Elevated rail transit has been developed in some big cities in China in recent years. However, specialized codes for design of the bridges in the elevated rail transit system have not yet been established. Based on the prestressed concrete (PC) box girder bridges on Guangzhou metro line 4, some technical features of design principle and technology requisition, ensemble plan and design load of b...

this paper presents an experimental study on seismic repair of damaged square reinforced concrete columns with poor lap splices, 90-degree hooks and widely spaced transverse bars in plastic hinge regions according to aci detailing (pre.1971) and (318-02) using gfrp wraps. three specimens were tested in “as built” condition and retested after they were repaired by glass fiberreinforced plastic s...

This paper presents an experimental investigation of the mechanical properties rubberised concrete confined with basalt-fibre textile-reinforced mortar (TRM) jackets. The main aim is to evaluate effectiveness TRM confinement scheme on cylindrical specimens by examining five different mixtures (rubber content ranging from 10.5% up 42% total aggregate volume), including a plain reference mixture....

The axial compression strength of concrete columns has been proved to be significantly enhanced by external confinement. In this perspective, the use Fiber-Reinforced Polymers (FRPs) extensively studied. practical applications, FRP-confinement is installed on loaded columns, which can already deformed, while theoretical models neglect aspect. This paper concerns a new experimental investigation...
