MCMEL Aluminium productsDesign manual for railing systemsDesign Manual forM.C.M.E.L Railing SystemFORDESIGNERS, ENGINEERS, ARCHITECTS,CONTRACTORS & INSTALLERS.www.mcmel.ca1 - USES OF RAILINGSM.C.M.E.L. railing systems are used in homes and inresidential, commercial, and industrial buildings toensure safety on balconies, staircases, mezzanines orall structure over 2 steps.M.C.M.E.L. railing systems consist specifically ofvertical aluminum component parts, posts, whichsupport horizontal and vertical loads. Loads aretransferred to various floors by means of anchoragesor screws. The handrails are the horizontalcomponents connecting the posts that transfer thestatic and dynamic loads (horizontal and vertical) tothem.The spindles are the components that fill the necessaryspace for railing systems. They can be horizontal,vertical, or a combination of both. In M.C.M.E.L.system, these components can be constructed fromdifferent materials such as aluminum, glass panels orhybrid combination.Prepared and approved by:Patrice Austin, ing.Digitech 3D inc.FIGURE 1: THE COMPONENT PARTS OF A RAILINGPrepared by Patrice Austin, eng., Digitech 3D inc. – DI003-001-CON-0001-H1

MCMEL Aluminium productsDesign manual for railing systems5.2 LOAD COMBINATIONIn cases where the only load is the surcharge due tousage, the Ontario Building Code 2012 defines loadcombination as follows:6 - STRUCTURAL ANALYSESThe load distribution and the structural analysis of thedifferent railing systems are determined in accordancewith the following parameters:Resistance calculation to the ultimate limitstates: 1.5 LDeflection calculation to the serviceability limitstate: 1.0 L For the glass panel included railing, the followingcombinations are considered: 1. Resistance calculation to the ultimate limitstates: max (1.5L, 1.4W)2. Deflection calculation to the serviceability limitstate: max (L, W)L: surcharge, according to the Ontario Building Code2012W: wind load, according to the Ontario Building Code2012It should be noted that the code doesn’t require thecombination of wind loads and surchargessimultaneously.www.mcmel.ca The railing system geometry such as heightand post spacing;Different types of railing system componentssuch as handrails, posts, handrail base, low railand bars;The limit conditions: the type of connection andattachment at the railing system ends as wellas the anchorage stiffness of the posts in theground.The handrail’s continuity, handrail, and postrelative stiffness, the type of spindle, itsspacing, etc.Structural design and verification has been performedaccording CAN/CSA-S157-05/S157.1-05 (R2010) Strength Design in Aluminum, CAN/CSA-A23.3-F04(C2010) – Design of Concrete Structures, CAN/CGSB12.20-M89 Structural Design of Glass for Buildings.According to the Ontario Building Code 2012, thestructural analysis is carried out by the SolidWorkssoftware, a linear analysis to the limit states (SeeFigure 6 for an example of our analysis).Design tables, 4 and 5, are prepared based on theanalysis results considering different posts, thefactored load or real load if guard has been tested, andthe spacing between posts. These calculation tableswere established for a 1.06 m (42 in) railing height.For a different height, the designer should do a morein-depth analysis.According to the 4.1.5.14.2 sentence of OntarioBuilding Code 2012, a 0.5 kN load is horizontallyapplied on the spindles or on the glass railing and it isexerted on 100 x 100mm square. According to ouranalysis, all M.C.M.E.L railing systems can resist anapplied load and it is not necessary for any verificationby the designer in order to fulfill this code requirement.Prepared by Patrice Austin, eng., Digitech 3D inc. – DI003-001-CON-0001-H8

Subject to thequalifications of Paragraphs 6) and 7), staircasehandrails and railings must have a height:i. of at least 865 mm; andii. of at most 965 mm.4) It is not mandatory for handrails installed in additionto the minimum required handrails to conform toParagraph 5).5) When railings are required, landing handrails mustnot be higher than 1,070 mm.6) Except when it is interrupted by change-of-directionrailings or by door openings, at least one handrailmust continue for the entire length of the staircaseor ramp, including landings (see Appendix A).www.mcmel.ca7) Handrails must finish in a way that does not impedethe passing of pedestrians or constitute a risk (seenote A-3.4.6.5 8).8) Staircases and ramps must have at least one sidehandrail that extends horizontally for at least 300mm at each end (see note A-3.4.6.5. 8).9) The clearance between handrails and all surfaceslocated behind them must be:a) at least 50 mm; orb) 60 mm if the surface located behind the handrailsis rough of abrasive.10) Handrails and their supports must be calculatedand built to resist the highest of the following loads:a) a concentrated load of at least 0.9 kN appliedat any given point and in any given direction,for all handrails; orb) a uniform load of at least 0.7 kN/m applied inany given direction, for handrails that are notlocated inside a building.11) It is necessary to install handrails on both sides ofa ramp.3.4.6.6. RAILINGS1) All emergency exits must be protected on each sideby a wall or a firmly attached railing.2) Subject to the qualifications in Paragraph 4), railingsfor emergency exit stairways must be of a height ofat least 920 mm measured perpendicularly from thenosing of the step to the top of the railing, and of atleast 1,070 mm to the periphery of the landings.3) Railings for emergency exit ramps and theirlandings must be of a height of at least 1,070 mmmeasured perpendicularly from the surface of theramp to the top of the railing.4) Railings for outdoor staircases and landings of morethan 10 m above the adjacent ground must be of aheight of at least 1,500 mm measuredperpendicularly from the surface of the landing orthe nosing of the step to the top of the railing.5) The openwork sections of the railing of anemergency exit must not allow the passage of aspherical object of more than 100 mm in diameter,unless it can be demonstrated that openworksections with dimensions greater than this limit donot present a risk.6) Stairwell windows with a support of at least 900 mmhigh in relation to the nosing of the step or a heightof at least 1,070 mm in relation to a landing must:a) be protected by a railing whose upper part islocated:Prepared by Patrice Austin, eng., Digitech 3D inc. – DI003-001-CON-0001-H24
