چکیده
In this paper, a design procedure for mono-anchor head anchoring 2360 MPa high-strength steel strand is proposed. The performance criteria of the existing anchor based on PTI (Post-Tensioning Institute) have been reorganized so that they can be evaluated plastic hoop strain appearing at top wedge hole. order to does not exceed permissible standard, stress and deformation mechanisms were investigated. It was confirmed external force locally concentrated hole due interaction between components anchorage device. An investigation finite element method conducted identify degree concentration location establish relationship with strain. analytical according variables head, in process, static load tests material create an model reflects actual behavior system. equation established regressionally strain, which criterion, calculated configuration yield strength head. Following proposed procedure, properly determined when determination limited supply demand. addition, space during construction device, dimensions device small size determined, appropriate determined.

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

متن کاملBond of High Strength Concrete with High Strength Reinforcing Steel
This paper presents a study about the bond of high strength concrete with high strength steel. Fourteen pull out tests were carried out to determine the bond. The concrete strength was about 70 MPa and the steel was a 500 MPa grade. Bar diameters used were 12, 16, 20, 25, 28, 32 and 36 mm. In order to investigate the effect of cover, each test was done twice, once in a 240 mm diameter concrete ...
متن کاملImproved Material Models for High Strength Steel
The mechanical behaviour of the three advanced high strength steel grades, Docol 600DP, Docol 1200M and HyTens 1000, has been experimentally investigated under various types of deformation, and material models have been developed, which account for the experimentally observed behaviour. Two extensive experimental programmes have been conducted in this work. In the first, the dual phase Docol 60...
