Abstract
Viseći most čini kolnička konstrukcija obješena preko vješaljki na glavnu nosivu užad razapetu između pilona sa sidrištem na krajevima mosta. Kolnička konstrukcija je ukrućena zateznim kabelima ili rešetkama radi sprječavanja vibracija i smanjenja deformacija. Provedena su eksperimentalna istraživanja na visećem pješačkom mostu u Osijeku u svrhu određivanja dinamičkih parametara konstrukcije. Nelinearni numerički model mosta te podmodeli vješaljki napravljeni su iterativnim postupkom koristeći dinamičke parametre dobivene terenskim ispitivanjem. Promatran je utjecaj oštećenja na promjenu sila u kabelima te promjenu vlastitih frekvencija konstrukcije. Potrebno je naglasiti da ako dođe do istovremenog otkazivanja nosivosti više vješaljki, sigurnost i stabilnost mosta može biti ugrožena. Viseći most je predviđen i konstruiran za pješački promet. Zbog moguće potrebe prijelaza servisnih vozila preko mosta izvršena je provjera nosivosti prilikom opterećenja motornim vozilima. Izvršena je i provjera nosivosti spojeva vješaljki na neoštećenom, oštećenom te na modelu prilikom prelaska vozila. Utvrđeno je da nosivost i uporabljivost nosivih čeličnih elemenata nije ugrožena za definirana opterećenja.
Abstract (english)
The suspension bridge consists of a deck suspended over hangers on suspension cables, stretched between pylons with anchorage at each end. The deck is stiffened with cables or a truss to reduce deformations and vibrations. Experimental research was carried out at the suspension pedestrian bridge in Osijek in order to determine the dynamic parameters of the structure. The nonlinear numerical model of the bridge and the sub-models of the hangers were made by an iterative procedure using the dynamic parameters obtained by field testing. The damage effect on the change of cable forces and natural frequencies of the structure were observed. If the load-bearing capacity of several hangers is simultaneously canceled, the safety and stability of the bridge may be compromised. The bridge is designed and constructed for pedestrian traffic. Due to the possible need for service vehicles to cross the bridge, a payload check was carried out during loading of motor vehicles. The load-bearing capacity of the hanger joints was checked for undamaged, damaged and on the model when crossing the vehicle. The capacity and usability of load-bearing steel elements is not compromised for defined loads.
