Strengthening of Reinforced Concrete Bridge

A compressive strength model for confined concrete wrapped with fiber-reinforced polymer (FRP) has been developed which is an extension of Mohr’s strength theory. This model explicitly relates the confined compressive stress, f ′ cc, to the confining pressure, f ′ l.

Design of Slender Reinforced Concrete Bridge

2018-6-8  Forces on columns caused by second-order effects are routinely over-estimated, which results in a waste of valuable resources and in construction difficulties because of high reinforcement ratios. This paper introduces a simplified method for the design of slender reinforced concrete (RC) bridge columns that reproduces the interaction between columns of the structure and its effects on their second-order

Cross-Section Strength of Columns Design Booklet

2017-12-14  This design booklet is concerned with the strength of reinforced concrete cross-sections of concrete columns subjected to combined axial force and bending moment and designed in accordance with AS 3600-1994 and some proposed changes contained herein. It provides rules essential for designers to efficiently detail the main (longitudinal) reinforcement.

Proposed design procedure for reinforced concrete

2019-12-1  In this study, the dynamic response analysis and design of reinforced concrete bridge columns (RCBCs) with square cross-section have been investigated and proposed. The influences of column cross-section shapes, e.g. rectangular section, circular section, or hollow section, on the dynamic behaviours of the RCBC are not covered in the present study, which require further studies.
