RoofDek Quick Selector from Tata Steel
The increasing complexity of roof decking projects makes any new software aimed at easing the process very welcome indeed. Earlier this year Tata Steel introduced RoofDek Analysis Software, allowing structural engineers and specifiers to conduct full deck analysis to Eurocodes 3 and 9. The company has now launched a new online tool to further improve its service.
The Tata Steel RoofDek Quick Selector is a web based structural analysis tool. It allows a user to rapidly select the right structural roof deck for a project on a PC or tablet, including iPad.
“The program does two things simultaneously. It provides an optimised RoofDek specification, and it also allows the user to choose an alternative RoofDek profile,” explained Adrian Wallwork, Tata Steel’s Product Manager – Structural Decking Products.
“The Selector page opens with pre-populated span and load figures as an example. Users can then modify these to their own requirements to find the right decking profile for a given project.
“A suitable decking profile for both single and double span applications is then displayed.
“The pre-filled information is suitable for a general roof deck application, but of course may not be suitable for any particular project.
“The user can therefore edit all the input data to suits the project; a steel or aluminium deck, perforated or not perforated and the support type. Deflection limits under imposed and wind load can be set separately.
“Loads can then be input. Unfactored loads are required, as the program applies load factors to them. Separate provision is made for live load, imposed dead, wind suction, wind pressure, general snow, snow drift and construction line load.
“Each time new information is added, it is evaluated and the deck selection may change accordingly. The user can also try different decks from the dropdowns at any point if required.
“The whole exercise is carried out on one screen and the page may be printed out as record of the design. Calculations are carried in accordance with Eurocode 3.”
