Question

A shear wall in a reinforced concrete building is subjected to a vertical uniform load of intensity q and a horizontal force H, as shown in the first part of the figure. (The force H represents the effects of wind and earthquake loads.) As a consequence of these loads, the stresses at point A on the surface of the wall have the values shown in the second part of the figure (compressive stress equal to 8 MPa and shear stress equal to 3 MPa). (a) Determine the principal stresses and show them on a sketch of a properly oriented element. (b) Determine the maximum shear stresses and associated normal stresses and show them on sketch of a properly oriented element.

Problem 7.3-9 A shear wall in a reinforced concrete building is
subjected to a vertical uniform load of intensity q and a horizontal
force H, as shown in the first part of the figure. (The force H repre-
sents the effects of wind and earthquake loads.) As a consequence
of these loads, the stresses at point A on the surface of the wall have
the values shown in the second part of the figure (compressive
stress equal to 8 MPa and shear stress equal to 3 MPa).
