Most frequent questions and answers

PolyStringer is inevitable for design of concrete diaphragms. PolyStringer determines which forces the diaphragms is exposed to in connection with redistribution of forces between shear walls. An example of this can be seen in the video below.

The reaction can either be defined manually, if they are determined elsewhere which often would be the case for rigid diaphragms. The reactions can also be determined directly in PolyStringer, this would lead to solutions better suited for the diaphragms, which is beneficial for more flexible diaphragms.

To add or remove a stringer click on the green + or – button next the measure lines. The distance between the stringers can modified by clicking on the length. Units or number of decimals are changed in the settings menubar.

In cases with large size differences in the model, the scaling function can be used to give a better overview of the whole model. This is done by moving the scale slider, which is found above the calculate button.

PolyStringer allows for manually entering of the reaction force. This is beneficial when they are calculated elsewhere, as in the case of a rigid concrete diaphragm with flexible shear walls. The manually entering is done in the box to the right of the checkbox and will appear as a blue arrow on the model when enter is pressed.

When the reaction forces are left to PolyStringer they will automatically be determined in the way that minimizes the required reinforcement in the model.

If a shear field I light gray, as seen in the picture below it is a sign that it cannot be activated. This is most likely due to it not being surrounded by four stringers.
