Background The use of post-tensioning in girders causes high bearing and compressive stresses in the anchorage zone. In this study, the behavior of the anchorage zone and the interaction between the local and general zone are investigated. The variables included different reinforcements for both the local and general zones for a block of two anchor...

... shown in Fig. (2), there are different types of stresses in the anchorage zone [7,10]. The region ahead of the concentrated force is subjected to high compressive and bearing stresses. Bursting stresses are lateral tensile stresses that result from the deviation of the compressive stresses parallel to the force. This type of stress acts at a region that ...

... well with the experimental cracking pattern of the specimens. For the short direction, the accuracy which must be expected regarding the comparison between the experimental and FEA results is that practically the cracks may not pass through the line of strain gauges for some specimens, causing some difference in their experimental and FEA curves. Fig. ( 20 ) shows the FEA bursting stress contours, in the elastic stage, at the surface of the models for both the long and short direction for the group G1. S11 and S33 represent the stresses Sxx and Szz, respectively. Bursting stresses for the long direction extend in the area between the two anchorage devices. Moreover, for both the long and ...

A new type of square concrete-filled steel tubular (SCFST) column is proposed, which is characterized by transverse stiffened bars inside the steel tube to improve the effective constraint performance of the concrete core. The experiment of this kind of composite material under axial compression was carried out. The results showed that the bearing...
