Arnold, Sean McAlpine, Vic Gilbertson, Les Formell <br /> A meeting was held.on 18 May 1995 tor review the condition of three of the existing Silver Lake Camp <br /> Buildings. The following Items were noted: <br /> 1. M Bar 0 Building: <br /> • A. The building appeared to have some structural concerns which were examined, which was <br /> indicated by some portions of the roof which were concave, as well as some bowed portions of the <br /> exterior wall: <br /> 1-The roof trusses In the main hall are constructed of 2 x 6 studs with a spacing that varies <br /> from 6 feet to 8 feet 4 Inches on center (see attached sketch of truss). This truss design <br /> was reviewed with a structural engineer(the Schuett-Meler Company),and their design was <br /> analyzed: ft Is the engineer's conclusion that the trusses are essentially 'self supporting' <br /> with a total load capacity of 10-15 pounds per square foot, far below the 40 pst currently <br /> required by code. The engineers speculated that the reason that the roof is still standing <br /> is that the sheathing on the Interior and exterior of the trusses is providing additional <br /> support. <br /> 2. The floor is supported by a series of jury rigged posts which have no lateral bracing.The <br /> lack of lateral bracing means that under heavy load conditions, the deflection of the floor <br /> could cause the supports to `tip° or slide out, which could result in fallure of the floor <br /> structure. <br /> S. Conclusions; - <br /> Neither the floor or roof structure appear to comply with current code requirements. That the - <br /> structure has not collapsed Is a combined function of luck and the sheathing holding things up it <br /> could also continue to hold up, but In the Interest of public safety Its continued use cannot be <br /> reccommended,especially not when the floor could be heavily loaded Qarge groups)orwhen there <br /> Is any superimposed load (snow) on the roof. <br /> • yti trsoh yxe-Xir*►Q . 5+�� . �j Ti'tnx 6T/- eA 1�1 ��n� 64�' <br /> P 11, � <br /> Q � orC cvn�t,C'SaTio� , <br /> 1 S�� <br />
