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.
