Title: | The estimation of seismic performances of reinforced concrete girder bridges using nonlinear dynamic analysis | Authors: | Rašeta, Andrija Lađinović, Đorđe Radujković, Aleksandra |

The paper applies nonlinear dynamic analysis to estimate seismic performances of reinforced concrete girder bridges. In all analysed variations, the structure of the beam implies the continual girder with four fields (35 m + 50 m + 50 m + 35 m) hinged to the pier tops and the abutments. The piers are completely fixed to the ground with the lengths of 7 m, 14 m and 21 m; hence, 18 diverse combinations of pier lengths have been analysed. Geometric nonlinearity is included via the P–Δ effect, while the material nonlinearity is included into the analyses using the fibre models of plastic hinges. The estimation of seismic performances has been calculated on the basis of the demanded local ductility and the local ductile capacity of the critical cross-sections in the piers of all bridge analysed variations. Artificially (synthetically) generated and recorded earthquake accelerograms have been utilized for nonlinear dynamic analyses. | URI: | https://open.uns.ac.rs/handle/123456789/3293 | ISSN: | 13303651 | DOI: | 10.17559/TV-20140909173504 |
