Multideck 80-V2 Multideck 80-V2 is designed to incorporate all the advantages of the Multideck 60-V2 but in a deeper profile to provide longer spans up to 5.4m unpropped. • Concrete Volume Savings Due to its unique profile Multideck 80-V2 requires less concrete than other decks to achieve any given slab thickness. Key benefits include: • Quicker Installation Contents Specification and Design 41 Load Tables 43 Fire Performance 48 Dramix® Load Tables 50 No temporary supports required under most conditions. A wide range of accessories allows for easy installation of ceilings and services. • Technical Support 42 Kingspan Toolkit software includes comprehensive composite floor design software which allows the user to easily select the right Multideck solution. The design software is available for download from the web site www.kingspanstructural.com. The Multideck design department provides a comprehensive engineering and advisory service to specifiers and end users on the use of the Multideck range of composite decks.

Multideck 80-V2 Load Tables 1 The table shows the maximum span in meters of the Multideck product for the applied loads and slab depths shown. Values are shown for each gauge where the deck is single span or double spans, plus values for propped spans during construction. 12 Deflection under construction loading (wet concrete etc) has been limited to that stipulated in BS5950 Part 4 1994. At the composite stage the suggested maximum ratio of slab span to slab depth are 35 for NWC and 30 for LWC to control deflection. 2 Construction stage span capacity are generally noted under the 4kN/m2 load...

Multideck 80-V2 Fire Performance – Mesh 1 The fire resistance tables for Multideck 80-V2 on the following pages are based upon fire test data from full scale tests performed at the Warrington Fire Research Centre UK, April 1991. 4 The fire resistance load tables are for continuous spans only with no propping. For 2 hour fire rating or propped and single span conditions use the Kingspan Toolkit Software or contact Kingspan Technical Services. 2 All stated slab depths comply with the minimum fire insulation criteria of BS 476: Part 20 1987. 5 Minimum laps should be 300mm for A142 mesh and 400mm...
