28、Design of tension members for use with structures outside the scope of EN 1993 As a rule, tension members for use with concrete, steel and concrete composite, timber and hybrid structures may be designed as specified in DIN EN 1993-1-11, giving due consideration in the analysis in particular to the
29、time-dependent (e.g. creep, shrinkage) and load-dependent (e.g. cracking) material characteristics. Where necessary, a conservative estimate is to be made of the extremes of stiffness.

In the analysis, the vibration of cables is to be reduced so as to minimize its effect on fatigue. The following shall be consi
35、dered: a) Fully locked coil ropes or cables As a rule, structural measures are to be taken to minimize flexural stress at rope/cable ends. In the assessment, detail category c= 112 N/mm2shall be assumed. b) Parallel strand bundles: The assessment of parallel strand bundles is to be made disregarding
36、 any flexural stress and using detail category c= 167 N/mm2. Flexural stress is to be considered, however, using detail category c= 194 N/mm2, if the cable angle at terminations due to vibrations changes by more than 0,3.
