The paper presents the results of static and dynamic tests of double layered catenary of the swimming pool building roof in Leskovac. By the comparison of measured and calculated values, a potential was created to correct the mathematical model, and to verify it. Only then, the calculation model for all sorts of static and dynamic load was able to simulate the realistic behavior of the structure. In this paper, the authors presented the basic recommendations in terms of what initial tensile force should be adopted in order to control the stability of such very cost-effective girders.
Key words:
Suspended systems, cable truss, dynamic analysis, structure testing.
TEORIJSKO-EKSPERIMENTALNA STATIČKA I DINAMIČKA ANALIZA DVOPOJASNE LANČANICE
U radu su prikazani rezultati statičkog i dinamičkog ispitivanja dvopojasne lančanice bazena u Leskovcu. Poređenjem merenih i sračunatih vrednosti stvorena je mogućnost da se izvrši korekcija matematičkog modela, a zatim i njegova verifikacija. Tek nakon toga računski model za sve vrste statičkog i dinamičkog opterećenja potpuno realno je simulirao stvarno ponašanje konstrukcije. U okviru ovog rada autori su dali osnovne preporuke u pogledu usvajanja početnih sila zatezanja u cilju kontrole stabilnosti ovakvih vrlo ekonomičnih nosača.
