Abstract EN
Multiscale finite element (FE) modeling offers a balance between computational efficiency and accuracy in numerical simulations, which is appropriate for analysis of seismic collapse of RC highway bridges.
Some parts of structures that need detailed analysis can be modeled by solid elements, while some subordinate parts can be simulated by beam elements or shell elements to increase the computational efficiency.
In the present study, rigid surface coupling method was developed to couple beam elements with solid elements using the LS-DYNA software.
The effectiveness of this method was verified by performing simulation experiments of both a single-column pier and a two-span simply supported beam bridge.
Using simplified multiscale FE modeling, analyses of collapse and local failure of a multispan simply supported beam bridge and a continuous rigid frame bridge were conducted to illustrate the approach in this paper.
The results demonstrate that the simplified multiscale model reasonably simulates the collapse process and local damage of complex bridges under seismic loading.
