Recommended Core Wall Thickness for Highrise Concrete Buildings (Flat plate)

The table below shows the common thickness of the core wall for SDC C. The suggested thickness is in the range of h/140-h/160, where h is the total height of the wall. For SCD D, the same thickness might be sufficient with the addition of moment frame, outrigger, frame tube, etc. Also, the reduced thickness in SDC C is also possible when used with a dual system.

The value of thickness in this table can be a useful guideline for the design of buildings. Detailed analysis is necessary to confirm the wall strength and stiffness to satisfy the design.
