Hi
Choosing the most basic and effective parameters as the subject of your study on the behavior of RC hollow core beams could be most dependent on the type of your study like Experimental, Finite Element and analytical. Ductility, Loading mechanism and fracture mechanics could be your subject of the study. I think you should describe more of your goals .
Sincerely
