Post a Comment. Excel Sheets. Design of C Purlins Spreadsheet. October 01, The alternative approaches to design were reviewed and a semi-empirical design procedure was described which resulted in safe but competitive load-span tables. This paper describes the design of Multibeam Mark 3. This involves a further evolution of the cross-section together with further improvement of the design procedure. The tendency is to continue to move away from reliance on testing and towards an approach which is much more orientated towards design by calculation, a trend which is becoming increasingly necessary in view of the proliferation of different cladding types, all offering different degrees of restraint to the purlin.

Description This spreadsheet is to be used to check the adequacy of roof purlins for a specified combination of loads. This spread sheet can only be used for load combinations with two variables. In most cases the worst case scenario is 0. Only the values in the highlighted cells need to be changed. Submitted By:. Jahleel Valermos. This download is for Registered Users Only.

By the way, in structural reports, is it more desirable to have all working shown or will results in tabulated format with code cited in the reference column be adequate. My aim is to develop spreadsheets that only need to have the input changed and then printed out. JohnDoyle[Admin] 8 years ago. Thanks for your second contribution.

Design of C Purlins Excel Sheet
Roof purlin needs no introduction to anyone in the construction industry. They are members used to directly support roof sheeting materials, and could be made of timber or steel. In timber construction, purlins are nailed to the rafter or supporting trusses, while in steel roof construction, they are welded or bolted to the rafters or trusses by the means of cleats. In their design life, purlins are subjected to dead load e. This post will be focusing on design of steel purlin using cold formed sections. Arrangement of Purlins By default, purlin sections assume the slope of the roof they are supporting. The spacing of purlins usually call for careful arrangement, in the sense that it should follow the nodal pattern of the supporting trusses. What I mean in this regard is that purlins should be placed at the nodes of trusses and not on the members themselves so as not to induce secondary bending and shear forces in the members of the truss. Furthermore, if manual analysis is employed to analyse a truss loaded in such manner, such secondary stresses cannot be captured since we normally assume pinned connections. Cold formed Z Zed and C channel sections are normally specified for purlins in steel structures see their form in image below. As compared with thicker hot rolled shapes, they normally offer the advantages of lightness, high strength and stiffness, easy fabrication and installations, easy packaging and transportation etc. The connection of purlins can be sleeved or butted depending on the construction method adopted. The choice of the arrangement to be adopted can depend on the supply length of the sections as readily available in the market, the need to avoid wasteful offcuts, the loading and span of the roof, the arrangement of the rafters etc. Therefore the roof designer must plan from start to finish. However, single and double span butt joint system are the most popular in Nigeria, due to their simplicity, and the culture of adopting shorter roof spans in the country. However, they are less structurally efficient than sleeved connections. Design Example We are to provide a suitable cold formed channel section for the purlin of the roof arrangement shown below. Section Properties In the design of purlins using ENwe normally utilise the effective section properties. However, I am going to make a sample calculation for the section that we are considering. Effective section properties of the flange and lip in compression clause 3. Effective Width of the edge fold lip Clause 3. We now have to use the initial effective cross-section of the stiffener to determine the reduction factor, allowing for the effects of the continuous spring restraint. The elastic critical buckling stress for the edge stiffener is.
