ABSTRACT

In this study, small scale "hands-on" experiments were conducted on a model wooden frame structure under dynamic effects. The base excitation was applied to the specimen by a "home-made" shaking table which was designed and developed within the scope of the graduation projects of civil engineering students. The device is capable of producing harmonic motion at the base level of the model structure. Two alternative structural systems were designed and constructed namely rigid frame and flexible frame. Displacement responses derived from the tests were compared with the linear time history analysis. The analytical model is capable of capturing the achieved displacement values. In the second part of the study, harmonic tests were performed on the frame structure which was instrumented with small scaled seismic isolation devices. Seismic isolators were selected as pendulum bearings which are installed between the structure and its foundation in order to isolate the supported structure from harmonic excitations. Design of structures with the friction pendulum technology is cost-effective, since the isolated structure behaves elastically during the seismic motions without any structural damage. The base isolation device having the characteristics of a pendulum tends to increase the natural vibration period of the isolated structure with the reduced dynamic forces. The test results showed that displacement and the acceleration responses of the isolated structure were significantly reduced.
