Will tall buildings collapse in the earthquake? A tall building shook in Changzhou earthquake 12 seconds.

Earthquakes are common natural disasters every day. Many people have experienced earthquakes, but now there are more and more tall buildings in our lives. Will high-rise buildings collapse after the earthquake? Did the Changzhou earthquake shake tall buildings 12 seconds? Many friends want to know the answer to this question. Let's have a quick look.

Experts believe that the higher the building, the more dangerous it is. An earthquake of magnitude 8. 1 occurred in Mexico, but the tallest building in Latin America was hardly damaged, and most buildings in the city from 10 to 15 were damaged. In this regard, experts analysis, from the perspective of the structure of high-rise buildings and multi-storey buildings, one is a frame shear wall structure, and the other is a brick-concrete structure. In terms of seismic performance, because the design level of shear wall is much higher than that of brick-concrete and frame, it has high seismic capacity from the structural system. Of course, there must be strict requirements for the construction team and materials. Experts believe that when an earthquake happens, the house will shake and deform to a certain extent, but in terms of deformation ability, the high-rise building we live in now has stronger resilience and should be safe.

A tall building shook in Changzhou earthquake 12 seconds. According to the official measurement by China Seismological Network, an earthquake of magnitude 4.2 occurred in Tianning District, Changzhou City, Jiangsu Province (3 1.75 degrees north latitude and 0/20.00 degrees east longitude) with a focal depth of 10 km. After the earthquake, a short video on the Internet about "the tall building keeps shaking 12 seconds" attracted people's attention. Some netizens said after reading it: "It's terrible, so scary!" Some netizens are very calm and rational analysis thinks: "It doesn't look like the building is shaking, isn't it a camera?" Zheng Jianhua, director of the Science and Technology Monitoring Department of Nanjing Earthquake Administration, told the reporter that the building was not shaking, but the camera was shaking. After preliminary verification, no casualties and property losses caused by the earthquake have been found. According to the judgment of the Seismological Bureau of Jiangsu Province, it is unlikely that a bigger earthquake will occur in the original earthquake area in the next few days. At present, the fire department of Changzhou has not received any early warning about the earthquake. After the earthquake, the Changzhou Fire and Earthquake Rescue Team assembled in an emergency to conduct pull drills and deal with related emergencies. At present, no reports of casualties have been received. According to residents, the earthquake in Tianning area of Changzhou is obvious, and houses and lamps are shaking to varying degrees. Some high-rise residents ran out of the building to avoid danger. The reporter saw at the scene that some residents in pajamas ran down from the tall building in one breath. Many residents report that animals in their homes bark and have other abnormal conditions. At present, the relevant social order is stable.

There is no such rule whether high-rise buildings are easy to collapse or low-rise buildings are easy to collapse during an earthquake. In the same area, the seismic grade of high-rise buildings and low-rise buildings is the same. However, in terms of material strength, the high-rise building with reinforced concrete structure with good construction quality has stronger integrity and seismic capacity than the low-rise building with brick-concrete structure. When the earthquake happens, the house will shake and deform to a certain extent, but in terms of deformation ability, the high-rise building we live in now has stronger resilience and should be safe. No matter which floor of a high-rise building, its structural safety factor is the same. From the stress point of view, the lower the floors in high-rise buildings, the greater the stress. Because the high-rise building is a structure embedded in the ground, all floors will be subjected to seismic force during the earthquake, and the seismic force will spread from high to low to lower floors. Therefore, it is not the lower the floor, the higher the safety.

How to escape from high-rise earthquake and save yourself? Once an earthquake occurs, it is extremely important to keep a clear head, identify the vibration in time, and never jump off a building in panic. Secondly, you can hide under solid furniture, or in a corner, or you can move to a kitchen, toilet and small room with many load-bearing walls for temporary shelter. Because these places have strong binding force, especially the pipeline has good supporting force and large seismic coefficient after treatment. Choose the inside of the load-bearing wall in the house and take refuge in a small room. Remember not to hide on the side of the outer wall near the window. It is definitely not the best policy for residents living in high-rise buildings to jump off buildings during the earthquake.
