Hawke's Bay Earthquake Case Study

1187 Words5 Pages

ABSTRACT
The ground shaking induces vibrations in the structure and the resulting deformations can cause significant damage and possibly collapse of the structure. Dynamic analysis can be used to determine from the acceleration records of ground shaking the maximum accelerations, velocities and displacements imposed on various elements of a structure. The ground shaking can result in deformations of the ground that cause damage. One example is landslides in sloping ground. Another is relative movement along and across surface fault lines and uplift, each of which can be up to several meters. For example, the Hawke’s Bay earthquake of 1931 caused nearly 2 meters of permanent uplift a Napier.The Time History Response of a structure is simply …show more content…

In present case Response spectrum analysis is performed and the results are compared in four different zones with 7m 4 bay length. The results of the analyses, in terms of lateral deformations, respective storey drifts and base shears are obtained and the conclusions are drawn.
Key words: Base Shear, deflection, storey drift, Bending moment, Shear force, Stability of indices and cost …show more content…

STRUCTURAL SYSTEM
The development of structural systems for tall buildings can be traced back to William LeBaron Jenny, in 1885. This combined with the invention of a safe passenger elevator by Otis in 1854 led to an explosion of high-rise buildings. In the ensuring 28-year period from 1885 to 1913, the first generation of skyscrapers culminated with the erection of Chrysler Building in New York in 1930, immediately followed by the Empire State Building in 1931, which held the record as the world’s tallest building for 41 years.
The second wave of tall buildings began in 1956 based on new building technology and new concepts in structural design, climaxing in 1974 with the completion of Sears Tower, a 110-storey, 1450-ft tall building in Chicago. Following the Sears Tower, the post second generation of super tall buildings has included only “mixed” construction, consisting of both steel and reinforced concrete. The 1476-ft Petronas Towers, built in Kuala Lampur, Malaysia in 1997, and the 1667-ft tall Taipei 101 building, which attained its full height in

In order to have built these buildings they had to have the right resources, such as cheap, high quality structural steel. Goodheart describes all the different inventions that had to come before the skyscraper, such as the elevator. When the elevator was first invented by Elisha Graves Otis in 1854, he would rise above crowds on an open platform of wrought iron.
