Abstract:
The commentary on Appendix A has been approved for publication as part of the Supplement to ACI 349-76, Appendix A on thermal considerations was published in the February 1977 ACI JOURNAL, and, following approval, was incorporated in the 1977 Supplement to ACI 349-76. Appendix A presents minimum requirements for members subjected to time dependent and position dependent temperature variations occurring during normal operation and accident conditions. The commentary presents some of the considerations of the committee in developing the code requirement published in Appendix A. Appendix B defines minimum requirements for design of steel embedments used to transmit loads from attachments into the reinforced concrete structures governed by the code. Loads may be transmitted into the structure by means of tension, bearing, shear, friction, or any combination thereof. The design limits have been established using both analytical and test methods.
