Stiffened walls

(1) Walls may be considered as stiffened at a vertical edge if:

• cracking between the wall, and its stiffening wall is not expected, i.e.:

- both walls are made of materials with approximately similar deformation behaviour,

- are approximately evenly loaded

- are erected simultaneously and bonded together

- and differential movement between the walls for example, due to shrinkage, loading etc., is not expected,

• the connection between a wall and its stiffening wall, is designed to resist developed tension and compression forces, by anchors or ties or other similar means.

(2) Stiffening walls should have,

- at least a length of 1/5 of the storey height

- and have at least a thickness of 0,3 times the effective thickness of the wall to be stiffened,

- but not less than 85

(3) If the stiffening wall is interrupted by openings,

- the minimum length of the wall between openings encompassing the stiffened wall, should be as shown in figure 4.3,

- and the stiffening wall should extend a distance of at least 1/5 of the storey height, beyond each opening.

Stiffening Wall

(4) Alternatively, walls may be stiffened by members other than masonry walls, provided that they have the equivalent stiffness of the masonry stiffening wall, and that they are connected to the stiffened wall with anchors or ties, designed to resist the tension and compression forces that will develop.
