Wind towers - design of flange ring connection
Today, wind power is second largest available renewable resource of energy, with 870 TW (terawatts). Large wind farms, with hundreds of wind towers are big opportunity for steel production industry. Designers and manufacturers of wind towers pay special attention on every single detail, always looking for some new solutions, trying to reduce price of wind towers. Some of the most interesting design and manufacturing details are connections used to assemble sections of tubular steel towers supporting wind turbins. There is traditional and actually more used flange ring connection and on the
other side, as a new proposal which is used more and more, friction connection. In this paper theoretic basis of design of flange ring connection of wind towers is give
Design of class 4 cross section in axial compression according to EUROCODE 3
In this paper theoretic basis of design of class 4 cross section in axial compression according to EN1993-1-5 is given. Design procedure is given as an flow chart and ilustrated with an worked example. Plate buckling is treated localy and globaly through the concept of effective cross sections. Interaction between plate-like and column-like behaviour of panels is carried out thought buckling reduction factors and final effective area of cross section

Stainless steel cross-section resistance according to continuous strength method
Continuous strength method is a contemporary approach to calculation of resistance of stainless steel cross-sections which has been recently developed at the Imperial College of London. The basis of the method is the continuous relation between the slenderness and strain capacity of a
cross-section, nonlinear relation between the stress and strain and the strengthening effects of cold forming. In the paper are presented the fundamental rules for calculation of cross-section resistance
according to continuous strength method; the comparative analysis of design resistance of the compressed cross-section was conducted through a numerical example according to this method and EN 1993-1-4

Čelična konstrukcija sinemapleksa ''STER'' u tržnom centru ''Delta City'' u Beogradu
This paper represents steel structure of the cinema »Ster« which is a part of the shopping mall Delta City in Belgrade. Cinema has six projection rooms with additional contents. There are three levels of structure: main bearing structure, structure of projection rooms and raised floors, gross weight approximately 600 t. All steel columns are free suported. Vertical and roof bracings and stiff composite floors provide stability of structure. Due to complex roof geometry and building particularity, special attentione

Primer primene akustičke izolacije u čeličnoj konstrukciji sinemapleksa ''STER'' u Beogradu
Modern public buildings, such as multiplex cinemas, along with application of state of the art sound effects brings high acoustic isolation demands. Cinemas are often a part of building complexes such as shopping malls with subjects that produce serious level of noise and vibrations. Usage of modern materials, with specific dynamic characteristics, as a base for supports gives a wide range of possibilities in controlling the amount of noise and vibrations transferred to the structure. This paper gives an example of usage of acoustic pads in steel structure of “Ster” cinemaplex in Belgrade
Nosivost na smicanje anker ploče sa grupom elastičnih čep moždanika
Joint between concrete structural member and steel or timber structural member can be realized with anchor plate which is being embeded in concrete structure during the erection. Anchor plate can be connected with concrete structural member using any standard anchor, with anchors made of ribbed reinforcement or, with group of standard head stud connectors as it is described in this paper. This paper also describes a procedure for calculation of anchor plate shear capacity with connection to concrete member realized with group of head stud connector
