Extreme stress of bending test specimens.

Specimen number	Extreme stress of steel plate (location) (MPa)	Extreme stress of concrete (location) (MPa)	Notes
SC-M1	36.8 (midspan)	−6.85 (0.75 m)	Without joints
SC-M2	43.6 (1.5 m)	−4.88 (1.25 m)	With joints
SC-M3	39.7 (1.25 m)	−5.81 (0.75 m)	With joints

Note: permissible stress value for Q345 steel plate is 310 MPa (less than 16 mm)/295 MPa and for C40 concrete 19.1 MPa (compression)/1.71 MPa (tension).
