One Way Roof Design

The intent is to create a uniform edge on the outside but a varying profile on the inside along the sloping roof.

One way roof design.

A slanted shed roof can easily be built if one of the walls of the shed stands taller than the opposite one. It is a common roof on sheds and other outbuildings and is frequently used on carports patios porches and small additions to a house. 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. The main factors which influence the shape of roofs are the climate and the materials available for roof structure and the outer covering.

One way is to design the roof to have a parapet wall covering the roof edge. The shorter span of one way slab is provided with the main reinforcement while the longer span is provided with the distribution reinforcement. Roof shapes differ greatly from region to region. 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.

Roof terminology is also not rigidly defined. The load on the slab is carried by the short span in one direction. Some of the prominent examples of the one way slabs are the cantilever slabs chajjas and verandahs. Roof type chart 1.

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. However main reinforcement bar and distribution bar in transverse direction. Design a one way slab for the inside of a building using the span loads and other data given in figure 1. The a frame is very easy to identify.

The other part of the. Normal weight aggregate concrete is specified with a density of 145 pcf. It also is often used on dormers extensions built on a basic roof to provide more light or space inside. Usages vary slightly from region to region or from one builder or architect to another.

Significantly cheaper to build than a gable or multi slope roof since there s less material in the roof. It s steep pointed roof which extends all the way to the ground. Basically a slanted roof style is a flat roof tilted high up at one edge to create a very steep slope. Longer span l shorter span b 2.

A roof that slopes in only one direction is called a shed or pent style. Once your walls are uneven you can build a slanted roof to fit.
