In Hailuogou, the epicenter, two hotel buildings collapsed! Will the frame structure also collapse?

In Hailuogou Scenic Area, the epicenter, two hotel buildings all collapsed. Seeing this situation, netizens questioned whether the frame structure houses would also collapse. The answer is yes, the frame structure can only improve the seismic capacity, but can't guarantee the absolute earthquake resistance. With the increase of earthquake magnitude, the destructive power is also increasing. In the face of natural forces, we humans will be as fragile as paper when building with smart construction.

In the Luding earthquake, two hotel buildings collapsed in Hailuogou Scenic Area, which were not frame structures. The main body of the hotel is a wooden structure, and brick walls can be seen through the live pictures. To be exact, it belongs to? Brick and wood structure? More appropriately, the seismic capacity of this structure is much worse than that of the frame structure. The hotel is six stories high, which will reduce its seismic capacity.

Frame structure houses can improve the seismic capacity, but they can't resist all earthquakes. Since the Wenchuan earthquake, frame-structured houses have become the most commonly used structural way to build houses in Sichuan. So-called? Frame structure? , that is, cast-in-place reinforced concrete is used as the load-bearing structure of the house. In most cases, the wall will be filled after the house frame is erected.

Frame structure houses enhance the seismic performance of houses, but cannot make houses have the ability to resist all earthquakes. In the face of an earthquake of magnitude 8 or above, poor quality frame structure houses may also collapse.

The overall building quality of the collapsed hotel is good, and the supporting capacity of the bottom floor is insufficient. Most of the collapsed hotels are made of wooden materials, which also reflects the characteristics of the hotel. Although the hotel collapsed, only the first and second floors were damaged, and the upper floors were still intact. It can also be seen from here that the construction quality of the hotel is qualified. Unfortunately, the foundation support may not be strong enough to make the hotel collapse in the earthquake.

If the foundation support columns are laid well and clean concrete is chosen during construction, perhaps the two hotels can resist earthquake damage.

Therefore, the frame structure can improve the seismic performance, but it can't guarantee that it can withstand a big earthquake without falling down. Compared with ordinary houses, the frame structure is stronger and has stronger earthquake resistance.
