“…Based on the study, it was concluded that the proposed method can be efficiently used to perform a sensitivity analysis of time-dependent effects of PSC box girder bridges. Moon et al [119] investigated the stress variation and deformation characteristics of a segment box girder bridges during construction, using a sequence analysis. The study concluded that the structural behavior of the girder sections was greatly affected by the thickness of the bottom slab and the position of prestressing anchors, but not by the prestressing sequence.…”

“…Dynamic loads and overloads cause secondary stresses and large shear stresses later producing cracking in oblique sections (Wang 2005). In segmental prestressed concrete bridges with the glued joints of girder segments, cracks generally occur near segment joints and the places where wire bunches are corroded (Darmawan 2009;Darmawan, Stewart 2007;Kamaitis 2008;Liang, Wu 2001;Moon et al 2005;Polodny 1985).…”

The article describes the main damages of box girder viaducts constructed in Lithuania and discusses the reasons for their occurrence. Several viaducts are examined in more detail with regard to their design data and experimental results. Using finite element software "Midas Civil" the distribution of the main stresses was determined in the box and reduced girders of the Pareizgupis viaduct caused by symmetrical and asymmetrical loads. The widths of flexural cracks in the Pareizgupis viaduct are analyzed evaluating the behaviour of prestressed reinforcement suffered from corrosion. The above mentioned program was used to calculate the deflection of viaduct when damage of reinforcement is estimated. The paper examines the possibility to evaluate viaduct durability using the probability methods based on the initial investigation data.

“…During the 1980s and 1990s, researchers focused on the structural analysis [4][5][6][7], since the box girder presented a complex problem. Later, other research topics arose, such as, the structural behavior at different construction stages [3,8], the durability conditions and their effect on the strength conditions [9,10], deflections during construction [11], long-term behavior [12], life-cycle assessment [13,14] and multi-criteria decision making methods applied to the sustainable bridge design [15].…”

This paper presents a study of the parametric variability of post-tensioned concrete box-girder pedestrian bridges. SAMO2 algorithm is used for the parametric study. This algorithm combines SA with a mutation operator, to find the economic solutions. A span-length parametric study analyzes the characteristics for the best design of a three-span deck in which the main span ranges from 30 to 60 m. The depth and the number of strands were adjusted according to span length, while the thickness of the slabs presented the same optimum values in all cases. Results show that the amount of steel and volume of concrete per square meter of deck shows a good correlation with the main span length. This study demonstrates that by increasing the main span length by one meter, the total cost per square meter of the deck increases by 6.38 euros on average. Thus, this paper shows the relationship between the span length and geometrical and steel variables to produce and build a cost-efficient pedestrian bridge.
