6. SLABS

CHAPTER 6 "SLABS" 13 2.3 Modelling In order to be able to solve randomly shaped plates, they must first be "modelled" with an equivalent rectangular, oblique rectangular or triangular plate. That is, a plate with one of the above shapes must be defined that approximates the real one (geometry definition). OBSERVATION: The need for "Modelling" is evident through the ? plate symbol, indicating that the plate has not been correctly attributed. 2.3.1 Definition of Rectangle Use this command to model slabs with an equivalent rectangular slab. The sides of this slab are parallel to the x and z (horizontal rectangle) universal axes. Select the command and left-click inside the surface of the plate, the one to be modelled. To define the equivalent rectangle: - Left click, on the first top. - Move the mouse diagonally to the second vertex of the diagonal and - Left click to form the rectangle and create the equivalent plate.
