One Way Roof Design

Significantly cheaper to build than a gable or multi slope roof since there s less material in the roof.

One way roof design.

A roof that slopes in only one direction is called a shed or pent style. Usages vary slightly from region to region or from one builder or architect to another. It is a common roof on sheds and other outbuildings and is frequently used on carports patios porches and small additions to a house. Another is to create a custom gravel stop drip edge flashing piece that changes profile along the length of the roof to compensate for the change in pitch.

Design a one way slab for the inside of a building using the span loads and other data given in figure 1. Roof type chart 1. The load on the slab is carried by the short span in one direction. The butterfly roof is an.

It s steep pointed roof which extends all the way to the ground. Assuming cover 3 4 in figure 1 the minimum thickness for one way slab simply supported l 20 using table 1 aci 9 5 2 1. The a frame is very easy to identify. Once your walls are uneven you can build a slanted roof to fit.

When a slab is supported on all four sides and the ratio of long span to short span is equal or greater than two it will be considered as one way slab. One way is to design the roof to have a parapet wall covering the roof edge. Roof shapes differ greatly from region to region. The main factors which influence the shape of roofs are the climate and the materials available for roof structure and the outer covering.

The bonnet roof is identified with the extending ledge around the base of the roof. Normal weight aggregate concrete is specified with a density of 145 pcf. The other part of the. If both walls are the same height you can either raise one by adding plates to it or you can build a frame for the wall separately and then install this on top of the wall.

Longer span l shorter span b 2. However main reinforcement bar and distribution bar in transverse direction. Roof terminology is also not rigidly defined. It also is often used on dormers extensions built on a basic roof to provide more light or space inside.

Some of the prominent examples of the one way slabs are the cantilever slabs chajjas and verandahs. The shorter span of one way slab is provided with the main reinforcement while the longer span is provided with the distribution reinforcement.
