EARTHQUAKE-RESISTANT STRUCTURES




Earthquakes in the past few years have rocked the world, causing any number of deaths and destruction, the magnitude of which far exceeds that caused by man-made world wars. It rests on the shoulders of engineers more than anyone else, to find engineering solutions to resist them and mitigate their ill effects. This is possible through science and technology by developing seismic-resistant structure designs governed by effective seismic building codes.

Earthquakes are a global phenomenon associated with the formation of earth billions of years ago. Discontinuities and faults in the earth’s crust cause physical changes and tectonic plate movements that result in vibrations and oscillations in the foundations of buildings, bridges, dams, and other structures. Earthquakes often create tsunamis caused by seismic movements of ocean beds.

Seismic-resistant design is a relatively new subject that is now being studied and carried out on a scientific basis. It is also being taken very seriously at the international level. One area of investigation, particularly in less-developed countries, is to make structures seismically safe at reasonable cost.
