Moment-curvature relationships to estimate deflections and second-order moments in wind-loaded RC chimneys and towers
Devdas Menon
Abstract
Second-order moments of considerable magnitude arise in tall and slender RC chimneys towers subject to along-wind loading, on account of eccentricities in the distributed self-weight of the tower in the deflected profile. An accurate solution to this problem of geometric nonlinearity is rendered difficult by the uncertainties in estimating the flexural rigidity of the tower, due to variable cracking of concrete and the
