Abstract |
This study, we design two sky bridge lower connecting devices to be installed on three buildings with a maximum height of 56 stories (200 m).The safety of the sky bridge is examined when an earthquake load occurs by applying a lower connecting device. As a result of examining the safety of the lower seismic isolation device of the sky bridge installed in buildings 101 and 102, the maximum displacement of the seismic isolation device was found to be 67.9 mm. The relative displacement with respect to the lower column of the seismic isolation device was 145.9 mm. In addition, the relative displacement with the upper bridge of the seismic isolation device was 125.9 mm. This result was shown to be safe as it did not exceed the maximum allowable displacement value of 150 mm for the seismic isolation device. As a result of examining the safety of the lower seismic isolation device of the sky bridge installed in buildings 102 and 103, the maximum displacement of the seismic isolation device was found to be 23.4 mm. The relative displacement with respect to the lower column of the seismic isolation device was 78.3 mm. Additionally, the relative displacement with respect to the upper bridge of the seismic isolation device showed a displacement of 65.4 mm. It was found that the maximum allowable displacement of the seismic isolation device did not exceed 150 mm. The seismic isolation devices installed in the three buildings are considered safe against seismic loads.
