Behavior of stainless steel–reinforced concrete piers under lateral impact loading
Advances in Mechanical Engineering, 2017 In this study, stainless steel bars with the same diameter were used to replace ordinary stressed steel bars in reinforced concrete bridge piers. An ultra-high drop hammer impact test system was adopted for multiple horizontal impact tests on two groups ...

CRACKING AND REINFORCEMENT CORROSION IN REINFORCED CONCRETE BRIDGES
Doboku Gakkai Ronbunshu, 1987 A study of design recomendations in various countries for the avoidance of reinforcement corrosion suggests that no real consensus exists on the levels of concrete cover and permissible crack width which should be specified.This paper attempts to asses the distribution of cracking, the factors of crack width, and the control of corrosion by reference ...

Skew decks in reinforced concrete bridges [PDF]
Revista IBRACON de Estruturas e Materiais, 2017 Abstract This research investigates reinforced concrete plates and shells with skew reinforcement whose directions are not aligned with the principal internal forces. Two normal forces, one tangential force, two bending moments, and one twisting moment are defined in the plane of the element.

Shear Assessment of Reinforced Concrete Slab Bridges
IABSE Reports, 2013 <p>The capacity of reinforced concrete solid slab bridges in shear is assessed by comparing the design beam shear resistance to the design value of the applied shear force due to the permanent actions and live loads. Results from experiments on half-scale continuous slab bridges are used to develop a set of recommendations for the assessment of ...
