    Casting a concrete beam at half.

    Thanks for the answers. I've been trying to find in the ACI Manuals something about this. And have been unable to find it. I'm trusting the engineer who designed the structure. But my civil engineer side wants to wants to learn more about this. For example, how many stirrups should you...

    Casting a concrete beam at half.

    Hi. At work I'm currently preparing for casting a slab, and the following doubt arised. One of the beams is a 1m tall beam which starts from the slab and goes up. The slab is a "waffle slab" of 20cm thickness. The engineer which made the structural design, told us that it is OK to first cast...

    RC Beam. Are they always considered to be fixed?

    Yes, in the case I'm seeing the RC members would be build in-situ. Meaning you place the steel reinforcement and then cast the concrete in-situ. My doubt started when I saw that the final design of this rectangular room, had more steel reinforcement in the bottom of the beam. When, if the...

    Sorry. It would be a 3-span beam.

    RC Beam. Are they always considered to be fixed?

    Thanks for the answers. Would this change if the construction has two levels? Meaning that the beam is between the first level column and the second level column. And lastly, in the case JAE commented about. When you have a continuous beam (for example a 4-span section) you consider the...

    RC Beam. Are they always considered to be fixed?

    Hi, I have a doubt regarding RC beams. If you are building a rectangular room, which has 4 columns (one in each corner) and 4 beams, how should you proceed with the analysis of the beams? Should I consider them to be fixed-fixed? My guess is that this is the correct answer, but I'm not 100%...
