To check the maximum column displacement and the maximum distortions of columns, slabs and/or walls in CYPECAD, once the structure has been calculated, open the "Results" tab and navigate to a group where any of these elements are visible.

Next, open the "Envelopes" menu at the top of the interface. 

Maximum column displacements

The "Maximum column displacements" option displays the maximum displacements of the selected column on each floor.

These are the maximum displacement values for all combinations of assumptions associated with the displacements defined in the "General data" section of the "Project", and they refer to the general axes X, Y and Z.

Maximum distortion of columns, shear walls and walls

The "Maximum distortion of columns, shear walls and walls" option displays a list of the maximum horizontal displacements relative to the floor heights for these elements. 

This list begins with a table showing the distortion data calculated for each loadcase and for the selected "Column":

• On each "Floor", its "Elevation" is indicated, along with the height ("h") relative to the level immediately below, and the horizontal offset or distortion on that floor relative to the general X and Y axes, both "Absolute" and "Relative" to the floor level. Furthermore, its "Origin" is indicated, which refers to the nature of the combination of loadcases that produces the maximum distortion on each floor.

• The bottom row shows the "Total" distortion of the column, screen or wall, calculated as the total height from the initial floor to the final floor.

Finally, the "Maximum values" section displays a table showing the values for "Local maximum shift of the columns" (or of shear walls or walls) for each "Floor" and for each case, and in each of the directions, X and Y.

Finally, a table is displayed showing the value for "Maximum total drift of the columns" (or of shear walls or walls) for the entire structure in each direction.
