The purpose of PCI MNL-140-12 is to assist in the design of precast concrete structures using the seismic design provisions of the 2006 edition of the IBC. The seismic design provisions of the IBC are discussed in detail and are illustrated in this publication with examples of typical building and parking structures located in regions of low, moderate, and high seismic hazard and founded on different types of soil. In the examples, structural members are designed and detailed according to Chapter 19 of the IBC, which is based primarily on ACI 318-05 with a few modifications as well as ASCE 7-05.
