Reinforced concrete T-section - rcts

This is a section frequently adopted for the modelling of reinforced concrete beams, with T-, L- or rectangular shapes (to model the L-shape users should set the beam eccentricity equal to zero, and to model the rectangular shape it is also required to define identical values for slab and beam widths).

Materials and Dimensions

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

The required dimensions are as follows:

• Beam height. The default value is 0.6 m
• Beam width. The default value is 0.25 m
• Slab effective width. The default value is 1m
• Slab 1 thickness. The default value is 0.15 m
• Slab 2 thickness. The default value is 0.15 m
• Beam eccentricity. The default value is 0.375 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 legs, as well as the distance between them.

Important: Be aware that re-bar distance d3 is to be measured from the bottom of the section.

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.
3. From version 6 it is possible to define asymmetric flanges thicknesses (see above).
