<p>The Japanese pavilion at the 2010 World Expo in Shanghai is a large space structure 100m in the longitudinal direction and 50m in the transverse direction. The shape is not a regular geometric shape, but is a special shape. This structure with its special shape was planned to have a high structural performance, taking into consideration economics, the short construction period, and ease of construction. The following is a description of the structural design.</p>
In order to investigate the lateral shear performance of newly developed wooden grid shear wall, full-scale static test by repeated shear loading was carried out. The beam and column members were made of Japanese cedar and the wall was partly reinforced by plywood. As a result, the wall didn't reach ultimate strength even at 1/7.9(rad) of deformation angle, and it was confirmed that the wall had a high ductility capacity which was derived from plastic rotational embedment resistance of joint parts. The simple evaluation method of the wall was suggested. It was confirmed that the method was appropriate, comparing with the result of the experiment.
<p>The Suita Stadium is a football-dedicated stadium with a seating capacity of 40,000 currently under construction in Suita, Osaka, Japan. Its large-span roof is characterized by the 3D (three-directional) mega truss structures and the seismic isolators supporting it from the top of the stand structure. In this paper, the structural design processes for the Suita Stadium are introduced featuring seismic response analysis, wind tunnel test and response analysis, and structural optimization.</p>
