A building with a height of more than 40 meters, which is said to be the tallest wooden structure in Japan, has been completed in Yokohama city.
Wooden skyscrapers are expected to have the effect of reducing carbon dioxide emissions associated with construction.
The 11-story building with a height of 44 meters was completed in Naka-ku, Yokohama.
The main structures such as pillars and beams are made only of wood, and according to the major general building company Obayashi Gumi, the main structure is only wood under the current national earthquake resistance standards. It is the tallest building.
It is explained that the pillars and beams are strengthened by stacking three boards each, and that the building will not be damaged even at a seismic intensity of 7 by applying special waterproofing to prevent expansion due to rain.
Wooden buildings are expected to have the effect of reducing carbon dioxide because the amount of concrete and iron used for construction is greatly reduced, and the company estimates that carbon dioxide emissions will be higher than when similar buildings are made of reinforced concrete. It means that we were able to reduce the amount to about a quarter.
Amid the demand for decarbonization efforts, the technology to improve earthquake resistance and fire resistance has improved, and in Tokyo Ginza, a 12-story building that combines wood and steel frames has been built, and wooden structures are being built in various places. Building plans are being made one after another.
Shinji Yamazaki, director of Obayashi Corporation, said, "Since decarbonization is attracting attention, we would like to aim for the construction of wooden condominiums and hotels in the future."
