SECTION 05521 - PIPE AND TUBE RAILINGS <br /> PART 1 - GENERAL <br /> 1 . 1 RELATED DOCUMENTS <br /> A. Drawings and general provisions of the Contract, including General and Supplementary Conditions and <br /> Division 1 Specification Sections, apply to this Section. <br /> 1 .2 SUMMARY <br /> A. Section Includes : <br /> 1 . Stainless-steel pipe and tube railings. <br /> 1 .3 PERFORMANCE REQUIREMENTS <br /> A. Delegated Design: Design railings, including comprehensive engineering analysis by a qualified <br /> professional engineer, using performance requirements and design criteria indicated. <br /> B . General : In engineering railings to withstand structural loads indicated, determine allowable design <br /> working stresses of railing materials based on the following : <br /> 1 . Stainless Steel : 60 percent of minimum yield strength. <br /> C . Structural Performance : Railings shall withstand the effects of gravity loads and the following loads and <br /> stresses within limits and under conditions indicated: <br /> 1 . Handrails and Top Rails of Guards : <br /> a. Uniform load of 501bf/ ft. (0. 73 kN/m) applied in any direction. <br /> b . Concentrated load of 200 lbf (0. 89 kN) applied in any direction. <br /> C , Uniform and concentrated loads need not be assumed to act concurrently. <br /> 2 . Infill of Guards : <br /> a. Concentrated load of 50 lbf (0.22 kN) applied horizontally on an area of 1 sq. ft. (0.093 <br /> sq. m) . <br /> b. Infill load and other loads need not be assumed to act concurrently. <br /> D . Thermal Movements : Allow for thermal movements from ambient and surface temperature changes <br /> acting on exterior metal fabrications by preventing buckling, opening of joints, overstressing of <br /> components, failure of connections, and other detrimental effects . <br /> 1 . Temperature Change : 120 deg F (67 deg C), ambient; 180 deg F ( 100 deg C), material surfaces. <br /> E . Control of Corrosion: Prevent galvanic action and other forms of corrosion by insulating metals and <br /> other materials from direct contact with incompatible materials . <br /> Wabasso Beach Park 05521 - 1 <br /> Indian River County <br /> DAA Project No . 6008 <br />
