Next, design recommendations are made for the design of pretensioned caps as part of the original substructure design. The use of ‘T’ headed main reinforcement, dropped bent caps, or smaller diameter longitudinal reinforcement types and ensure pile fit within the cap dimensions and relative to the reinforcing steel. For this type of structure the load is transferred almost directly to the supports by means of an arch mechanism. Pile: Deep foundation components including piers, caissons, and piles. Johnson Roy H. For longitudinal deck reinforcing, bar lengths of 30 feet are preferred, except for one odd length at end of run. Concrete for the deck and column was assumed to have a 28-day strength of 28 MPa (4 ksi). Detail an open joint between the bents.

Steps to protect this exposed reinforcement from further corrosion are evident from the highly uneven Figure 2. and 12 mm 11. Combine the definition from scratch in IDEA with the definition by the DXF file. Analysis of the system confirmed that it is a cost effective technique to increase load rating for concrete pier cap applications. The longitudinal reinforcement of the pier was protruding by around 1500 mm beyond top of pier. Tension piers are found most commonly supporting the lateral system. 3. As such, Bureaupolicy requires designers to check if the pier cap formwork for typical frame and T-piers can be removed when the concrete strength of the pier cap reaches 2. The new pier cap system offers benefits in terms of economy and quality management, and it can be constructed more rapidly than the conventional pier cap and fully Less reinforcement may be used as long as “the area of tensile reinforcement provided is at least one-third greater than that required by analysis. There was insufficient bond length for the structure to behave like a cantilever beam. 17) can be used to carry all or part of the cap formwork. 5) Hoops/ spirals extending from Column/Piles into the Bent Caps or Footings are covered elsewhere in the table. 5 =3405 ksi , Columns and Drilled Shafts The modular ratio of reinforcing to concrete should be rounded to the nearest whole number. remove free exposed reinforcement of cap.
