A few times each year I get asked to design modifications to a bldg, usually light frame walls with wood structural panels, that has a existing CMU foundation stem wall or bsmt wall that is unreinforced & ungrouted. Most of the time there is no bond beam at the top of the wall and no anchor...
After one has used the subject code to calc. the base shear for Wind & Seismic loads and determines that Wind will govern the design how should one "operationalize" the instructions in Chapter 11.1.1 (p.109) and Appendix C11.1.1 (p.353)?
Appendix "C11.1.1 Purpose" sez that even though the Wind...

2. When designing reinf. concrete retaining walls for a seismic load, E, in addition to the lateral soil loads does the E get a load factor? Since E comes from ASCE 7-05 and is a Strength level load it seems to be overkill to tack on...
