A. INTRODUCTION <br />The purpose of this Report is to determine the structural adequacy of the 65 ft. x45 ft. aluminum outdoor stage roof top structure (with sound wings) fabricated byTotal Structures, Inc. for Pacific West Investments. In addition, overturning anduplift stability of the roof top structure due to various gravity and wind loadcombinations will be investigated. <br />The roof top and sound wing structure will be modeled using the Finite ElementMethod (FEM) based on geometry and material property information provided byTotal Structures, Inc. The description of our FEM model was determined from; (1)fabrication shop drawings of the aluminum components and (2) section andmaterial properties per telephone conversations with Mr. lan Coles of TotalStructures, Inc. <br />The design gravity loadings used in our analysis are consistent with the maximumanticipated loadings to be applied to the roof top structure as provided by TotalStructures, Inc. to Pacific West Investments. The design wind loadings used inour analysis are consistent with ANSI/ASCE 7-95 wind loadings for a 3-secondgust wind speed of 70 mph, which is consistent with sound engineering practice, for a temporary structure located in the western portion of the United States. Dueto the lightweight and flexible nature of the roof top structure, lateral seismicforces need not be considered. <br />The niaximum member stresses resulting from our analysis will be compared withallowable stresses as defined by the Aluminum Association in "Specifications forAluminum Structures," Fifth Edition. The. maximum bolt stresses resulting fromour analysis will be compared with allowable stresses as defined by the AmericanInstitute of Steel Construction (AISC) Code, Ninth Edition.Based on theconclusions of our analysis, recommendations are offered to assure that the rooftop structure will performadequately for its intended usage. <br />1 <br />1
