There might be several reasons for this and to answer it properly, I need to investigate the model, Can you upload your STAAD model and also mention the build number of STAAD that you are using?

Hi, i am facing a issue that slab reinforcement shows none why?

I think its better to design Column and beam once, then slap

Hi sir , i have a qstion

How to design beam and slab simultaneously in staad

If i give floor load plate wont be considered

If i give plate load that won be transfered to beam (plate not meshed to get descent ast ) is there a way to get proper design of beam and slab in staad

hello sir suro i have a question regarding the sq.in/ft. ratio, can you please elaborate more on this, for example if on this design the reinforcing steel that i going to be use is #3 bars what would the spacing be? i dont understand the output... the part that has (top : 0.130) <--------is this the ratio? and what is it for? thanks in advance

Can anyone please explain how can I design columns and beams by taking results from a solid model i have generated in staad.

Thank you very much. Now it's all been cleared to me.

Hi,

It is because, minimum reinforcement governs in this case. The moments on the slab are too small to warrant any steel requirement to resist flexure. As the minimum steel is adequate, so program displays a message as:

478 TOP : Longitudinal direction - Only minimum steel required.

Minimum steel percentage is based on Clause 7.12.2.1 of ACI 318. If you increase the loading, reinforcement percentage will increase accordingly.

If the plate is finely meshed, then there will be more number of internal nodes for which the program calculates the displacement and stress values. A fine mesh will always have better results, but will simultaneously increase the run time and the volume of data. So, the mesh size should be based on an optimization between the accuracy required and the run time.

Thank you for your help. What does 'only minimum steel required' mean? Was surface meshing necessary in this case?

Hi,

To design a concrete slab in STAAD.Pro, you need to add the DESIGN ELEMENT command. In your model, you have specified the command and program designs all the plate elements. The reinforcement details are reported in the output file as shown in the following figure:
