Simulation of the load and stress of the bearing capacity in the Lira software module on the example of a pile gridgage bush

The article presents materials for modeling a pile foundation represented by a bush grillage of three structural elements for the design of buildings and structures without taking into account the joint work of the foundation and structure. A technique for modeling a pile foundation using numerical software modules such as LIRA-CAD is proposed. The methods used in LIRA-CAD are based on the relationship between three types of non-linearity of elements. Using a real example, the simulation of the impact of the load on the pile grillage was carried out and the relationship between the load and the critical stress of the structural element was revealed. The destruction of the model occurred in the established range at a critical load of 1000t.
