## Materials and Armatures |

This window enables wall and pile materials and armatures to be determined and of their verification parameters.

Reinforced concrete verification parameters

Ratio between stretched and compressed reinforcement

The ratio between stretched and compressed reinforcement in each section is held to the value requested by the user.

Distribution steel

Distribution steel quantity is calculated as the user selected percentage of the stretched reinforcement of the most reinforced section.

Wall

Material properties

For concrete typical cubic resistance value and specific weight are required.

For reinforcement steel the required values are typical yield strength ( fyk) permissible tension (for permissible tension verification), the elastic modulus the homogeneity ratio and the cover value.

Stem bars - Footing bars - Barre dente - Distribution steel

For each of these elements it is possible to specify differentiated bar diameter, and minimum and maximum number of bars.

Based upon these parameters the program attempts verification at various vertical levels, starting with the minimum and proceeding up to the maximum number of bars, and if these verifications fail, the diameter is increased until verification succeeds.

Lap splice bars

There where the reinforcement bars anchored in the footing, do not extend for the full height of the stem, additional bars extend to the full height these are spliced to the original ones. The user is requested to specify the anchorage length of the original bars extending above the footing.

Pile

Material properties

For concrete typical cubic resistance value and specific weight are required.

For reinforcement steel the required values are typical yield strength ( fyk) permissible tension (for permissible tension verification), the elastic modulus, the homogeneity ratio, and the cover value.

Longitudinal bars - Tie bars - Tubular armature

For reinforcement steel the required values are typical yield strength (fyk) permissible tension (for permissible tension verification), the elastic modulus, the homogeneity ratio, and the cover value.

If the pile is also reinforced with tie bars and or longitudinal bars, diameter and number/separation are requested.

For tubular armature internal and external diameter are requested, however selecting from a drop down list of types these data are inserted automatically.
