Optimal placement of post-tensioned self-centering yielding braced systems for braced frame structures
The experience of past prominent earthquakes establishes the fact that the structure’s catastrophes and casualties can be dramatically decreased through the use of self-centering systems. A promising post-tensioned self-centering yielding braced system (PT-SCYBS) has been developed, comprising of two main components, including the post-tensioned wires, exhibiting the desirable self-centering pr...
متن کاملSeismic Behavior of Three-Dimensional Steel Buildings with Post-Tensioned Connections
Abstract—The seismic responses of steel buildings with semirigid post-tensioned connections (PC) are estimated and compared with those of steel buildings with typical rigid (welded) connections (RC). The comparison is made in terms of global and local response parameters. The results indicate that the seismic responses in terms of interstory shears, roof displacements, axial load and bending mo...
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 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 کاملDamage Detection in Post-tensioned Slab Using 2D Wavelet Transforms
Earthquake force, loading more than structural capacity, cracking, material fatigue and the other unpredicted events were undeniable in the structure life cycle in order that environmental conditions of the structure would be changed and treats health. Damage of structures such as crack, corrosion of the post tension cables from inappropriate grouting of the post tension structures and etc. can...
