倒塌 (dǎo tā): (빌딩의) 붕괴

That old house collapsed in the storm, but luckily no one was inside at the time.

After the earthquake, many bridges collapsed, and the rescue team had to take a detour.

Due to years of neglect, the ancient pagoda at the village entrance could collapse at any time.

The flood washed away the foundation, causing this building to eventually collapse.
