+20 elements doesnt explain things.

That said, it sounds like you've built too high without proper structural support. As electric said, you're going to most likely need to build with iron beams but even then you may have issues depending on your design.

You will probably have to use iron reinforced wooden beams. They will help you build bigger and taller.
