The 1997 UBC Section 16220.127.116.11.1 indicates the values for Rp and Ap of 3.0 and 1.5 respectively should be used for elements of the wall anchorage system. What are the components of the wall anchorage system that these values apply to? Is it the attachment of the wall to the diaphragm. Or does this also include the subdiaphragms and cross-ties? if hx = hr ==> Fp = ap*Ca*Ip/Rp*(4Wp) = 1.5 * (.44*1.2) * 1.0 / 3 * 4 * Wp = 1.06Wp This seems high to me. If anyone could take the time to clarify/confirm this, it would be appreciated. Thanks in advance. Joseph M. Otto, PE Ireland Engineering Fremont, CA
