Many buildings in earthquake prone regions of the world are vulnerable to structural damage resulting from slow creep of movement of earth. Thus, could it be possible that modern buildings incorporate strain gauges and pressure sensors for understanding the vibrations within the building due to wind effect, ground movement, or inherent oscillations of the building?
When coupled to automated logging by computers, such sensors could serve to chronicle the movement of the buildings and warn of possible structural damage from various factors, or, more importantly, it can serve as early warning of impending danger to the building and its occupants from a structural breakdown of the building. In earthquake prone regions, buildings with inbuilt pressure sensors and strain gauges could be able to inform structural engineers of the fine level movement within each floor of the building; thereby, highlighting areas in need of maintenance or reinforcement. The information obtained could also be used in designing next generation buildings able to relieve the in-built pressure and strain of a building, and its interaction with wind and possible ground movement.
Thus, strain gauges could highlight structural deficits of buildings, and serve as a source of information for post-mortem analysis of building failure modes in earthquakes.
