Ponašanje i analiza AB mostova u zemljotresima
Behavior and analysis of RC bridges during earthquakes
Апстракт
U radu je prikazano ponašanje, i neka karakteristična oštećenja i loma mostova tokom zemljotresa, sa težištem na betonske mostove. Dati su neki uslovi projektovanja mostova prema EC8, primeri i konstruktivni detalji. Mostovi su veoma povredljive konstrukcije podložne oštećenju pri dejstu zemljotresnih opterećenja, pa je neophodno obezbeđenje njihove otpornosti. Seizmička otpornost se postiže: adekvatnim izborom konstrukcije, modela za analizu, samom analizom, ponekad neophodnom dinamičkom interakcijom sa tlom i odgovarajućim izborom detalja. Komentarisana je regulativa za njihovo projektovanje i metode analize mostova na seizmička dejstva. Napomenuti su tehnički propisi i preporuke za projetovanje seizmički otpornih konstrukcija pojedinih zemalja i međunarodnih udruženja uključujući i set Evrokodova 8 (EN1998. Opisane su delimično metode seizmičke analize grednih i kontinualnih mostova. Kod oblikovanja detalja obuhvaćeni su kriterijimi izbora, sa ciljem povećanja otpornosti konstrukcij...e i veće mogućnosti disipacije energije. Ukazano je na potrebu veće primene kontinualnih i integralnih mostova zbog njihove veće trajnosti u odnosu na klasične mostove. Obuhvaćeni su mostovi uglavnom srednjih i manjih raspona koji su najviše zastupljeni u našoj zemlji, a većih raspona u inostranstvu. Zbog ovako obimno postavljene teme rada, a ograničenog broje stranica, pojedinačna poglavlja nisu mogla biti obrađena dovoljno temeljno. Prikazani su primeri: MRO (most), Painter Street most, Antrion Rion most, Hanshin autoput, Showa most, Zečeve Drage vijadukt, Vijadukt Reber, Kovilj natputnjak.
The paper shows the behaviour and some characteristic damages and fracture of the RC bridges during earthquake, with a focus on concrete bridges. The bridges are designed under the conditions defined in EC8, some examples and structural details of bridges are also given. Bridges are very vulnerable and susceptible to damage during earthquake action, therefore, ensuring seismic resistance is essential. Seismic resistance is accomplished by: choice appropriate structure, structural analysis model and analysis itself, choosing dynamic soli interaction model when necessary and by selection adequate details. The paper initially deals with the most common damage of concrete bridges. Designing regulations and analysis methods for common concrete bridges under seismic action are commented upon. The paper gives Technical regulations and recommendations of individual countries and international associations, including the set of Eurocode 8 (EN 1998) for designing seismically resistant structures... are considered. Technical regulations and recommendations for designing seismically resistant structures of individual countries and international associations, including the Eurocode set 8 (EN1998) Seismic analysis methods of beam and continual bridges are described to some extent. In addition to EN 1998-2, the analysis includes the norms from the USA and Japan. The methods of analysis of beam and continuous bridges which are appropriate for the type and importance of the bridges are concisely described and commented upon. Appropriate details are selected with an aim of increasing the structural resistance and potential for energy dissipation. It is indicated that there is a need for an increase in usage of continual and integral bridges due to their longer durability in comparison to the classical bridges. The analysis mostly includes the concrete bridges of medium and small spans, which are the most common bridge types in our country and of larger ranges abroad. Extensive subject of the paper and the limitation in the number of pages made it difficult to describe some of the chapters more thoroughly. Shown examples: MRO (bridge), Painter Street bridge, Antrion Rion bridge, Hanshin Expressway, Showa bridge, Zečeve Drage viaduct, Viaduct Reber, Kovilj overpass.
