With the use of the Robot Finite Element program, MFD provided a solution for an easily transportable, rapid deployment grillage system to support telecoms structures. Our structural models include the antenna support structure, to which we have applied wind and dead load combinations, including, where required, a hinged lowering case. This approach fully establishes the deflection performance of the system and allows the weight and stiffness of the design to be optimised. Kentledge requirements are fully established in the design process and a variety of anchorage solutions provided. All design work is undertaken to Eurocode requirements.
