Development Behavior for Post-Tensioned Self-Centering Steel Connection under Cyclic Loading
Abstract: One of the newest
steel beam-column joints to replace conventional welded connections,
post-tensioned connection steel is with the upper and lower angles. In this
connection are high-strength steel strands that parallel beam web and angles
between beams and column. Actually high resistance strands and upper and lower
angles respectively are provider centralization properties and energy
dissipation capacity of the connection. The benefits of post-tensioned steel
can be used in connection with the centralization and lack of relative
displacement (drift) persistent, stay elastic core components such as connecting
beams, columns and fountains connection, appropriate initial stiffness and
joint manufacture with materials and traditional skills. . In this study,
numerical modelling in Abaqus software, the results of the analysis were
compared with the results of laboratory samples and the results showed that the
two together are a perfect match. After validation, parameters influential
centrist connection then pulled the thick angles in three numerical models were
evaluated. The results show that by
increasing the thickness of the angles, increase energy dissipation capacity
and ductility connection and the β₁ value does not experience tangible changes
with changes in angle thickness.
