Performance of Circular Reinforced Concrete Bridge Columns Under Bidirectional Earthquake Loading
Author: Mahmoud M. Hachem
Publisher:
ISBN:
Category : Bridges, Concrete
Languages : en
Pages : 496
Book Description
Describes the dynamic testing of 4 circular reinforced concrete bridge columns. The specimens were divided into 2 pairs, with each pair subjected to a different ground motion. Within each pair, one specimen was subjected to one component of the ground motion, while the other was subjected to 2 components. Two analytical studies were carried out for a wide array of column heights, diameters, and axial load intensities. The columns were subjected to large suites of ground motions scaled to match on average the design response spectrum.

Seismic Performance of Circular Reinforced Concrete Columns Under Varying Axial Load
Author: Gianmario Benzoni
Publisher:
ISBN:
Category : Bridges
Languages : en
Pages : 214
Book Description
The behavior of four circular reinforced concrete bridge columns, with different axial load regimes, is investigated. The first unit was tested under constant compressive axial load corresponding to an axial load ratio of 0.35. The second specimen was subjected to a constant tensile axial force equivalent to 0.087 axial load ratio. Two specimens were tested under varying regime of axial load, ranging between the two previous load limits, in order to simulate realistic seismic conditions of outer columns of multi-column bents. Extended comparison between experimental and predicted shear response, from different current equations, is provided.

Seismic Performance of Reinforced Concrete Bridge Columns Constructed with Grade 80 Reinforcement
Author: Tim B. Link
Publisher:
ISBN:
Category : Columns, Concrete
Languages : en
Pages : 73
Book Description
The research presented in this thesis assessed the use of high strength steel (HSS) reinforcement for use in reinforced concrete (RC) bridge columns. HSS is not currently allowed in reinforced concrete bridge columns due to a lack of information on the material characteristics and performance information when used in RC bridge columns. Potential benefits in construction, performance, and economics justify the need for research. This research investigated the performance of HSS (ASTM A706 Grade 80 reinforcement) embedded in half-scale RC bridge columns. Column design followed standard design methodologies used by federal and state highway agencies. Six columns were subjected to lateral cyclic loadings, three columns were constructed with Grade 60 reinforcement and three columns were constructed with Grade 80 reinforcement. Results indicate that the columns constructed with Grade 80 reinforcement achieved similar resistances and displacement ductility values when compared with the reference columns constructed with Grade 60 reinforcement. The columns constructed with Grade 60 reinforcement showed larger hysteretic energy dissipation and typically exhbitied larger curvature ductility values than the columns constructed with Grade 80 reinforcement. The effects of the longitudinal reinforcement ratio and moment-shear span ratio on column performance were similar between columns constructed with Grade 60 reinforcement and columns constructed with Grade 80 reinforcement. The results from this research present a promising step towards the implementation of Grade 80 reinforcement in the design and construction of RC bridge columns, within the bounds of the variables used in the testing program.
