Design of formwork

Design of formwork

To design formwork, we can refer to ACI318M-02 in section 6.1 as below:
6.1.1. Forms shall result in a final structure that conforms to shapes, lines, and dimensions of the members as required by the design drawings and specifications.
6.1.2. Forms shall be substantial and sufficiently tight to prevent leakage of mortar.
6.1.3. Forms shall be properly braced or tied together to maintain position and shape.
6.1.4. Forms and their supports shall be designed so as not to damage previously placed structure.

6.1.5. Design of formwork shall include consideration of the following factors:
  (a). Rate and method of placing concrete;
  (b). Construction loads, including vertical, horizontal, and impact loads;
  (c). Special form requirements for construction of shells, folded plates, domes, architectural  
        concrete, or similar types of elements.
6.1.6. Forms for prestressed concrete members shall be designed and constructed to permit movement of the member without damage during application of prestressing force.
