Original Design

-Lateral System:

Foundation system described, including figures, plans, elevations.

Original Design

-Advantages and Disadvantages:

Table listing advantages and disadvantages.

Design Code change

Conclusions

Design Code Change

-Original Design Code: BOCA 1996-Code for redesign: IBC 2000-Connecticut plans to adopt IBC 2003 in 2005 as the state’s governing code.-IBC 2000 used in lieu of IBC 2003 since it is currently more common.

Effects of Code Change: Wind

-BOCA 96 Basic Wind Speed: 90 mph-IBC 2000 Basic Wind Speed: 110 mph-Five second gust required by IBC 2000-Wind base shear increased by ~30%

-Include Pressure and shear profiles-

Effects of Code Change: Seismic

-Include shear tables-

-Describe code differences-
