Reinforced concrete Z-shaped wall section - rczws

This is a section that can be adopted in the modelling of isolated Z-shaped reinforced concrete walls.

Materials and Dimensions

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

The required dimensions are as follows:

  • Web height. The default value is 2 m
  • Side 1 width. The default value is 1.2 m
  • Side 2 width. The default value is 1.2 m
  • Web thickness. The default value is 0.3 m
  • Side 1 thickness. The default value is 0.3 m
  • Side 2 thickness. The default value is 0.3 m
  • Width of Web confined edges. The default value is 0.4 m
  • Width of side 1 confined edges. The default value is 0.4 m 
  • Width of side 2 confined edges. The default value is 0.4 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. Diamond stirrups at the section's rectangular confined edges may be also added.

Important: Re-bar distance d3 is to be measured from the bottom of the section.

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.
