Specialist drafting techniques

Civil drafting …

Structural detailing

Services layout Aid to construction Project planning

This presentation … Reinforced concrete Steel reinforcements Bar notation Bar shapes Detailing of reinforcement

Objective ....be able to read, prepare and present a detail drawing of a simple steel reinforced concrete structure.

Reinforcement concrete Concrete  composite material  excellent compression strength

Reinforcement concrete Reinforcements Increase tensile strength, ductility Natural fibre Steel Polymers

Detailing reinforcements Mesh – fabric detail

 Fabric is specified in term of the AS1304 standards.

 Refer to Table 2.6 p2.42 (SB2)  For detailing – the important information are: Type – e.g. F82  Longitudinal / Cross wire pitch – e.g. 200 / 200 for F82  Longitudinal / Cross wire size – e.g. 8 / 8 mm for F82 ; 12.5 / 8 for F1218
