“…However, this steel arch bridge was destroyed in 1991 during the Homeland War. Since the only road connection between the north and south of Croatia was destroyed, a pontoon bridge built by the Croatian Army served as a temporary connection [15]. Meanwhile, the Croatian Road Authority made decision to build a new highway, the first part of which was the new Maslenica Bridge (Figure 1).…”

“…Meanwhile, the Croatian Road Authority made decision to build a new highway, the first part of which was the new Maslenica Bridge (Figure 1). The concrete arch bridge, proposed by the Chair of Bridges at the Faculty of Civil Engineering University of Zagreb, was selected among six alternative preliminary designs [15]. The Maslenica Bridge has a wide concrete superstructure and a narrow fixed reinforced concrete arch with a span of 200 m and a rise of 60 m (Figure 1).…”

“…The Maslenica Bridge has a wide concrete superstructure and a narrow fixed reinforced concrete arch with a span of 200 m and a rise of 60 m (Figure 1). The superstructure consists of eight single-span, post-tensioned precast girders connected by a concrete deck slab cast on site over 12 spans: 6 + 10 × 30 + 24 = 350 m. The superstructure width is 21.42 m and provides four lanes, a median, and safety strips adjacent to the concrete safety barriers on both sides [15][16][17][18][19][20]. Two expansion joints are provided at the abutments, while longitudinally movable bearings are located at both abutments and the piers closest to the abutments.…”

“…Two expansion joints are provided at the abutments, while longitudinally movable bearings are located at both abutments and the piers closest to the abutments. Fixed bearings are located on the two piers near the crown of the arch, while all other piers are fixed to the superstructure [15][16][17][18][19][20]. The bridge piers of a box-shaped cross-section consist of two individual piers connected at the top by a header beam.…”

“…Therefore, a long-span arch bridge carrying a highway over a windy sea channel was chosen for this case study. The Maslenica Bridge [15] has a very important strategic location and for ten years it was the only road connection between the mainland and the southern coastal part of Croatia. On the other hand, the location of the bridge is characterized by a very harsh maritime environment.…”

Assessment of Performance Indicators of a Large-Span Reinforced Concrete Arch Bridge in a Multi-Hazard Environment

et al. 2022

Assessment of a single bridge and management system for all bridges in the network is still a major challenge, although much research has been carried out and implemented in existing networks over the last four decades. This paper presents a case study of a long-span arch bridge, the Maslenica Motorway Bridge, located in a multi-hazard maritime environment. Although special attention was paid to durability during design, the bridge required repair after 20 years of operation. The analysis includes an overview of the design project, structural health monitoring during construction and operation, numerous laboratory and in-situ testing, numerical analysis of structural capacity and remaining service life, and meteorological monitoring of the bridge site. A new approach to bridge assessment is presented that includes not only a deterioration index, but five groups of key performance indicators: (1) safety, reliability, and security; (2) availability and maintainability; (3) costs; (4) the environment; and (5) health and politics. Incorporating all available data and evaluating various aspects of bridge performance provides greater insight into the condition of the bridge, not only at the structure level but also at the network level. The method is applied to the reinforced concrete arch bridge in a harsh maritime environment and evaluation is provided based on the comprehensive data analysis. The key performance assessment procedure and lessons learned from this case study can be applied to a wide range of structures.

Bridge engineering world practice has showed that implicit method of service life prediction, relying on sufficient quality and depth of concrete cover, do not guarantee a 100- year structure lifetime without major, complex and expensive repair works. Bridges exposed to harsh combination of mechanical (static, dynamic, cyclic loading) and environmental (sea salts, de-icing agencies, freeze - thawing cycles, etc.) actions are particularly vulnerable. Two such case studies: Krk Bridge and Maslenica Bridge located in aggressive maritime environment will be analysed in the paper including in-service performance and comparison between measured values on bridges and numerical results obtained by two numerical models for service life prediction: the 3D chemo-hygro-thermo mechanical (3D CHTM) model implemented into the finite element code MASA and the Life-365 model. Both models are capable to realistically predict chloride content in concrete after long-term exposure to seawater. However, the 3D CHTM model, which considers cracks and damage in concrete, anticipates the beginning of steel reinforcement depassivation much more precisely than the other model which doesn’t take concrete damage and cracks into account.

<p>The paper provides an overview of maintenance activities on seven large reinforced concrete arch bridges in Croatia located on Adriatic coastline, built in two periods: in the 1960’s and 1970’s and at the last turn of the century. Inadequate attention to durability issues in combination with very aggressive maritime environment has led to expensive and technically demanding repair works on older arch bridges. The design of more recent constructed bridges took into account the experience from the in-service performance of older arch bridges. Moreover, structural health monitoring systems have been installed on those bridges. As chloride-induced corrosion is the major cause of deterioration of the Adriatic RC arch bridges, a numerical model, which can realistically simulate effects of reinforcement corrosion in concrete is developed and implemented into the finite element code to predict service life of new or already damaged structure.</p>
