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.
Lintel roof load width.
Example lintel length 150 1800 150 2100mm.
Self weight of the lintel.
U0007measure the size of the structural opening i e.
This video looks at roof load width rlw.
Roof load width rlw and floor load width flw can be determined from as1684 or from the images below.
Rlw is used to calculate the sectional size of some roof members and supporting wall members.
The load triangle is a 45 triangle having 1 1 times the clear span of the lintel at its base.
U0007add 150mm minimum bearing to each end.
How wide is the structural opening.
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.
Load of the wall above the lintel beam.
Followings are the general loads that should be considered for lintel beam design.
Finally the value of load the weight which is to be supported by the lintel should also be considered.
Loads transferred from the floor or the roof supported by the wall over the lintel.
24 lintels duration.
This is simply done by adding 300mm to the width of the structural opening.
Self weight is a kind of dead load.
Required size for a given span.
If it is 600 1200 it means the load span details can be applied to any lintel between 600mm and 1200mm.
Nominal height the height of the lintel in mm.
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.
It is also a dead load.
The clear span between the masonry supports.
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.
