For the design of tilt-up walls with small axial gravity loads and large lateral forces, I suggest you use the "Alternate Design Slender Walls" method under 1997 UBC Section 1914.8. This code section was developed pursuant to research by a Joint Task Committee of the SEAOSC and Southern California Chapter ACI between 1979 to 1982. The Code language was developed by the SEAOC Building Code Committee between 1984 to 1987. The P-delta effect has been incorporated in the development of formaulae (14-4) and (14-5). The effective steel area, A(se), is based on membered subject to combined bending and axial load. You may find the development under the commentary of ACI Design Handbook Publication SP-17(97) page 432. If you are interested in the original version of the Committee recommendations, you may wish to contact the office of SEAOSC for the two publications - the "Yellow Book" on Tilt Up Walls; and the "Green Book" on the Research Report. I believe a spread sheet can easily be developed for design use. Warnings, please note that the "Green Book" was never updated by the Task committee and had several typo errors in the examples at the end of the publication.
