Due to increasing demand and application of grouted extruded-
strand tendons, need for analysis of tendon characteristics for design and construction exists. Measured for this paper were friction coefficients and strand tensile force distribution of horizontal circumferential tendons of a nuclear containment structure. Results indicated that grouted extruded-strand tendons had very low curvature and wobble friction coefficients (μ = 0.0277/rad and k = 0.0006/m [0.00018/ft]) in comparison to that observed for grease-filled bare-strand tendons. Furthermore, individual strand tensile forces in grouted extruded-strand tendons achieved lower standard deviation than that of bare-strand tendons.
