Test of High-Rise Core Wall: Effective Stiffness for Seismic Analysis. Paper by Perry Adebar, Ahmed M. M. Ibrahim, and Michael Bryson

(ProQuest: ... denotes formulae omitted.)

The authors have presented an interesting concept on the effective stiffness of core/structural walls. The discusser would like to offer the following comments:

1. The authors have proposed Eq. (3) based on a limited test series of walls having an h^sub w^/l^sub w^ ratio equal to or greater than 3.0. Also, walls in the references studied by the authors were rectangular, except for References 9 and 12, which cover walls having end boundary elements and T-shaped walls. It was very difficult to determine the effective stiffness of a wall with a T-shape due to the loading patterns. Also, three walls in Reference 11 have a staggered opening, which ...
