The picture shows that the famous scenic spot of Kumamoto City, Kumamoto Castle Tenshogaku, was damaged in the earthquake.
26 P. M. local time on the 14th, a shallow earthquake measuring 6.5 on the Richter scale with a focal depth of 11 km occurred in Kumamoto Prefecture, Kyushu, Japan. Since then, aftershocks have continued to occur, causing 41 deaths, more than 10 people lost contact, more than 3000 people were injured to varying degrees, and about 100000 people were evacuated to various shelters.
A netizen of our website sent a photo of a building after the earthquake. From the photo, we can see that although the building was torn in the middle after the earthquake, it did not collapse. Netizens broke the news that the houses in the epicenter of the Kumamoto earthquake adopted the principle of expansion joints to strengthen the seismic function, and only broke, not collapsed, to minimize casualties when encountering strong earthquakes.
Compared with Japan, China still has a lot of work to do in the earthquake resistance of buildings, and the past debts need to be made up. Recently, according to media reports, 50 deputies to the National People's Congress in Shanxi Province jointly proposed: seismic reinforcement and energy-saving renovation of existing buildings. In the 1980s and 1990s, a large number of five-or six-storey brick-concrete structure houses were built in China, which basically had no seismic design or low fortification level. At the same time, it is out of repair for a long time, the aging of common buildings is serious, the safety and comfort are low, and the willingness of residents to improve their living conditions is relatively high. According to incomplete statistics, the area of such housing in China is 14 billion m2. Most of these houses are located in the central area of the city, in the current situation of high housing prices, the cost and cost of relocation and construction of new houses are unbearable. Accelerating the seismic reinforcement of such existing buildings and implementing green energy-saving renovation should become a new way of real estate transformation and a new growth pole of the economy, which urgently needs the guidance of the government.
At present, China's building seismic technology is also constantly improving, and the Ministry of Housing and Construction's vigorous promotion of high performance concrete and high performance concrete products also provides a guarantee for building seismic performance. In recent years, various new technologies and products have emerged, such as earthquake-resistant and crack-control concrete, high-performance concrete earthquake-resistant piles, etc.
The Ministry of Housing and Urban-Rural Development (MOHURD) recently issued a notice that it will continue to ensure the seismic fortification capacity of construction projects in 2016. The first is to organize and carry out the inspection of seismic fortification capacity of high-rise buildings in some areas, promote the informationization of special review of seismic fortification of high-rise buildings, carry out supervision and inspection of seismic mitigation and isolation projects, and steadily promote the application of seismic mitigation and isolation technology. Second, in conjunction with the Development and Reform Commission and the Ministry of Finance, we will continue to intensify reconstruction of dangerous houses in rural area, accelerate the improvement of laws and regulations on rural housing construction and related technical safety standards and standards, strengthen supervision and technical guidance, and improve the ability of rural housing to resist earthquakes and mitigate disasters. Third, we should actively promote the organic renewal of old urban residential areas and promote the seismic reinforcement of existing housing construction projects. The four is to implement the new version of the zoning map and promote the seismic fortification work in the original non-fortification areas.
