Example of Cracking Moment for a reinforce concrete t-beam
This construction video is based on reinforced concrete design. Here an example problem is solved that is related to the cracking moment.
Learn the process to work out the cracking moment concerning a reinforced concrete t-beam as well as verify whether the beam or cross section is cracked because of the functional load.
The Cracking Moment is also called as Mcr. If the moment is raised over Mcr, the tensile stresses in concrete at the tension zone are extended unless they become larger than the modulus of rupture fctr, and it results in developing of cracks.
This moment is essential to discover which Moment of Inertia will be applicable at the time of measuring Deflection.
