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


Based on the test series of Reference 20 (high axial load ratio), the I^sub e^ becomes equal to I^sub g^, and for a wall tested in Reference 18, the I^sub e^ again becomes inconsistent with the test results. 4. (3) or (4) leads to an overly conservative design for the practicing structural engineer and will not be a cost-effective design, especially for high-rise reinforced concrete buildings.
