Description There is no floor in this structure, only gravel. The foundation wall is about 1 foot high and is collapsing. Structural and Fire - The open end of the shed is subject to collapse due to seismic or wind forces. The building is racked and the interior walls have been recently cross-braced to prevent further racking. This building has no fire resistive coverings such as gypsum wallboard, which increases the probability of the building catching fire. Remedial Safety Measures - Shoring the Shed 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. Electricity would need to be disconnected and sprinklers installed to reduce the fire hazard. A wall would need to be constructed at the open end of the structure to prevent anyone from entering the structure and for seismic reinforcement. Some repairs to the cut trusses would be required. Garage or Shop Space Retrofit - Garage or shop space retrofit requires the installation of shear walls and holdowns. If the open end is to remain open, pre-manufactured narrow shear walls would be required. 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). Windows and doors can remain in place since the proper 2 to 1 aspect ratio for the shear walls already exists. Studs would be added in some areas and headers over the doors and windows. The walls would be covered with fire resistive gypsum wallboard. All existing wiring would be removed and replaced with new wiring. A sprinkler system would be installed. New roof trusses would be added to strengthen the roof against the 30 psf snow load and to replace the cut trusses. 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. A concrete floor would be added to give stability to the new foundation. final Report \9 April \6, 2002
