Dynamic Properties of McKINLEY School Buildings
The behavior of a structure during an earthquake depends on both the characteristics of the ground motion at the structure's foundation and the dynamic properties of the structure. Therefore, knowledge of dynamic properties is essential for aseismic design. A primary motivation for conducting dynamic tests on real structures is to determine the damping capacity, and, in structures where suitable idealization is difficult, to determine mode shapes and natural frequencies. The ultimate objective of these tests is the accumulation of a body of information on the dynamic properties of typical examples of each class of structure. A unique opportunity arose to conduct dynamic tests on single-story timber buildings when the McKinley School had to be vacated. Typically, the buildings had three basic modes of vibration designated transverse, longitudinal, and flexure of the roof diaphragm. It is concluded that the dynamic response of these modes to earthquake excitation can be predicted adequately by means of a linear viscously damped mathematical model. (Author)
