Lintel Roof Load Width

How wide is the structural opening.

Lintel roof load width.

This is simply done by adding 300mm to the width of the structural opening. Both live and dead load from the roof should be. Finally the value of load the weight which is to be supported by the lintel should also be considered. Nominal height the height of the lintel in mm.

Buildbase has a large range of standard cavity lintels available in a variety of widths from 70mm to 165mm with lengths from 900mm to 3900mm. Loads transferred from the floor or the roof supported by the wall over the lintel. That extra length provides 150mm bearings at each end of the lintel which are essential for achieving the lintel s full performance. For thicker steel and when a lintel with a longer span is required buildbase has a range of medium and heavy duty lintels for 90 105mm cavity widths stocked in lengths from 1200mm to 4800mm.

Followings are the general loads that should be considered for lintel beam design. The clear span between the masonry supports. Rlw is used to calculate the sectional size of some roof members and supporting wall members. Self weight of the lintel.

As standard our steel lintels increase in length by 150mm the two values represent the length of the lintel that the values in that column relate to. Load of the wall above the lintel beam. It is also a dead load. This video looks at roof load width rlw.

The interaction zone is a zone outside the load triangle but within a 60 triangle having 1 1 times the clear span of the lintel at its base. Self weight is a kind of dead load. Spacing should be interpreted as the centre to centre distance between adjacent parallel members. Roof load width rlw and floor load width flw can be determined from as1684 or from the images below.

If it is 600 1200 it means the load span details can be applied to any lintel between 600mm and 1200mm. Example lintel length 150 1800 150 2100mm. Required size for a given span. The load triangle is a 45 triangle having 1 1 times the clear span of the lintel at its base.
