Reinforced concrete circular section - rccs

This is a section frequently adopted for the modelling of reinforced concrete circular columns.

Materials and Dimensions

Three different materials can be defined; longitudinal reinforcement, transverse reinforcement, concrete.

The required dimension is as follows:

• Section diameter. The default value is 0.6 m
• Cover Thickness. The default value is 0.025 m

Reinforcement

Longitudinal reinforcement bars can be defined in two different ways:

1. by editing the reinforcement pattern;
2. by entering the respective area and sectional coordinates (the latter being defined in the local coordinate system of the section).

Further, the transverse reinforcement may be specified, in terms of the stirrups' diameters and distance between them, as well as to select a circular or spiral arrangement.

FRP Strengthening

FRP wraps may be assigned by selecting the FRP Wrap from a list of the most common products found in the internet, or by introducing user defined values.

Notes

1. The confined concrete region is automatically computed by the program using the R/C cover thickness.
2. All re-bars must be located within the confined concrete region.
