<p>The paper provides a brief overview of recently developed fully coupled 3D chemo-hygro-thermo- mechanical model for simulation of chloride induced corrosion, before and after depassivation of steel as well as its consequences on degradation of reinforced concrete structures. The applications of the model are illustrated on three numerical examples. The aim of the first numerical example is to demonstrate the influence of cracks in concrete on transport processes and on depassivation time. In the second and the third numerical examples processes after depasivation of reinforcement are analyzed in order to study the influence of concrete quality, water saturation and cracks in concrete on corrosion current density of a macro cell; influence of rust transport into the concrete cracks and pores on damages in concrete as well as influence of corrosion on bond resistance. The numerical results are in good agreement with the available experimental observations, what leads to the conclusion that the model is able to realistically predict corrosion of reinforcement in concrete.</p>

<p>Serving to community, they are often exposed to public judgement, especially city bridges, which are continuously seen by many viewers on the bridge and from the different angles in urban setting. Therefore, it is necessary to design not only reliable, durable and economical bridges, but also aesthetically pleasant structures. To design the bridge as a new city landmark, which meets the requirements of large traffic volumes of vehicles and light urban railway as well as intensive but comfortable pedestrian transport, a new approach to bridge design is required.</p><p>Structural-architectural approach, illustrated by beautiful bridges, which harmoniously fit into the urban environment on decent (Trogir Bridge) or representative (new bridges in Zagreb) way, designed by Bridge Division at Faculty of Civil Engineering - University of Zagreb, will be shown in this paper. Respecting the known aesthetics values, for Bundek Bridge a unique structure is formed, which is already applied in the new airport terminal design, but it can be also transformed for other future landmark buildings, e.g. central metro station, as a modern style of the 21st century Croatian capital.</p>
