The fatigue performance of reinforced concrete beams strengthened with externally post-tensioned carbon fiber-reinforced polymer (CFRP) tendons was examined in an experimental and analytical study.
Externally post-tensioned steel tendons have long been an attractive option for increasing the design loads or correcting strength and serviceability problems in bridge and building structures.
Longitudinal compression and 4-point bending tests were carried out on three types of beams: centrally, internally and externally post-tensioned.
The review covers the near surface mounted (NSM), externally bonded reinforcement (EBR) and externally post-tensioned techniques (EPT) and the corresponding advantages and disadvantages are highlighted.
Experimental data and analytical methods for predicting the ultimate capacity of reinforced concrete deep beams which include the effect of externally post-tensioned CFRP rods are examined.
The present study examined the flexural behavior of externally post-tensioned lightweight aggregate concrete (LWAC) beams under symmetrical top one-point, two third-point, and analogous uniform loading systems.
The comparisons clearly indicated that Δfps and μ measured in the externally post-tensioned beams were lower than those of the internally post-tensioned one-way members with the same reinforcing index.
This paper describes the results of dynamic impact testing on externally axially loaded steel rectangular hollow sections (RHSs) and compares the response to that of externally post-tensioned steel RHSs.
The accuracy of the proposed analysis model was also verified by comparing to the test results of continuous UPT members that included over-reinforced members, internally and externally post-tensioned members, and the members with diverse tendon profiles and various sectional shapes.
The efficiency of the proposed strengthening method using externally applied post-tension rods in reinforced concrete external beam-column joints, which do not comply with any code requirements, is investigated.
"He beat off considerable competition internally and externally for the post but I believe there is no one more suitable to take on this exciting and challenging new remit".
