Lattice beams<\/strong> are constructions or construction <\/a>elements made up of soles, diagonals, uprights and connecting parts<\/a>, which as a whole work on bending.<\/p>\n\n\n\n

A beam has the role of taking the load of the elements resting on it and sending it further, to the resistance elements of the construction.<\/p>\n\n\n\n

As part of the resistance structure of the roof, the trusses represent a non-deformable system of straight bars competing in nodes. These joints can be made with rivets, bolts or by welding. The interval between two nodes is called a panel.<\/p>\n\n\n\n

The composition system of the beams with lattices is made of:<\/p>\n\n\n\n

* soles – contour bars, which edge the structure;<\/p>\n\n\n\n

* lattices – internal bars, which connect the soles together.<\/p>\n\n\n\n

The beams of the beam that connect the soles are connected to them in knots that are considered perfect joints.<\/p>\n\n\n\n

Metal beams have an increased capacity to withstand the loads exerted by strong wind or earthquakes and represent a key element in large-scale constructions.<\/p>\n\n\n\n

The performance of a beam is influenced not only by its shape and physical dimensions, but also by the geometry of the cross section.<\/p>\n\n\n\n

According to the method of composition, lattice beams are classified into:<\/h2>\n\n\n\n

1. Beams with simple trusses<\/strong><\/p>\n\n\n\n

They are formed by a sequence of triangles, without the triangular surface overlapping.<\/p>\n\n\n\n

Also, depending on the grid distribution method, beams with simple grids can be:<\/p>\n\n\n\n

a. Beams with simple lattices with a triangular system<\/p>\n\n\n\n

b. Beams with simple lattices with a rectangular system<\/p>\n\n\n\n

c. Beams with simple diagonal lattices in K<\/p>\n\n\n\n

2. Beams with composite trusses<\/strong><\/p>\n\n\n\n

They are made up by superimposing simple systems so that the assembly has geometric invariance.<\/p>\n\n\n\n

3. Beams with complex lattices<\/strong><\/p>\n\n\n\n

They are characterized by the fact that at least three bars start from each node, and the intersection points of the diagonals are not considered nodes.<\/p>\n\n\n\n
