There's a lot to be said for a mechanical interference that prevents two things from moving relative to one another. Like say a bolt, in shear (or a pin). Better still is a bolt that exerts clamp force, thus leaving it far, far less in shear. Bolts are amazing and I can't see why people think glue is better. Welding is better, sure, but it's also a lot more permanent.
EDIT: I get why people like glue for things like carbon fiber bikes, etc because weight is an issue and you can't really bolt it. But for buildings? That's a different use case.

- JoBrad 11y agoI can't speak for other materials, but for wood, a properly glued joint is far superior to fasteners. The glue combines the wood at the molecular level, so that the two pieces are one. There are similar glues for plastics, too. I don't know about metal and mortar, but if such a thing exists, using it would be much better than bolts or screws. The one drawback is that, if you have to replace a portion of a structure that is glued, the process is necessarily destructive. You can limit the destruction, but you still have to cut the old piece out. It doesn't seem like this would generally be a problem with buildings, though, as almost every type of renovation is destructive.

- WalterBright 11y agoMechanical fasteners are easily inspected. Welded and glued joints, not so much.
