2015 Guidelines for Detailing of Reinforcement in Concrete Structures EC2 & ACI

RECOMMENDATIONS
1. Joints (a) and (b) can transmit stress. Joint (c) can only transmit
horizontal bending stress. Joints (a) and (b) may require corrosion
protection in the area around the reinforcing bar that crosses the crack
if significant amounts of water seep in through the outer side of the
member.
2. Joints (a), (b) and (c) are scantly waterproof.
3. Joints (d) and (e) are fully waterproof.
4. Vigorous vibration must be conducted with extreme care around
water stops.
5. The water stop should penetrate at least 30 cm into the wall
foundation. Welding must be performed very meticulously in long
splices.
6. The beveled and sunken edges in joints (a), (b) and (e) must reduce
the wall section by at least 25 per cent to ensure that the crack will form.

2015 Guidelines for Detailing of Reinforcement in Concrete Structures EC2 & ACI

RECOMMENDATIONS
1. The failure to make J-J joints in (a) and (b) places horizontal tensile
stress in the stems and may induce torsion in the footings. In this case,
the members affected should be designed accordingly.
2. Expanded polystyrene may be replaced by any readily compressed
material.
3. The seal for joint (d) should rest on the polystyrene.
4. Vigorous vibration must be conducted with extreme care around
water stops.
5. The water stop should penetrate at least 30 cm into the wall
foundation. Welding must be performed very meticulously in long
splices.
2. STATUTORY LEGISLATION
None in place.
3. RECOMMENDED ALTERNATIVE CODES - See ACI (29).
4. SPECIFIC REFERENCES - See Chapter 14 in (27).

CANTILEVER RETAINING WALLS FILLAND DRAINAGE

RECOMMENDATIONS
1. Angle e must be calculated.
2. Granular fill should be used to ensure effective drainage. Otherwise,
the thrust cannot be assessed using the usual Rankine and Coulomb
theories on earth pressure.
3. For water proofing the wall there are two systems, (b), (c). In solution
(b), waterproofing consists of a mere coat of asphalt paint. In (c), a
waterproofing membrane is used.
4. Alternative (c) is the solution of choice when water tightness must be
guaranteed.
