| dc.description.abstract | Indonesia is a country that has vulnerability to an earthquake. This is because Indonesia
located in the Pasific earthquake area (Circum Pasific Earthquake Belt) and Asiatic earthquake
area (Trans Asiatic Earthquake Belt). During the earthquake, the building has vertical and
horizontal motion. Horizontal earthquake forces attack the weak points on structure that not strong
enough and caused collapse building. To reduce the losses and casualities caused by the collapse
of building especially multistory building, many seismic analyzes of structures are developed. In
general the analysis divided into two type, there are static equivalent and dynamic analysis. The
dynamic analysis divided into response spectrum and dinamic time history analysis.
This research explained the comparison of structural response between response spectrum
and dynamic time history analysis to an irregular 9-story building. The building located in
Yogyakarta with medium soil type and used as a hotel. The earthquake record that used for dynamic
time history is El Centro 1979 earthquake (high frequency), El Centro 1940 earthquake (medium
frequency), and Duzce earthquake (low frequency). Furthermore, the maximum result of structural
response between them will be used for design purposes. The analysis in this research was done by
ETABS version 9.6.
The result showed that the maximum value of structural response such as displacement,
story drift, momen force, shear force, and axial force caused by El Centro 1940 earthquake load.
The next value caused by response spectrum load, Duzce earthquake load, and the smallest value
caused by El Centro 1979 earthquake. The design calculation was done by using the result from
dynamic time history analysis that caused by El Centro 1940 earthquake load because the load has
the maximum response value. | en_US |
