Most building collapses are shaken and broken up by lateral oscillations caused by transverse waves. The existing building is mostly shockproof by adopting a building body reinforcing mode, such as a ring beam structure, and such as a cast-in-place mode. These measures reinforce the building body to a certain extent, but it is still difficult to resist earthquakes with an intensity of up to 11 degrees in shocks like Wenchuan.
