The first article of the blog is dedicated to loads. The primary function of a bridge is to support loads, for example a truck that has to cross a valley. For this reason, the truck load can be defined as a primary load.
A list of loads includes:
- Self-weight of the structure;
- vehicle weights;
- horizontal vehicle loads (centrifugal force, braking, etc.);
- weight of pedestrian;
- wind loads;
- earthquake loads;
- thermal effects;
- collision forces.
In next articles I’ll try to go more in details with all of them. For the moment, let’s keep it simple and close here the post.
