Stress evaluation of prestressed concrete beam based on
To effectively evaluate the actual stress level of prestressed concrete (PC) beams in service, the stress assessment method of prestressed tendons in PC structures after cracking is proposed based on incompatible deformation of the cracked structure and the stiffness reduction model. The stiffness reduction model of the cracked beam is …
8 Types of Column Failure Methods
As per the British standards, concrete is capable of carrying a strain up to 0.0035 and steel starts yielding at a strain of 0.002 and it can increase greater than the concrete. When the axial stress exceeds a certain amount resulting in concrete strain grater than 0.0035 concrete will fail suddenly. It will be a sudden crushing of concrete.
