m is the ratio of the steel modulus to the concrete modulus. When doing transformed sections m is used to "transform" the steel area into equivalent concrete area. The reason for the m-1 is that when the steel area is expanded in an un-cracked section the steel area inside the concrete needs...
I am designing a new slab foundation to be poured adjacent to an existing slab foundation with an expansion/isolation joint separating the two. The issue is there will be loading going from one slab to the next and I would like there to be shear transfer between the two so that as the load...
