Horizontal Post - Tensioned Connections for I ' Recast Concrete Load - Bearing Shear Wall Panels
Precast load-bearing shear wall panels are used extensively for high-rise construction because of the ease and speed of assembly, and the high quality of the precast panels. The connections between panels are extremely important since they affect both the speed of erection and the overall integrity of the structure. This paper presents the results of a research program conducted to investigate ...
متن کاملMechanism of Corrosion of Steel Strands in Post Tensioned Grouted Assemblies
In this preliminary study, the complexity of the corrosion phenomenon of post-tensioning strands in grouted anchorage assemblies was examined and both physicochemical and electrochemical key technical issues were identified. Measurements of oxygen reduction efficiency in high pH electrolytes were conducted to obtain polarization parameters to be used in modeling. The time evolution of electrica...
متن کامل08398 - Detection of Corrosion of Post-tensioned Strands in Grouted Assemblies
The feasibility and sensitivity of electrochemical noise (EN), electrochemical impedance spectroscopy (EIS), and linear polarization resistance (LPR) for detection of corrosion in post-tensioning (PT) components was investigated. The use of the electrical resistance (ER) technique, as well EIS and LPR, to detect air space corrosion at the grout voids was also explored. The results showed that h...
متن کاملPost-Tensioned Steel Connections Self-Centering Behavior Using the Finite Element Method
Due to lack of the proper and well behavior of steel moment-resisting connections subjected to the great and major earthquakes, excessive researches have been conducted to mitigate the damages on the primary elements and connections. Therefore, elimination of residual drift and increasing the plastic rotation capacity for the connectors in the panel zone are required. The main purpose of this s...
متن کاملComparing Repaired and Undamaged Specimens Test Results of Post-Tensioned Beam to Column Connections
Since, it is essential to provide homeless people by the earthquake with safe, habitable accommodation repairing medium and slight levels of damage at the connection parts should be undertaken. In order to prove that a repaired connection was sufficiently strong, a precast beam to column post tensioned connection was tested in three phases. In phase one, the middle level damage was observed at ...
