Seismic Analysis and Design Review of a Power Plant Chimney

A 460 ft. tall reinforced concrete chimney for a power plant was designed under strict loading parameters including the effects of seismic forces. CA was asked to review the design of the chimney to assure it had been designed for the appropriate loads including seismic, wind, and dead loads. CA performed a finite element analysis of the chimney to determine the in-service stresses experienced by the chimney for various load combinations. Furthermore, CA reviewed the original and as-built plans and drawings, original design calculations, and analyzed the design procedure. CA determined the appropriate design procedure and loading conditions and assessed the addition of structural fiber reinforced polymer reinforcement to the as-built structure to provide supplemental stability and capacity.
