| Abstract: | Design of Reinforced Concrete Beams with rectangular Cross Sections against biaxial Shear Forces An approach is presented to design reinforced concrete beams with rectangular cross sections and usual stirrups against shear forces that act inclined to the principal axes of the cross sections. It basis on the “truss model with crack friction” and adds supplementary terms to the equations of the shear resistances acc. to DIN 1045‐1 to take account for shear force inclinations. Verifications to experimental as well as numerical data are given. An example shows that resistances evidently decrease – or higher amounts of stirrup reinforcement become necessary –, if shear forces deviate from principal axes. |
