‘MOMENT’ DEAD END ANCHORAGE

‘MOMENT’ MULTISTRAND ROUND SYSTEMS:

A method of reinforcing and pre-stressing concrete, masonry and other structural elements. Today, it is used for a wide range of applications including office buildings, condominiums, hotels, parking structures, slab-on-ground foundations, ground anchors, storage tanks, stadiums, silos, and bridges.

The systems are normally adopted for bonded tendons. The tendons consist of a bundle of strand with a nominal diameter of 0.5" (12.7 mm.) or 0.6" (15.2 mm.). The number of strands per tendon can be from 4 strands up to 42 strands of diameter 0.5" or 31 strands of diameter 0.6". The strands in the tendons are contained in one round duct which is made of corrugated galvanized metal.

The strands are individually gripped in one anchor head unit and transmit their pre-stressing force by means of anchor plate casting unit. For each anchor size, special spiral reinforcement is provided at the anchor plate casting to give adequate splitting reinforcement for bustling stresses developed at the anchorage zone. The strands in tendon are stressed simultaneously by means of a multi strand stressing jack from capacity 1,100 KN up to 5,000 KN. The strands can also be stressed individually by means of mono jack.
