Adisorn Owatsirwong, D.Eng. This equivalent nodal force is opposite to Fixed-end reactions and written in the element force calculation as follows. {Fe} = [ke]{u} - {q} {q} = Equivalent nodal force When assembling the element stiffness, those {q} are summed into the global load vector {F}, i.e. {F} + {Q}= [K]{u} [F] = Nodal applied load {Q} = Sum of equivalent nodal load vector [K] = The global stiffness of the structure MATLAB Code (case qe = q) function feq = eqv_load_dro

Shear reinforcement in a concrete beam is required when the shear strength of concrete alone is inadequate to carry the vertical shear from external loads. ACI 318 stipulates the general equation for computing the vertical shear strength of a concrete beam with inclined stirrups as follows. Vs = As*fy*d/s*(sin(a) + cos(a)) where a = horizontal angle of the inclined stirrup It's first astonishing to see the term cos(a) for the shear strength of the stirrup, which should only b
