Unformatted text preview: Problem 5-3 (5 points) The strong motion station at Arleta is inside a fire station. Assume you are designing a replacement 2-story, steel-moment-frame fire station building for that site. The building will be approximately the same size as the existing building (use Google Earth to estimate the area of the existing building if needed). Assume 5% damping. Assume that there are no horizontal irregularities. Develop the CBC (IBC2006) design spectrum for the building . List your assumptions & calculations needed to develop the design spectrum. Plot your design spectrum along with the earthquake motions measured during the 1994 Northridge Earthquake. Discuss the differences, especially at the estimated period of the new building. Assuming a repeat of the 1994 Northridge ground motions, how do you think your new building would perform?...
