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 />
