Description Historical Site Analysis Structural and Fire - There is no fire resistive interior wall covering such as gypsum wallboard or plaster. The office has thin plywood sheets for the walls and ceiling. Cellulosic fiberboard over studs offer little shear resistance to wind or seismic forces (about 125 pounds per linear foot). Wiring is exposed in the north portion which poses a potential fire hazard. The doors are difficult to open and close due to the racking of the structure. Remedial Safety Measures - Shoring the Shower House against collapse due to natural forces (i.e., seismic, wind, snow, and fire) would require the installation of shear walls and holdowns and bracing of the roof every 25 square feet. Bracing of the roof can be eliminated if the building is locked and is only entered when snow is off the roof and proper warning shall be posted at the doors. Shear walls would be anchored into new concrete foundation walls with proper footings which can be done with shoring and jacking procedures. Some windows and doors would need to be removed to maintain proper 2 to 1 aspect ratio for the shear walls. Electricity would need to be disconnected and sprinklers installed to reduce the fire hazard. Office Space Retrofit - Office space retrofit requires the installation of shear walls and holdowns. Shear walls would be anchored into new concrete foundation walls with proper footings which can be done with shoring and jacking procedures. In this case, siding would be removed and replaced so that the cellulosic fiberboard can be switched out for plywood or OSB board which has a higher shear resistance (up to 350 pounds per linear foot). Some windows and doors would need to be removed to maintain proper 2 to 1 aspect ratio for the shear walls. Studs would be added in some areas and headers over the doors. The walls would be insulated and covered with fire resistive gypsum wallboard (the existing coverings would be removed since they are combustible). All existing wiring would be removed and replaced with new wiring. A sprinkler system would be installed. Extra roof trusses would be added to strengthen the roof against the 30 psf snow load and the attic spaced filled with insulation. Vents would be added at the ridge and the soffit areas to provide the required 1/300 roof ventilation. Windows would be repaired as required and replaced where tempered glass is required. The concrete floor would be removed and replaced and flooring materials (either carpet or vinyl flooring) placed. The current wood floor diaphragm would need upgrading. A new heating system would be installed. Final Report \7 April \6, 2002
