Hello,
for long span beams ranging between ( 15m to 20 m), which is better to use steel beams/frames or use post tensioning concrete beams ?
Thanks

They can be either steel or concrete.

Where you are located plays a large role in choice mainly due to material availability and skilled worker availability. Whether you are in a seismic zone or not also plays a factor.
You can't ask which is better because the answer is both, and it could be neither.

If it's a roof, then steel. If it's a floor, match the material used elsewhere in the building. There are lots of exceptions of course.
We can be more helpful if you share more detail about your building. Where is it? What is the occupancy? How many stories? What materials are used elsewhere in the building? Is it all comprised of these long spans?
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Its a University building of 4 storey and its located in the Gulf Region.
Spans in one direction are ( 20m,10m and 5m)typical for all floors
Concrete is the material used for other members
