Abstract
The high building modern is hoped can support neccesiaries of human activities on the building. So the building must strong and save from the broken, especially because of the quake. Because the quake is dynamic load that work on the building of the way oscillation.pondation fastly. Commanly, the dinamic respons from structure cann’t be explained MEMADAI with a model of SDOF, the respons usually include times of variation from the shape of moving and also the amplitude. That characteristic can be explained into more than one coordinate shape of moving, so that the analyse protection to the quake of the building that influence to the simple spectrum oscillator of ideal condition will conatant vibrate with constant amplitude to the natural frecuency is considered with as the mainting from the vibrate. The analyse of accounting to get point w (natural frequency) and Ø (normal mode), is used stodola method. And helped by computer program STAAD Pro 2004. The natural frecuention that emerged by structure when the quake was happening of the smalles displacement point. So, from the result of evalution can be known the ideal point to the displacement (x) smalles happen to portal III of necessaries frame 16D25 = (x) = 1.472 mm, so that a slim colom dimention used displacement of structure smaller it means if smaller displacement happen to the structure isn’t broken because a small quake or medium, but when the quake strong was happening the structure of dactail.
