Lintel measurements

I miss a better definition in the building projects, since in many cases they are limited to name the lintels within the descriptions of other items such as “…including proportional part of lintels, jambs…)”, leaving too open the options of choice by the contractors.

I thought of writing this article when I saw for the umpteenth time some lintels made with prestressed joists.    Evidently the system seems to work, but I find this solution horrifying, so I decided to write this article to comment on the characteristics that I think lintels should have.

As I always say, I do not intend to make a thesis on lintels, as there is extensive documentation on the subject, but I do intend to mention the points that I consider most relevant on the execution of lintels.

In principle, as a general definition we can say that lintels are in charge of receiving the weight of the elements above the opening and transmitting it to the jambs, that is to say, to the sides.

Window lintel detail

I am having a house renovation and the architect-builder tells me that the lintel of a window that is going to open in one of the load-bearing walls is going to be 100x100x1700 mm and two 12 mm steel bars in each leaf.

I wonder if this is a product of your experience or of a previous calculation. What is certain is that these are the same measurements as in another lintel installed in another part of the house, with totally different conditions.

It seems that you need help and it is better that a technician advises you with knowledge of the stresses that this lintel has to support, because what your “architect-builder” (???) says does not make sense because of the exaggerated slenderness and the absence of stirrups. Besides, if the opening has a span of 1.70 m, I doubt very much that “anything” as jdl says, either because it is not enough or because it is too expensive.

Let’s see, isn’t the calculation of a lintel an architect’s job? The one who is doing the reform assures me that this is the way he is doing it. But if someone thinks that it can be wrong, let him explain how it is calculated.
