| Abstract: | Characteristics of concrete (RC/PC)beams with large openings in strength,rigidity,deformation,and cracking are studied amply by experimental and theoretical analysis.A calculating method of beams with large openings is given.It is shoun that results of testing coincide with results of calculating ,and that can be used in engineering designing. |
| |
| Keywords: | concrete strength rigidity cracking and openings. |
