This paper presents a brief review of equations proposed for calculating the increase in
stress in external prestressing tendons at the ultimate stage. The validity of these equations …

The wide use of external prestressing system to strengthen reinforced and prestressed
concrete members requires the full understanding of the behaviour of the strengthened …

It is generally known that the flexural strength of beams prestressed with external tendons is
comparatively lower than that of members with internal bonded tendons. One possible …

External prestressing is an efficient technology to strengthen existing structures, and using
fiber-reinforced polymers instead of steel in external tendons is advantageous to avoid …

Existing studies have proved that interfaces between the prefabricated layer and the cast‐in‐
place layer significantly affect the static performance of prefabricated concrete structures …

Strengthening of reinforced concrete (RC) beams is the important issue in the civil
engineering practice. One of the techniques that can be applied in strengthening of such …

A database of 253 unbonded tendon-reinforced members was assembled and analyzed
with a focus on Δ f ps. Large scatter was observed and gaps were identified in previous …

To investigate the influence of external prestressing with carbon fiber-reinforced polymer
(CFRP) tendons on the flexural and shear performance of reinforced concrete beams, a total …

The demand to build for a growing urban population conflicts with the need to reduce the
AEC (Architecture, Engineering and Construction) sector's contributions to global CO 2 …

This paper presents a simple method to calculate the increase in stress of the external
prestressing tendons used to strengthen the concrete beams at any loading. First, the …
