A Study of the Vibrational Characteristics of Two Multistory Buildings.

摘要

Forced vibration tests and associated analysis of two multistory buildings (the Millikan Library on the California Institute of Technology campus, a nine-story reinforced concrete shear wall building;and The Ralph M. Parsons World Headquarters building,Pasadena,California, a twelve-story steel frame structure) are described. In one case,the dynamic properties of the building measured during tests are compared to those predicted by simple analytical models. A three-dimensional finite element model of the second building was constructed for the purpose of evaluating the accuracy of this type of analysis for predicting the observed dynamic properties of the structure.
