Abstract
The dynamic behaviors of the roof of the Gymnasium 2 of Yoyogi Stadium are reported on the basis of elastic response analyses. Firstly, the static analysis has been carried out, and the results are compared with the values reported elsewhere. Secondly, the eigenvalue analysis has been carried out, and the resulting natural periods are compared with those measured on the actual roof. Finally, the elastic response analyses have been carried out. The response accelerations in the horizontal and the vertical directions are compared at the corresponding points of the roof. The dominant natural modes for different load directions are pursued from the distribution of the maximum response acceleration, and the stress states of the suspended roof trusses are examined.
