摘要
Estimating shear wall and diaphragm deflection is important for several reasons, including (1) classifying diaphragms as rigid or flexible; (2) estimating intrastory drifts to compare to code specified limits; and (3) estimating the potential for excessive deflection, which may cause costly damage. Historically, shear wall and diaphragm deflection has not been a critical design consideration. Much more attention has been paid to this issue after the 1994 Northridge, Calif. earthquake. The Northridge earthquake caused designers and code officials to place more emphasis on deflection, specifically for classifying diaphragms as either rigid or flexible. Building code changes that limited the use of narrow shear walls were also a result of the Northridge earthquake. Although building codes have provided methods for estimating diaphragm and shear wall deflection, this information is scattered and incomplete. The intention of this paper is to provide a comprehensive summary of the currently recognized methodologies for calculating shear wall and diaphragm deflection. © ASCE.
