Important news in the latest update of the GeoStru software Retaining walls – MDC, in fact, it is now possible to design and verify retaining walls of the gabion and block type. In this article, we will quickly look at how to set up a gabion and block wall.<\/p>\n

Premise on calculations in gabions and blocks<\/h3>\n

In MDC, Resistance verification is carried out in all sections corresponding to the steps or to the separation between the gabions, as well as for the intermediate ones at the points of discontinuity. The rectangular section press-inflected and shear stressed, consisting of non-tensile reacting material or with weak resistance, is checked. For gabion walls, the tensile strength of the material is always assumed to be nothing.<\/p>\n

The reagent section will turn out to be a partialization\u00a0of the whole one, and only in it will a certain distribution of internal tensions be active. In general, if the section is entirely reactant, the normal stress diagram will be trapezoid, possibly intertwined;<\/p>\n

If the section is partialized and the material is a non-tensile reactant, the diagram of the reacting part will be triangular with a point of null at the neutral axis; If the section is partial and the material has a certain tensile strength, the diagram will be butterfly-shaped, with a minimum value equal to the maximum tensile strength and a maximum such that the integral of the pressures balances the stress system.<\/p>\n

How to set up a gabion wall<\/h3>\n

As soon as you start MDC, in the main bar, in the “Type” section there is the novelty: the Gabions<\/strong> tool (Figure 1).<\/p>\n

Pressing the button will disable all other functions that do not come into play with the design of gabions or blocks (Figure 2).<\/p>\n

Geometric data and loads<\/h3>\n

As mentioned, as soon as the gabion type has been chosen, the software itself will guide the user to enter the wall data by keeping the “Geometric data and loads” tool active as shown in Figure 2, which once activated will open the window where to set the geometry of the gabion or block wall (Figure 3).<\/p>\n
