In concrete design per the ACI code, if the size of the concrete beam member which I am designing is limited and I need to have 2 rows of reinforcement in the top or the bottom of the beam, how do I input this request? Or Does Staad automatically output the data with the second row? have been trying to find this in the Manuals. I have seen LEVELS BUT IT DOES NOT SAY WHAT I NEED.
You do not have to input any special request. As long as the section can be designed as a singly reinforced section (reinforcement in the tension zone only), STAAD will try to fit the bars in up to 2 layers. For each layer, the distance from the bottom of the section is reported. The number of bars required for each layer too is reported. It reports a failure only if more than 2 layers are required.
