Japanese experts point out that China's building seismic standards are low.

< P > < FONT face = Verdana > Japanese media published an article on May 20 saying that about 26.78 million houses collapsed and damaged in the Sichuan earthquake in China. Although there have been major earthquakes in the past, China's building seismic standards are less than half of Japan's, and many older buildings are said to have lower seismic strength. Some experts believe that it is necessary for Japan to teach China advanced earthquake-resistant technology.

< P > < FONT face = Verdana > The current seismic standard in Japan varies depending on the strength of the foundation and the structure of the building. According to the Ministry of Land, Infrastructure, Transport and Tourism, the basic standard is to withstand an earthquake acceleration value of 300 to 400 gal. The acceleration of the Great Hanshin Earthquake is 800 gal.

< P > < FONT face = Verdana > Yan Kong, a professor of earthquake engineering at Capital University in Tokyo who is familiar with China's earthquake prevention situation, said that China formulated seismic standards for buildings in various regions in 2001, with 200 gals in Beijing and 100 gals in Shanghai. Sichuan Province, where the earthquake occurred, has a lower standard of 100 gals in Chengdu and only 50 gals in Chongqing, Mianyang and Deyang.

This technology is reinforced by wrapping polyester fiber tape around the pillars of the building. Tuan Jiyan has sent an e-mail through the Japan-China Exchange and Culture Association to express his desire to provide technology, and it is said that the Chinese side has written back to say that it will study it.
