    Structural behaviour of four legged tubular steel lattice towers under wind loads
    (CI-Premier Pte Ltd, 2011) Gücüyen E.; Erdem R.T.; Seker S.; Gökkus U.
    Latticed steel towers are widely used in a variety of civil engineering applications. In this paper, structural behavior of 50 and 75 meters lattice towers which are made of tubular sectioned frame members under 160km/h wind velocity that causes wind force into structure and have 10m2 square antenna area are investigated. The structures (160-10-50, 160-10-75) are handled in two types as space truss composed of pin-jointed (Model A) and rigit main legs surround space truss composed of pin-jointed (Model B). Wind force is based on Gust Factor and calculated according to EIA-TIA 222-F (Structural Standards Abstract for Steel Antenna Towers & Antenna Supporting Structures) code. The aim of this study is obtaining the effective periods, mass sources, interstory drift ratios, maximum displacements of peak points and maximum frame forces of four structures which have different joint connections and height to determine the safety of them.
