IMPACT

Surface and projecting corners of all components must be designed to

withstand high impact in those locations where impact typically occurs,

e.g., corridors. A reasonable degree of resistance to impact is achieved

by providing two layers of gypsum board, by rails or by covering

projecting, vulnerable corners with metal angles. Proprietary systems are

often designed with this metal angle as a standard item.

334.2

LATERAL LOADS

All lateral stability of the basic partitions, frames for doors, etc., will be

provided by attachments to floor and ceiling. (In those instances where

the capacity of the ceiling is exceeded, additional supports from the

structure above will be required.) Lateral loads on the partitions should be

calculated at 10 pounds per square foot. Deflection for lateral load of 5

pounds per square foot should be limited to 1/360 of the partition height.

Forces introduced by doors and impact from doors must also be taken into

account in the design of the partitions and the door sets.

334.3

VERTICAL LOADS

Partitions must be capable of supporting vertical loads from equipment

weighing at least 100 pounds per lineal foot of wall, with the load applied 6

inches out from one face of the partition. Heavier loads will be floor

supported where possible. In areas where heavier loads are typically wall

supported, e.g., X-ray rooms, the partitions in that department will be

designed to carry loads up to 200 pounds per lineal foot of wall applied 12

inches out from one face of the partition. To achieve this higher loading

capacity, gypsum board on metal studs is required.

Gypsum Board on Metal Stud Partitions

The following table is provided as a basis for the design of steel stud

partitions in various areas of the hospital.
