3 1.0 Introduction Application This Technical Data Sheet is designed provide information of sufficient content and detail as enable engineers, competent in structural analysis and structural steelwork design, safely design structures incorporating. Design Standards The resistance values given in this data sheet have been calculated in accordance with the latest revisions of the following Eurocode Standards: BS EN :2005 incl. corrigenda Feb 2006 and April 2009 BS EN :2006 incl. corrigendum Nov 2009 BS EN :2006 incl. corrigendum April 2009 BS EN :2005 incl. corrigenda Dec 2005, Sept 2006, July 2009 and Aug 2010 Design Philosophy The British Standard method of permissible stress design has been replaced by the Eurocode limit state design method, which utilises a partial facr method. The principles of the Eurocode design method are outlined below. The design value of an action effect shall not exceed the corresponding design resistance of the element: F d R d Where: F d = Ɣ F x F k R d = R k / Ɣ M F d is the design value of an action (be that a force, moment, or shear etc.) F k is the characteristic value of an action (such as dead load, live load etc.) R d is the design value of the resistance (be that a force, moment, or shear etc.) R k is the characteristic value of the resistance (e.g. axial capacity) Ɣ F is the partial facr for actions Ɣ M is the partial facr for a material property This data sheet gives Safe Working Capacities by assuming a Ɣ F value of Ɣ M is used in accordance with the Eurocodes. Please refer further details on the following page. Document Ref: TDSM10 Page No. 3 of 14

4 1.0 Introduction How this Eurocode Data has been Established This data sheet gives Safe Working Capacities that may be compared actual loads/effects. Mabey Hire have chosen not publish Design Resistance values because they could lead errors and unsafe designs due :- Values being mistaken for SWL values (major risk) The risk of low Partial Facrs being used in certain circumstances resulting in overall Facr of Safety (FOS) values of < 1.40, inappropriate for Temporary Works The Characteristic Resistances of all the products have been assessed in detail in accordance with the Eurocodes. Where the values have been influenced by the results of testing, the use of the test data has also been carried out in accordance with the requirements of the Eurocodes. Diagram Illustrating Facrs R k Ɣ M x (Ɣ F = 1.50) Mabey Strength Min FoS = 2.0 Safe working capacities in this data sheet are the lesser of these two values. How Use the Technical Data Sheet a) Use SWL values straight from the data sheet. In cases where the Eurocodes specify Ɣ F > 1.50 (e.g. certain rail and wind actions) then method (b) below should be adopted. Or b) Providing that Actions (Loads) have been multiplied by Ɣ F (Load Facrs) produce Design Load Effects, then tabulated values may be multiplied by 1.50 give minimum Design Resistances and compared the Design Load Effect. Minimum FOS When using method (b), Mabey Hire imposes a minimum Ɣ F x Ɣ M of This is eliminate lower FOS values that would be inappropriate for Temporary Works. We recommend that you contact Mabey Hire engineers for guidance. Document Ref: TDSM10 Page No. 4 of 14

5 2.1 Prop Units Details The Prop unit forms the basis of the System. Props are fabricated from twin 3mm thick cold-formed channel sections (Material Grade: S420 MC) and are provided with 14mm diameter holes in flanges & end plates allow connection of Bracing and Auxiliary Components using M12 bolts.

If applied via a local offset inducing concentrated loading then consideration should be given local failure, see Note NB 2: For horizontal prop applications, self-weight, debris and accidental loading effects should be taken in consideration. Note on Combined Effects Where appropriate the combined effects of axial load, bending & local effects must be considered. Please refer Mabey Hire Engineers where advice is required.
