Design of Anchor Reinforcement in Concrete Pedestals

In petrochemical industry concrete pedestals commonly support static equipment ie horizontal vessels and heat exchangers and pipe-rack or compressor building columns In order to fully-develop the strength of anchor in un-reinforced concrete the Appendix D of the ACI 318-05 requires the use of significantly large concrete pedestals/octagons...
