Prestressed concrete girders are prone to the formation of horizontal end cracks during prestress transfer. These cracks propagate and progress extensively in deeper hollow-type pretensioned girders with larger prestressing forces. This study examine

Hollow PC-girders are hollow along the length of the girder; because of this, the possibility of developing horizontal cracking at their ends at the prestressing time is high. In this paper, a numerical analysis was performed to examine the effects o

Background/Objectives: To professionally meet bridge load demands, hollow PC-girders are recently considered for bridge construction, particularly in Japan. Hollow girders are pretensioned girders, which can be a good alternative for ordinary PC-gird

In this paper, a vibration-based damage detection method was employed to assess a hollow-type prestressed concrete (BS12) girder in two different states using its dynamic characteristics. Once, the girder was assessed in as-built condition presenting

Recent bridge designs have created several efficient pretensioned prestressed concrete girder sections with high levels of prestress. Among them, hollow-type sections are of more consideration in Japan that exhibit good performance in practice. The t

When the prestressing forces transfer from PC-strands to concrete, a region of stress concentration develops at the ends of pretensioned girders, which often results in horizontal cracking during or just after the detensioning process. In this study,

Structural damage is usually presented in the form of decrease in stiffness resulting changes in the dynamic behavior of the structure, and natural frequency of the structure being one of the dynamic variables. A vibration-based damage detection meth
