Opinions on which code to use: IBC 2003 (adopted by SC May 2004) governed the project which specified the use of ACI 530-02 (“Adopted as ACI Standard” Feb 2002). However, a newer version of ACI 530 was issued shortly after the IBC 2003 was adopted by the state. Should have ACI 530-05...
I typically specify a lesser-required compressive strength, but need the higher compressive strength on this project to accommodate the flexural strength & bending imposed by the roof trusses (high lateral loads due to hurricane force winds & seismic activity). Due to the higher strength...
ACI 530.1-05 (Specification for Masonry Structures) Table 2 (Compressive strength of masonry based on the compressive strength of concrete masonry units and type of mortar used in construction) specifies the “net area compressive strength of CONCRETE MASONRY UNITS” and the “net area compressive...
