Abstract:
Design and construction practice for typical cast-in-place concrete and precast concrete domes used to cover large water and wastewater tanks are described. Available dome thicknesses required for adequate buckling resistance of uniform cast-in-place concrete spherical domes, precast concrete domes with various joints, and ribbed concrete domes are given. Stress resultants for membrane and edge-bending effects are summarized for the usual types of loading. Experience from condition surveys of old concrete or shotcrete domes is summarized. Recommendations are given for cost-effective design of concrete domes over water and wastewater tanks.
