Masts:
ing. Chmelař, ing. Beneš, 2002-2006
We worked up statical and dynamical calculation of approximately 40 masts and many other lower masts during 2002-2006.Mainly it was calculation of existing structures in the context of increasing load and height.For many of these masts, we have designed changes, reinforcement, extension or new outriggers.We had to collect necessary information by survey and measurement in many cases.The check of mast capacity was also connected with an overhaul of steel structure in many cases.Statical calculations involve analysis of mast dynamical behaviour inclusive numeration of own vibration frequencies, internal forces, deflections and reactions, that are calculated from statical and dynamical wind load and icing load, furthermore checking of steel structure inclusive joints and anchorage with consideration of material fatigue.
