RC Pier says it has been updated for AASHTO LRFD 8th Edition. However, based on the Theory it appears that the pier cap for a multi-column pier is still designed using a frame analysis and beam theory (B-region) for all sections. With the new code, does RC Pier design the pier using the D-region criteria of Section 5.8.2? If not, will an update be provided in the near future which will allow Strut-Tie-Model (STM) to be used in the design of the pier cap and the footings per Section 5.8.2 for D-regions.
