The tension forces created by the overturning uplift and wind uplift, counteracted by dead load, are used to design hold-down connections, calculate hold-down displacement for deflection analysis, and
The program also calculates compression forces at the other end of the shear wall segment, created by the combination of dead and overturning forces, counteracted by wind uplift, for your information in designing vertical force transfer elements. It shows these forces in Elevation view, but not in the Design Results or in Plan View.
For compression forces, dead loads are not considered to be counteracting and the regular (non-counteracting) load combination is used for them. Refer to Dead Load Component for more details.
When there are offset openings or other plan irregularities, it is possible for the tension force on one level to combine with a compression force on the level below. Tension and compression forces from hold-downs at the end of adjacent shear segments on the same level are not combined.
