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 & structural steelwork design safely design structures incorporating. Design Codes is a modular system primarily for use in temporary works and as such complies with the following codes:- BS 449:1969 inc Amendment - Specification for the use of Structural Steel in Buildings BS 5975: Code of Practice for Temporary Works Procedures and the Permissible Stress Design of Falsework In addition, it was recognised during the development of that, with regard material specifications in particular, the more onerous requirements of the following two codes should be adopted. BS 5400: Part 3: Code of Practice for the Design of Steel Bridges BS 5950: Part 1:2000 and Part 5: Structural use of Steelwork in Buildings In the production of this manual, analysis has been carried out the latest revisions of these codes. Eurocodes The equipment is currently being assessed Eurocodes. Strengths relating these codes will be published in a future revision this document. Please refer Mabey Hire engineering team for the latest information. Safe Working Loads The safe working loads for members & joints given in the Technical Data Sheet are generally based on theoretical values calculated in accordance with BS 449 & BS 5975 but with additional safety facrs applied ensure a minimum facr of safety of 2.0. In many cases full scale laborary tests have been carried out & compared the calculated values. In all cases a minimum facr of safety of 2.0 against the onset of permanent deformation has been established. All loads are all given as characteristic allowable working loads / strengths i.e. unfacred. In addition, the stated capacities maintain the facrs of safety imposed by BS 5400 & BS Product Use For the handling and use of, please refer the Product Information & Use Sheet Ref. PIUM25.
