具有日本特色的体育场,与周围的明治神宫森林融为一体–新国家体育场的外观以多层 “屋檐 “融入了日本特色。屋檐是日本传统建筑的一个组成部分,是根植于日本气候的一种既定结构。它们通过阻挡阳光并为看台带来舒适的微风,为创造环境友好型建筑做出了贡献。

Stadium with Japanese-ness, blending in with the surrounding Meiji Shrine forest – The exterior of the new National Stadium integrates Japanese-ness with multilayered “eaves.” Eaves are a component of traditional Japanese architecture, an established structure rooted in the Japanese climate. They contribute to creating environmentally friendly architecture by blocking sunlight and bringing a pleasant breeze to the stands.

此外,为了与明治神宫外苑丰富的绿色植物融为一体,体育场的高度被降到了最低,屋檐上还种植了本地物种。大型平屋顶是悬臂式的,由约60米长的国产木材和钢材制成的框架组成。这个世界级的体育场结合了日本的传统、气候和技术。

Furthermore, in order to blend in with the rich greenery of the Meiji Shrine’s Outer Garden, the stadium height is minimized and the eaves are vegetated with native species. The large, flat roof is cantilevered, consisting of frames about 60m-long made of domestic wood and steel. This world-class stadium combines Japanese tradition, climate and technology.

通过利用风改善看台的热环境–“风之大檐 “通过有效地引入季节性的风,同时通过顶部去除体育场内的热量和湿度,改善看台和场地的热环境。屋檐上的格子之间的间距(开口率)根据建筑物的方向而变化。南-东南侧较窄,以捕捉夏季的微风并将其引向看台,而北侧较宽,以在冬季分流风并将其引向屋顶内部。

Improved thermal environment for the stands by utilizing wind – “Kaze no Obisashi (grand eaves of the wind)” improves the thermal environment of the stands and field by effectively bringing in seasonal wind, while removing the heat and humidity from inside the stadium through the top. The spacing (opening ratio) between the lattices on the eaves varies according to the direction of the building. The south-southeast side is narrower to capture the summer breeze and direct it to the stands, whereas the north side is wider to divert the wind in the winter and direct it inside the roof.

追求卓越的结构性能和可操作性–为了在有限的施工期内达到卓越的质量和耐用性,悬臂式屋顶和看台由简单的钢架构成,由相同的结构在圆周方向上重复。基础和观众席大量使用了预制材料。采用软首层阻尼结构,软首层带有油阻尼器,有效地吸收了地震能量。

Seeking superior structural performance and workability – In order to achieve superior quality and durability within the limited construction period, the cantilevered roof and stands are constructed of a simple steel frame, made of the same structure repeated in the circumferential direction. Precast materials were heavily used for the foundation and spectators’ seats. Employing a soft-first-story damping structure, the soft lower level with oil dampers effectively absorbs earthquake energy.
