243 X Nemetschek Structural User Contest 2013 - Category 4: Special Projects Category 4: Special Projects 4 Short description │New Antenna Mast Smilde On 15 July, 2011 a blaze in one of the feeder cables caused the Hoogersmilde guy-wired antenna mast to collapse, causing service disruption to the region and damage to part of the concrete tower. The goal of the client Omroepmasten B.V. was to minimise the disruption by installing a new mast on the concrete tower by August 2012. To mitigate the tight deadline, Iv-Consult and contractor VolkerWessels Telecom completed a parallel fast-track design that would meet the scheduled mast erection date. Scia Engineer was deployed to carry out the analysis of the new guy-wired lattice mast. A geometrically nonlinear analysis of the structure was chosen in order to allow for the high slenderness of the structure and to better represent the behaviour of the cables. A modal analysis has moreover been executed to evaluate the natural frequencies in comparison with the wind actions. Iv-Consult Contact W.M.
