Chapter 12 dictates which lateral force-resisting systems are permissible for a given Seismic Design Category. It provides height limits for different systems. For example, an "Ordinary Masonry Shear Wall" may be unlimited in height in Seismic Design Category A but prohibited in Seismic Design Category D.
The total lateral force at the base of the structure, known as the Base Shear ( asce 7-05 seismic pdf
Therefore, if you are working on a building permitted under the 2006 or 2009 International Building Code (IBC), your structural calculations must reference ASCE 7-05. You cannot use ASCE 7-10 or 7-22 for a permit issued in 2008 unless you do a full code upgrade (which is rarely cost-effective). The total lateral force at the base of
The ASCE 7-05 standard was published in 2005 and provides minimum design loads for buildings and other structures. The seismic design provisions outlined in this standard are crucial for ensuring that structures can resist earthquake forces and minimize damage during seismic events. The standard provides a framework for engineers to design and analyze structures to withstand seismic loads, which are critical for ensuring the safety of building occupants and the structural integrity of the building. The seismic design provisions outlined in this standard

ASCE 7-05 is obsolete for new construction (in most US jurisdictions), but it is the bible for existing structures built roughly between 2006 and 2010.
