Structure
What we build must stay in place for as long as the building exists. It must be built in such a way as to resist all the weather can throw at it, the movement of the planet, and what ever loads we apply via people, equipment and operation. This series of lectures takes a look at structure and how we as technologists apply it to our designs and detailing.
Structures have to put up with a lot, this video shows just how good the suspension bridge is taking a large coach and distributing the load.
