The girder is cracked and cannot be broken. There are many reasons for cracks in girders. If it is a turtle-shaped crack with uniform size and regular shape, it will not do any harm to the wall, because the cement slab and putty on the beam will produce cracks in different degrees, which will not affect the overall result. If it is a relatively long single crack, it is probably caused by heavy objects. As long as the width of the crack is between 0.2 and 0.3 mm, it will not break.
