Solving the previous example from full iteration Now it’s time to solve the previous example from full iteration. For simplicity, interaction with flexure is not considered. In other words, it is assumed that the status is in a pure shear c...

Findings and remarks 1. We can calculate the feasible crack angle ranges for each εx and vu/f’c combination. θ min corresponds to concrete c...
Optimum crack angle θ From the previous example, we can catch that there are some possible crack angle ranges for the given εx and vu/f’c. N...
Longitudinal reinforcement Believe it or not, longitudinal forces are caused by shear, and we do need to design/check for these longitudinal...
Concrete Shear Equation The concrete shear equation is
In the FEM, the most critical question is “how many meshes do we need to get the correct (or reasonable) results?”
Continuing on to the third part of this multi-part blog, another option is a quadrilateral element. As always, let’s start with an example.
For the previous example, we can use high-order triangular elements. This element has six nodes per element and assumes the displacement is ...
