Predicting the shear behavior of reinforced concrete beams with Fe-Based shape memory alloy stirrups
Engineering Structures（2023）
摘要
•Activated Fe-SMA stirrups reduced the number of diagonal shear cracks in RC beams.•Precompression force due to activated stirrups had little effect on shear strength.•Precompression force due to activated Fe-SMA stirrups improved the shear stiffness.•Section analysis predicted the shear behavior of RC beams with Fe-SMA stirrups.
