“…The research results showed that the strength and stability of steel structures subjected to prestressing can be significantly improved if the prestressing method is reasonable [4,5]. The prestressed steel structure can save materials and funds, ensure safety, and reduce deformation [6,7]. The prestressed stayed column comprises three parts: the central steel column, which plays a vital role in bearing the upper load.…”

A new type of dual-steering prestressed plate column is introduced. Compared to the previous prestressed strut column, this proposed column considers both bending and constraints at ends. The calculation results indicated that the support plate significantly improves the stable bearing capacity and buckling performance of the core steel column. When compared to the proposed column, the bearing capacity of the three-transverse prestressed beam column is 1.51 times smaller, the single-transverse prestressed beam column is 2.43 times lower, and the non-prestressed column is 4.51 times smaller. Moreover, this study examines the influences of effective length, buckling mode, stress nephogram detail, and prestress value. It explores the possibility of implementing this new type of dual-steering prestressed plate column in practical engineering. In addition, the variety and mechanical models of prestressed columns are expanded and refined.

This study proposes a new type of prestressed stayed column. The traditional prestressed stayed beam-column does not consider the end constraint, whereas the new double-steering prestressed plate column exploits the end constraint while accounting for the middle bending deformation. The sliding form is utilized in this study for the connection part to prevent the prestressed steel cable from breaking at the pole. The results indicated that adding the steering brace improves the core steel column's stable bearing capacity and stiffness. The bearing capacity of the double-steering prestressed plate column is 4.51 times that of the non-prestressed bearing column, 2.43 times that of the characteristic buckling load of the currently prevalent single-transverse prestressed beam-column, and 1.51 times that of the traditional three-transverse prestressed beam-column. The influence of prestress magnitude, effective length, buckling mode, and double-steering plate-column details are investigated. The research findings further enrich and enhance the theory and types of prestressed stayed columns and provide guidance for applying new double-steering prestressed plate-column in practical engineering.
