It's amazing to see how the structures intertwine.
The foundations transmit the loads to the soil, the columns relay the loads to the foundations, and in turn, the beams transmit their loads to the columns.
Today I'm going to show you what is done to calculate a beam using this reduced model.
Hey engineering lovers, my name is Igor Felipe, and if you already follow our channel, you know that we've already made other videos talking about structures, and today we're going to talk a little about beams.
Come on, the beams are structural elements that transmit their loads to the pillars or support points.
It is important to understand that when we connect the foundations, with the pillars and beams, we assemble what we call a portico.
This gantry works together, where each and every load alters not only one but all connected elements.
It is important to understand these frames, as many people like to analyze the structures in isolation, calculating item by item separately, but once interconnected, the loads change the behavior of the structure as a whole.
For example, if we apply a load to the side of this pillar, see that the whole set changes and triggers a series of loads in various directions and elements.
We will have several loads caused by this simple applied load, and this shows us that once interconnected, the structure works as a whole.
The same happens if I apply a load in the center of this beam.
The beam will be suffering what we call bending, the columns will receive reactions from this beam with vertical loads, which will transmit these loads to the foundations.
The entire set works because of just one load, and that same load can generate other loads if we change the lattices or the structure's crimps, but that's a topic for another video.
But come on, we can have several vertical loads on the beams.
They can receive punctual loads along their length, they can receive distributed loads, which are loads equally distributed along their length, and they can also receive variable loads, which can vary according to their length.
