7 ZETA SLEEVED PURLINS This system utilises single bay purlin lengths joined with onneting sleeves at alternate supports. All purlins must be sleeved aross the penultimate support (see pages 4 and 5 or joint arrangement diagram). This system is onsidered to be the most eiient on the majority o buildings or bay entres up to 7.5m approx. The use o single span purlin lengths ensures easier on site handling and ompliane with Health & Saety Exeutive requirements. ZETA HEAVY END BAY PURLINS This is a ully ontinuous system with sleeves provided at all supports. The end bay purlins and sleeves to the penultimate support are inreased in gauge to ompensate or the lak o ontinuity aross the gable, hene the name (see pages 4 and 5 or joint arrangement diagram). This system is usually more advantageous or longer spans and/or heavier loadings where there are a minimum o six bays. Providing sleeves at all supports inreases the apaity by over % ompared to the equivalent sleeved system, with sleeves at alternate joints. ZETA DOUBLE SPAN PURLINS This system has been developed to utilise a minimum number o omponents leading to maximum speed o eretion on site. The purlins are ontinuous over two bays with simple onnetions at eah support. Joints are staggered with a minimum number o sleeves being required aross the penultimate support o alternate purlin lines to maintain ontinuity (see pages 4 and 5 or joint arrangement diagram). The double span system does not quite ahieve the same strength apaity as the equivalent sleeved system, but requires ewer omponents.

41 CANTILEVERS/SHALLOW PITCHED ROOFS CANTILEVER PURLINS It is sometimes neessary to extend purlins and ladding rails beyond the gable rame reating a antilever ondition. In this situation, the ollowing points should be onsidered: 1. The setions orming the antilever must be ontinuous aross the gable rame. The stiness o the antilever is improved i ontinuity is also provided aross the penultimate support (eg by providing a sleeve). 2. The antilever ends o the setions must be braed to prevent lateral displaement. The Ayrshire strut setion indiated on pages 13, 21 or 29 an be provided as a tie member. Alternatively, where the antilevered setions are to be lad, the inlusion o leader members to support the asia ladding should be suiient. 3. For steep slopes i.e. θ > 20 or Zeta, θ > 30 or Zeta II and Zed, diagonal members should be loated at the top o the slope (or at the base or ladding rails) to prevent displaement. 4. Cantilevers are generally deletion rather than strength ritial. We suggest that deletion o the antilever is heked or the worst relevent load ombination beore onirming its strength apaity. For urther advie and onirmation o suitable sizes or a given ondition, please onsult our Tehnial Servies Department. STRUT LOCATION FOR ALL ZETA II AND ZED SECTIONS (strut type VS1) Struts ixed in bottom holes Diagonal brae setion or steep roo slopes (see note above). SHALLOW PITCHED ROOFS (θ < 3 ) Alternate lines reversed with strut type braing between as required. Note: or all Zeta II and Zed setions provide Type VS1 struts.

Type VS2 shown or Zeta 200 (use VS1 or Zeta range). In this situation it is neessary to avoid a potential build-up o lateral ore in any one diretion due to the inlination o the priniple axes o the purlins. This an be ahieved by reversing alternate lines o setion to ae eah other. When sag bars are required in aordane with the tables on pages 9, 17, or we reommend that pairs o setions are braed together at the appropriate positions (i.e. mid-span or third points) using a standard Ayrshire strut setion, VS1 or VS2.

42 MONOPITCH ROOFS CONSTRUCTION DETAILS MONOPITCH ROOFS Where sag bars are required or a onventional duo-pithed roo, in aordane with the tables on pages 9, 17 or they will also be required or a monopithed roo. It is suggested that strut and diagonal braing setions are provided between the top two purlins at the higher eaves. This ats as a substitute or the apex tie member in a onventional duo-pithed roo and ties the purlin system bak to the steelwork. Sag bars an be provided in the required manner below these top two purlins. An alternative solution is to provide an eaves tie member at the high eaves position, ixed bak to a suitable strutural member apable o arrying the downslope ores rom the purlins. It should be noted that where sag bars are not required in aordane with the tables on pages 9, 17 or (i.e. Zeta purlins in the majority o appliations), no sag bars are required to the equivalent monopithed roo.

43 TILED ROOFS Struts and diagonal braes loated in top set o web holes. Due to magnitude o ores involved, we suggest that the diagonal braes are ixed diret to the steelwork. TILED ROOFS The use o old rolled steel purlin systems to support traditional tiled roo onstrutions has beome inreasingly popular over reent years. The ollowing oers design and installation advie with regard to the purlins in this situation. Unlike a onventional srew i xed steel ladding system, a built up tiled roo onstrution is not deemed to at as a diaphragm panel. Consequently, the purlin setions must be designed or a bi-axial bending ondition, taking into aount the downslope ores. The timber raters i xed to the top l ange o the purlins are still onsidered to provide ull lateral restraint to that l ange in ompression. Struts are provided to at as supports to the downslope ores as appropriate, with diagonal braes to transer these ores bak to the supporting steelwork. It should be noted that ties aross the apex are not required in this situation, assuming the timber raters are onneted at the ridge point. The number o struts and diagonal braings required is a untion o the geometry and loading onditions in eah individual ase, and advie should be sought rom our Tehnial Servies Department. Alternatively, Ayrshire s AyrSuite Plus 4 sotware provides an aurate and eonomi design tool that is available on request. CONSTRUCTION DETAIL AILS CLEATS Due to the inrease in Dead loads or a tiled roo onstrution, oupled with a steeper roo slope, a hek on the suitability o Ayrshire s standard leats (shown on pages 10, 18 or 26) must be made, and a stiener plate provided where appropriate. Partiular are must be taken where the diagonal braes are seured bak to the steelwork. Due to the magnitude o ore involved, it is suggested that these are i xed diretly to the steelwork l ange.

L Where ladding is deemed not to provide lateral restraint, speial restraining setions, termed Restraint Struts, are available to at as minor axis supports against lateral bukling as appropriate. For shallow pithed roo appliations ( < 3 ), two sets o diametrially opposed diagonal braings should be provided, as a minimum, to transer the restraint ores bak to the supporting struture. For steeper slopes, one set at eaves level should be provided as a minimum. The total number o diagonal braings required, in one or both diretions, is a untion o the roo slope length. Subjet to the type o lip ix ladding used, and the lip sizes, a seond ledger angle may be required to inrease the bearing width. Ledger angle to support weight o ladding by others.

48 HORIZONTAL CLADDING CONSTRUCTION DETAILS SUPPORT SYSTEMS FOR HORIZONTAL CLADDING Horizontally i xed ladding provides the Engineer/Arhitet greater versatility in the use o proiled sheeting. Ayrshire Metal Produts oer a number o solutions that provide simple, versatile and ost eetive support methods or this type o ladding system. Option 1. Vertial & Horizontal Grillage The most requently employed detail involves the use o vertial rails i xed between onventional horizontal rails as illustrated in Figure 1. Vertial Rails an be seleted rom the standard Zed or CW range using the Single Span Butted load tables. For systems where a double bearing width or speial apping detail is required at ladding joint positions the introdution o a Panel Joint Rail (PJR) is required. In this arrangement the vertial rails at as struts and a diagonal brae system is required or the horizontal rails, (see Figure 2. Braing Arrangement on opposite page). In this situation the horizontal rails must be designed as laterally unrestrained between the leat and vertial rail positions. Our AyrSuite Plus 4 integrated sotware suite (CD available on request), may be used or this purpose. Standard Cleats Ayrshire have developed a range o standard leats to allow a hoie o vertial rail to be inorporated into the support system. A ost eetive solution an be ahieved using pairs o HC style galvanised inset leats. (see Table 1. Cleat Seletor). For standard horizontal rail alignment (i.e. unsheeted l ange points up), use leats with B suix, (e.g. HC2B) at the bottom o the vertial rail and leats with T suix, (e.g. HC2T) at the top end.

50 HORIZONTAL CLADDING CONSTRUCTION DETAILS Option 2: Strutural Top Hat Solution A similar solution to the vertial rail/pjr arrangement but using ewer omponents and i xings. The use o a Top Hat setion spanning between the onventional horizontal rails, and i xed to the outer l ange removes the need or HC leats and redues the number o bolt i xings required by up to 20%. A separate braing support system (Restraint Struts and Diagonal Braing) is required or the horizontal rails to aord restraint and maintain alignment during onstrution. A Panel Joint Top Hat is also available or ladding joint positions. The Top Hat proile an be onneted to the ull range o Ayrshire setions, primarily Zeta, Zeta II, Zed and CW ranges. It should be noted that the horizontal rails in this situation are not restrained by the ladding system, and a separate restraining system in the orm o restraint struts is required. Please onsult our Tehnial Servies Department or advie. Alternatively, our AyrSuite Plus 4 integrated sotware suite may may be used to design laterally unrestrained setions. This program is available on request. 50 Slotted holes are available in the vertial Top Hat setions, and horizontally in the l ange o the rails. This provides vertial and horizontal adjustment on site to aid alignment. STRUCTURAL TOP HAT SOLUTION Double width Top Hat at panel joint positions, (re. THPJ ). Top Hat setions ixed to the langes o the horizontal rails. No leats required. Standard Ayrshire purlin/rail leats may be used to ix the horizontal rails to the stanhions. Restraint Strut and Diagonal Brae system required to restrain the horizontal rails as appropriate.

51 HORIZONTAL CLADDING Option 3: Vertial spanning rails Vertial spanning rails may be designed to span between a strutural top and bottom member, and aross any intermediate members as appropriate. In this solution, ties between pairs o setions should be provided to prevent lateral displaement under loading. Option 4: Mini-zed spaers in the avity o a built-up ladding system I a built-up ladding system is employed, the liner panel an be ixed vertially in the onventional way, with mini-zed spaers spanning vertially between rails. The horizontal outer sheet an then be ixed to these spaer bars. This solution assumes that the vertial liner is aesthetially aeptable, and the mini-zed spaer bar is struturally apable o spanning between the horizontal rails. It should be noted that, in this situation, the horizontal rails are restrained laterally and the published load tables in our Purlin Design Manual are appliable. Strutural support beams at top and bottom. C STANCHION C STANCHION Vertial spanning rails with alternate lines reversed. Struts between pairs o rails as appropriate (i.e. at L/2 or L/3 points subjet to span). CONSTRUCTION TRUCTION DETAIL AILS 51
