5 INTRODUCTION Purlins and girts are complementary products to structural steel and used primarily in the walls and roof of a building. All purlins and girts are cold-formed using high-performance steel in order to minimize weight while maximizing capacity. As with all Canam Canada products, our purlins and girts meet strict quality standards. Canam Canada fabricates a complete range of C and Z sections for use as purlins and girts at its plant in Boucherville, Quebec. The nominal depth of these sections varies from 6 inches (152 mm) to 14 inches (356 mm). ADVANTAGES Our automated equipment eliminates waste by cutting sections to exact length, which results in substantial cost savings for our customers. We can also manufacture sections according to your shop drawings. Canam Canada can equally apply a coat of red or grey primer to cold-formed sections according to the specifications of CPMA Standard 1-73A. This service is offered at a competitive price. HIGH-PERFORMANCE STEEL All purlins and girts are cold-formed from high-strength steel in order to minimize weight while maximizing capacity. The steel used to fabricate such members complies with the requirements of ASTM Standard A1011 HSLAS Grade 50. DESIGN The capacity of all Canam Canada cold-formed C and Z sections complies with the requirements of the CAN/CSA- S136-M07 North American Specification for the Design of Cold Formed Steel Structural Members with a material grade of 345 MPa (50 ksi). TOLERANCES The fabrication tolerances of all Canam Canada coldformed C and Z sections comply with those specified in the ACNOR CAN/CSA-A660-M04 standard for the Certification of Manufacturers of Steel Building Systems. Material thickness tolerances comply with standard ACNOR CAN/CSA-S136-M07.

6 LATERAL STABILITY OF PURLINS THROUGH-FASTENED ROOF The use of a through-fastened roof does not preclude the need for proper purlin bracing. The roof structure can provide lateral stability but supplies no torsional stability whatsoever for Z or C sections. Discrete bracing should therefore be incorporated in the design phase in order to control torsional flexural buckling. DEFINITION OF DISCRETE BRACING A discrete brace can take a multitude of different forms as seen in the figures below. All of these types of bracing are discrete because the movement is controlled only at the particular brace point (Galambos 1998). The required bracing force and stiffness for this type of brace is dependant upon the number of braces provided STANDING SEAM ROOF The use of a standing seam roof does not preclude the need for adequate purlin bracing. The roof structure can only provide partial lateral stability and supplies no torsional stability whatsoever for Z or C sections. Discrete bracing should therefore be incorporated in the design phase in order to control torsional flexural buckling. EXAMPLES OF LATERAL STABILITY: TYPE 1 Symmetrical about the ridge Purlin brace Ridge brace TYPE 2 Symmetrical about the ridge Ridge channel Cope angles at top flange Angle cross brace at eaves Angle top and bottom (typical) Fasteners at each purlin (typical) Eave strut 7

7 LATERAL STABILITY OF PURLINS TYPE 3 Symmetrical about the ridge Steel deck Channel bracing Eave strut Ridge channel C section for discrete bracing Clip angle Purlin Structural bolts ANCHORAGE OF PURLIN BRACING (ANTI-ROLL SAFEGUARD) If no discrete bracing line is used, anchorage is required at each purlin support, which must be designed to resist in-plane forces. In certain instances, anti-roll clips may also be necessary. EXAMPLES: Purlin Anti-roll clip Structural fastener Purlin Shop weld Structural fastener Anti-roll stiffener Purlin Shop weld Anti-roll U section Structural fastener Horizontal plate Horizontal plate Structural bolts Structural bolts Structural bolts If one or more discrete bracing lines are used between purlin supports, the supports must be designed to resist in-plane forces as explained in the paragraph above. Substantial anchorage is required for the discrete bracing line at each eave and ridge end. The applied load on each line can be calculated according to standard S136. 8

9 LATERAL STABILITY OF PURLINS SAMPLE CALCULATIONS METRIC Snow load = 2.4 kpa Wind pressure = 0.6 kpa Dead load = 1 kpa 8,000 mm 7 spaces of 1,100 mm Ridge channel Z section Wind (uplift) = 1.2 kpa 12 2 Example: Single span of Lx = 6,000 mm with a 1,100 mm spacing between Z sections. There are 9 sections (7 spaces of 1,100 mm) per building slope with a roof pitch of in 250 mm (angle of a = 9.46 degrees). The sloped length of one side is 8,000 mm with 300 mm between the ridge and the last section. Loads: Dead load (dl) of 1.0 kpa Snow load (sl) = 2.4 kpa Gross wind load in pressure (wp) = 0.6 kpa and 1.2 kpa of wind uplift (wu) STEP 1: CALCULATION OF Z SECTION WN AND WT LOADS FOR EACH LOAD wn dl = dl cos (a) Spacing = 1.09 kn/m wn sl = sl [cos (a)] 2 Spacing = 2.57 kn/m wn wp = wp Spacing = 0.66 kn/m wn wu = wu Spacing = 1.32 kn/m } wn wt dl = dl sin (a) Spacing = 0.18 kn/m wt sl = sl [sin (a)] 2 Spacing = 0.07 kn/m } wt STEP 2: LOAD COMBINATIONS ACCORDING TO THE 2005 NATIONAL BUILDING CODE Gravity: the greater of: 1.25 wn dl wn sl wn wp = 5.48 kn/m control 1.25 wn dl wn sl wn wp = 3.57 kn/m total wn = 5.48 kn/m total wt = 0.33 kn/m Uplift: 0.90 wn dl 1.4 wn wu = 0.87 kn/m 10

10 LATERAL STABILITY OF PURLINS STEP 3: CALCULATION OF LOADS ACCORDING TO WT AND WN Single span: Mf x = total wn Lx 2 / 8 = kn m Mf y = total wt Lt 2 / 8 = 0.37 kn m Where: Lt is the maximum distance between supports where discrete bracings are found. Assumption: According to the Canam table, one row of local lateral restraints at regular intervals, therefore, Lt = 3,000 mm. Vf = total Wn Lx / 2 = kn Mf uplift = uplift Lx 2 / 8 = 3.92 kn m STEP 4: PRELIMINARY CHOICE OF A SECTION Choice: new nomenclature: 305Z76-326M; former nomenclature: Z305x14 Assumption: the roof deck only partially maintains the compression flange on the Z section with a standing seam roof. Connections every 610 mm c/c provide only partial lateral support. Calculation of the moment under gravity loads Value of the Canam table (Mu) for Lt = 3,000 mm = 26.5 kn m Mrx = Mu Mry = 0.9 Sy Fy = 6.77 kn m where Sy = 21.8 x 10 3 mm 3 and Fy = 345 MPa according to the Canam table Interaction equations Mfx / Mrx + Mfy / Mry = 0.99 <= 1 ACCEPTABLE Calculation of the moment under uplift loads Mr uplift = Value of the Canam table (Mu for Lt = 3,000 mm) = 26.5 kn m Note: local lateral restraints can be used for uplift. Mf uplift / Mr uplift = 0.15 <= 1 ACCEPTABLE Calculation of shear (worst case scenario is shear near the support) Vr = Value of the Canam table (Vr) = kn Vf / Vr = 0.18 <= 1 ACCEPTABLE Calculation of web crippling with 100 mm of bearing Pr = Value of the Canam table (Pr) = kn Pr reduced because of the pitch = Pr [sin (90 a)] 2 = kn Vf / Pr reduced = 0.68 <= 1 ACCEPTABLE Reinforcement between the bearing and the support in the section s web is therefore not required in this step. Calculation of deflection I min (deflection < span / 180) = 180 x 5 x (wn sl + wn wp) x Lx 3 / (384 x 200,000 MPa) = x 10 6 mm. The Ix inertia of section 305Z76-326M according to the catalog is 22 x 10 6 mm 4 greater than the minimum inertia. Section 305Z76-326M (Z305x14) is acceptable. 11

11 LATERAL STABILITY OF PURLINS STEP 5: DESIGN OF THE ROW OF BRACING MEMBERS AND THE RIDGE CONNECTION According to the information in table 1 on page 13, the factored vertical load of a 6,000 mm purlin with a 2/12 pitch and a bracing line is 0.367/section/1.0 kn/m. The axial load of 8 sloped sections with a factored vertical load of 5.48 kn/m is: x 8 purlins per slope x 5.48 kn/m = 16.1 kn factored/bracing line. The local lateral restraint must be sized from top to bottom to transfer this load. In our example, the pitch is 2/12, the lateral restraint could be an angle welded from top to bottom with a cross bridging weld every 3 spaces from top to bottom. Other types of lateral restraint can also be used (see the beginning of the present section). In our example, the 16.1 kn load will be offset by the component connecting the Z section on each side of the ridge. The sizing of this part must be designed to achieve 16.1 kn where the section will be attached. STEP 6: DESIGN OF SUPPORTS ACCORDING TO THE PN EFFORT The Pn effort per section in each top flange above the support is 2.01 kn, which is equivalent to (as indicated in table 1 on page 13) multiplied by 5.48 kn/m. The moment developed in the section is equal to Pn x height of the section = Mf support = 2.01 kn x 305 mm = kn mm. Mr support = 0.9 x (Sx) x Fy = 0.9 x [(width at the bearing) x (thickness of the section) 2 /4] x = kn mm Where: width at the bearing = height of the section in mm. Mf> Mr NOT ACCEPTABLE. According to Step 4, an anti-roll clip must be installed between the web and the support. Two options are possible at this stage: the use of either a stiffener or an angle of suitable thickness (see page 8 for examples of anti-roll stiffeners). If an angle is used, it must have a minimum thickness of 8 mm by 200 mm wide and 200 mm high, which is equivalent to Mr = 864 kn mm. The use of this option presumes that only the angle is connected to the support. The choice of a 75 mm long by 200 mm high by 3 mm thick bearing stiffener would allow for a 200 mm wide by 200 mm high by 3 mm thick angle, which is lighter. General notes: In the example above, the use of only one local lateral restraint slightly increases the weight of the Z section. However, the second discrete bracing line could have a greater impact. Consider the results with 2 rows: 2 discrete bracing lines with the same pitch: 254Z76-290M with a Pn = of the table x 8 x 5.48 kn/m = 7.3 kn/bracing line. Note that if no discrete bracing line had been used in this second example, it would not be considered acceptable even in the presence of several sag rod lines and with the largest available section. The choice of conventional steel deck instead of a standing seam roof is slightly conservative for a sloped roof when the tables in the present catalog are used. 12
