WebWhere a shear wall contains no openings, the computations for deflection and rigidity are quite simple. In Fig. 10(a), the shear walls are of equal length and rigidity, and each takes one half of the total load. In Fig. 10(b), wall C is one half the length of wall D and it, therefore, receives less than one eighth of the total load. Where shear hrsrs.comWebJun 30, 2024 · This is the most common form of shear wall in US buildings.
