QUESTION: What is the difference between Vmu and Vu ?

ANSWER:

Vmu and Vu are 2 different entities where

Vmu = Factored shear occurring simultaneously with Mu .Basically shear is based on where the max moment is occurring, generally the shear value is less than Vu.

Example - Truck load in the mid span of the beam

Vu =Total factored shear force at section . Shear is based on where the max shear occurs .

Example - Truck Load is placed at the starting or end of the span
