Abstract:
Governing equations for the normal stresses due to wind and dead load are derived for the case where a concrete chimney cross section is weakened by four openings located at the same level, and symmetric to the axis along the wind direction. Results are obtained for the conditions where the neutral axis of the section lies within as well as outside the openings. Other limiting cases where the geometry and number of openings are varied are discussed,
