Lintel Roof Load Width

Nominal height the height of the lintel in mm.

Lintel roof load width.

Roof load width rlw and floor load width flw can be determined from as1684 or from the images below. Followings are the general loads that should be considered for lintel beam design. It is also a dead load. This video looks at roof load width rlw.

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. 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. This is simply done by adding 300mm to the width of the structural opening. U0007measure the size of the structural opening i e.

Example lintel length 150 1800 150 2100mm. Self weight is a kind of dead load. Loads transferred from the floor or the roof supported by the wall over the lintel. Required size for a given span.

Load of the wall above the lintel beam. 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. 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. Spacing should be interpreted as the centre to centre distance between adjacent parallel members.

The load triangle is a 45 triangle having 1 1 times the clear span of the lintel at its base. How wide is the structural opening. Rlw is used to calculate the sectional size of some roof members and supporting wall members. If it is 600 1200 it means the load span details can be applied to any lintel between 600mm and 1200mm.

That extra length provides 150mm bearings at each end of the lintel which are essential for achieving the lintel s full performance. U0007add 150mm minimum bearing to each end. Self weight of the lintel. 24 lintels duration.
