A full-scale five-story steel frame building was tested dynamically by means of a servohydraulic-type vibrator to evaluate experimentally the soil-structure interaction effect. The test building consists of 6 pieces of isolated concrete footings, a five-story steel frame and concrete slabs. It is 15m long in E-W direction. 3.75m wide in N-S direction, and 17.4m high as shown in Fig. 1. A servohydraulic-type vibrator instead of a centrifugal-type vibrator was used to force the building and footings to vibrate. The building was subjected to horizontally incident SH or SV waves generated from two different reinforced concrete model footings. They were 4m long, 4m wide. and 1m high, and placed at a distance of 16m south and 30m east from the building. We carried out tests over higher frequency range more than the second mode of the building. Fig. 3 shows the building response for the second mode in NS direction subjected to horizontally incident SV waves generated from S(south) footing. Table 2 shows the effect of excitation at different footings on the resonant frequency and damping ratio of the building. From the experimental results, it is found that the soil-structure interaction effects of the building evaluated by forced vibration at the first floor are in good agreement with those evaluated from response of the building subjected to horizontally incident SH or SV waves generated from the model footing.
