Parapets often go unnoticed on modern houses, as they can appear as the line of a flat roof.

Where are parapet walls used?

Uses of Parapet Walls

To provide safety for humans when they are on the rooftop and in case of bridges to prevent vehicles from falling off . To hide and prevent the equipment and machinery on the rooftop. To prevent the entrance of dust through the air on the rooftop.

What is the minimum height of a parapet?

To prevent negative bending moment and uplifting of roof slab, providing a structural support to roof structure, the minimum height of parapet wall above roof surface should be 30 inches or 2.5 feet.

What is a stepped parapet?

The top of the parapet wall projects above the roofline and the top of the brick or stone wall is stacked in a step pattern above the roof as a decoration and as a convenient way to finish the brick courses. A stepped parapet may appear on building facades with or without gable ends, even upon a false front, however.

What is bridge parapet?

A bridge parapet is a safety barrier that is installed on the edge of a bridge, retaining wall or similar structure with a vertical drop, providing protection for vehicles and pedestrians.

What is the height of parapet wall?

The minimum standard height of the parapet wall should be 3 feet. The parapet wall never is constructed less than 3 feet in height. At this height, the wall protects and ensures safety. The minimum thickness of the parapet wall is 9 inches.

How do you calculate parapet walls?

Parapet Wall Design

1. Since it is free at the top, it will act as a free cantilever.
2. Calculate the axial stress (σ_a) due to the self-weight.
3. Calculate the wind pressure on the wall.
4. Calculate the bending moment induced by the wind loads at the base level.
5. Calculate the bending stress(σ_w) at the based level.

Can a parapet wall be used as fall protection?

According to OSHA guidelines, parapets have to meet the same height requirements for fall protection as any other rooftop fall protection device. The regulations state that parapets, guard rails, and roof safety railings have to be 42 inches tall, plus or minus 3 inches, to provide adequate fall protection.
