Profiles with contact and with full compression Criteria: Groove width at bottom 33 mm, groove depth 10 mm, groove angle 15 ° Groove dimension: Agroove = ( tan 15° � 10 + 33 ) � 10 = 356,8 mm2 Cross section: 315 mm2 At full compression (gap 0 mm, distance groove bottom – bottom 20 mm) the groove is used with:
315
356,8 � 100 = 88,3 % ( < 100 % )
With this calculation also the tolerances of the concrete segment measurements and the profile measurements have been considered.
