Abstract:
|
Dynamic analysis of the arch bridge is performed using time history of acceleration for the
input motion. The prototype of the structure is a transport bridge in Bulgaria. Three real
accelerograms of strong earthquakes with motion characteristics typical for the Balkan Peninsula
region are considered. Finite element model of the structure and a body of ground and filling
material is created by the Plaxis 2D software. Dashpots are applied as supports of the soil-structure
system to simulate the infinite soil space in the numerical FE analysis. The Hardening-Soil-Small
(HSsmall) constitutive model is used for describing the soil mechanical behaviour. This model
handles a large number of material parameters and takes into account the degradation of the soil
stiffness subjected to seismic loading. An additional viscose attenuation of 5% for the soil is
introduced. Analysis and interpretation of the results are carried out.
