Cracking in Walls
This chapter focuses on the calculation of cracking in walls subject to a shear force; the calculations may also be applied to beam webs and caissons. First, walls subjected to quasi‐static forces are considered. The chapter discusses cracking under the effect of earthquakes that is addressed. Inclined cracking implies that the shear stress in the horizontal plane exceeds a certain criterion, for example, the principal stress exceeds the tensile strength. The state of strain and stresses in a wall rarely result in a 'simple' calculation, and structural effects usually dominate in determining strain and stress distribution. It is therefore necessary to use either a traditional wind bracing calculation or finite element modeling in order to evaluate the stresses and strains. The calculation of crack spacing in walls subject to membrane shear forces is based on the use of virtual ties in the vertical and horizontal directions.
