A bottleneck that most structural engineers face when designing buildings in earthquake-prone areas is the vagueness of just how earthquake-proof the prospective structure should be; this is because earthquakes vary in magnitude and causes, ranging from deep openings in the earth’s surface to severe disturbances across a fault line. To test each structure, create a lateral shaking movement using the same distance of displacement you previously measured. Torre Reforma, which stood second in the Emporis Skyscraper Awards last year is the tallest building in the city and rises to a height of 809 feet. Designing a building to have lateral resistance is helpful not only for preventing quake damage, but also from other lateral forces, such as wind. But what about more violent forces, such as those produced by earthquakes? Architecture
If some fell and others did not, what were the differences in height between these towers? Those coupling beams play a critical role in helping a skyscraper withstand the effects of an earthquake. Engineers will probably combine traditional dampeners with the plate because it doesn't protect against all types of waves, yet it could be particularly useful in areas where waves traveling horizontally are more destructive, such as parts of Seattle and San Francisco. A base isolated structure is supported by a series of bearing pads which are placed between the building and the building’s foundation. A well-planned and tested design, when combined with the right materials, can keep a building intact through all sorts of shakes and quakes. The Taipei 101 skyscraper needs to withstand typhoon winds and earthquake tremors common in this area of Asia/Pacific.

I would be much more concerned about the design of the building and how well the builders did their job rather than the shape of the building. Buildings in the country have been built to be earthquake proof, and construction focuses on deep foundation and massive shock absorbers to dampen seismic energy in the event of an earthquake. The tallest skyscraper of San Francisco, the Transamerica Pyramid stands at 835 feet with phenomenal earthquake resistance capabilities. Base isolation technology can make medium-rise masonry (stone or brick) or reinforced concrete structures capable of withstanding earthquakes, protecting them and their occupants from major damage or injury. Today's engineers buffer buildings with metal springs, ball bearings and rubber pads, all designed to sop up the energy from seismic waves. For this purpose, a steel pendulum weighing 660 metric tonnes that serves as a tuned mass damper was designed and installed atop the structure. Next year, engineers will test a two-foot-wide model of the design, and the tech could be on both new and old buildings as early as 2014. This development, along with other innovative ideas and materials, allowed for the creation of skyscrapers—and as our technologies continue to improve we are be able to reach ever closer to the sky.
