Reconstruction of the Oldest Reinforced Concrete Bridge in Slovakia in Krásno nad Kysucou

Properties of Old Concrete Built in the Former Leipziger Palace

The former Leipziger Palace in Wrocław (Poland) was built on the site of a riding school, from 1872 to 1874, by the banker Ignacy (Ignatz) Leipziger.…”

“…Then, we compared the determined mean in-situ compressive strength values with the regulations, guidelines, and investigations performed on old concretes from the period of erection and rebuild for the former Leipziger Palace. Paulík [17] reported, for the Monier type arch concrete bridge completed in 1892, an average concrete cube compressive strength from 25.8 MPa to 29.9 MPa, with an average bulk density of 2080 to 2140 kg/m 3 . Hallauer [69] indicated a compressive strength equal to 18 ± 7 MPa for concrete building in a structural element of a river canal built in 1896-1900, and 6.63 ± 2.45 MPa for the concrete elements of a pier built in 1908-1919.…”

The real static behaviour of historic bridge in town Krásno nad Kysucou in Slovakia

“…Its two spans have clear span as much as 16.8 m [4,5] The thickness of the arch changes in the transverse direction as well as the longitudinal direction. The thickness in the longitudinal direction is changed from 400mm in the arch spring to 200 mm in the middle of the first arch (arch top) and 190 mm in the arch top of the second arch.…”

“…There is concrete overlay with plain concrete above the base arch, which has reinforcement in both surfaces. The overlay reaches a thickness up to 600mm in the arch springs and decreases to the 1/3 of span about [4,5].…”

A 95-Year-Old Concrete Arch Bridge: From Materials Characterization to Structural Analysis

“…In most countries, there are old bridges that require maintenance, renovation, or reconstruction [ 3 ]. In the literature, it is possible to find many interesting investigations related to the process of testing and repairing old concrete bridges [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ] or to the structural analysis of old bridges [ 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. Reconstruction and renovation of old bridge structures and adaptation to new traffic loads are complex issues often requiring not only the experience of civil engineers, but also that of the scientific community.…”
