base isolation systems, elasto-plastic and visco-elastic dampers, metallic yielding dampers, hydraulic external pre-isolators, magnetorheological fluid dampers, etc. These devices and systems, with the use of computational advances for different types of seismic analysis, help to create spectacular buildings in seismic zones, changing the face of architecture and the image of the cities in which they are built. The aim of this paper is to analyze through time the development of different seismic structural systems and the seismic devices which dissipate seismic energy and how their presence in the structural design of iconic architectural buildings all along the world has made possible their dreams in seismic zones.
