Yes.. But we were talking about varying panel thickness in a RC&S board to achieve the same stiffness as a CC board.... so my point holds. Ron O writes >Ric B writes: /So varying panel thickness to achieve similar stiffness would />/probably insure dissimilar mass. / Varying the panel thickness, to achieve a certain level of stiffness, has been the most usual method of controlling stiffness for the CC building school. The hysteresis loss matter, which Sarah raised, is an interesting one as well.
