7.1.4 Openings at Shear Walls

California Administrative Code 2019 > 6 Seismic Evaluation Procedures for Hospital Buildings > 7 Procedures for Diaphragms > 7.1 Diaphragms > 7.1.4 Openings at Shear Walls
JUMP TO FULL CODE CHAPTER
Diaphragm openings immediately adjacent to the shear walls constitute less than 25 percent of the wall length, and the available length appears sufficient.
For conforming buildings, the evaluator may consider this condition as mitigated, and no calculations are necessary. The deficiency is in the length of diaphragm needed to transfer shear to the wall or frame and to provide lateral support for the wall or frame.
Procedure for diaphragm shear: Verify that there is a path of forces and sufficient strength to deliver the diaphragm shear to the shear wall. The diaphragm shear is the demand.
Procedure for lateral support of the wall: Treat the wall as a portion of the building using Fp as the demand.
