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.

Once your walls are uneven you can build a slanted roof to fit. Some of the prominent examples of the one way slabs are the cantilever slabs chajjas and verandahs. 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. Roof terminology is also not rigidly defined.

Design a one way slab for the inside of a building using the span loads and other data given in figure 1. A roof that slopes in only one direction is called a shed or pent style. Roof type chart 1. A slanted shed roof can easily be built if one of the walls of the shed stands taller than the opposite one.

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. Roof shapes differ greatly from region to region. The intent is to create a uniform edge on the outside but a varying profile on the inside along the sloping roof. 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.

Longer span l shorter span b 2. The load on the slab is carried by the short span in one direction. However main reinforcement bar and distribution bar in transverse direction. The main factors which influence the shape of roofs are the climate and the materials available for roof structure and the outer covering.

Usages vary slightly from region to region or from one builder or architect to another. It s steep pointed roof which extends all the way to the ground. The bonnet roof is identified with the extending ledge around the base of the roof. It is a common roof on sheds and other outbuildings and is frequently used on carports patios porches and small additions to a house.

Basically a slanted roof style is a flat roof tilted high up at one edge to create a very steep slope. It also is often used on dormers extensions built on a basic roof to provide more light or space inside. The shorter span of one way slab is provided with the main reinforcement while the longer span is provided with the distribution reinforcement. The other part of the.

The butterfly roof is an. One way is to design the roof to have a parapet wall covering the roof edge.
