Approximation of the general model of bridge supports to finite elements taking into account the specified loads. Analysis of the capabilities provided by the “Lira-Sapr” software complex to solve the tasks set
Abstract
This paper considers the finite element method for approximating the general model of bridge supports taking into account various loads, such as static and dynamic effects, as well as temperature deformations. To solve this problem, the modern software package "Lira-SAPR" is used, which provides extensive capabilities for modeling and analyzing structures taking into account various physical effects. The software allows you to create accurate models of bridge supports, which take into account not only the mechanical properties of materials, but also geometric features, such as the shape and size of elements.Features of the application of "Lira-SAPR" consist in the ability to fine-tune the load parameters and take into account the influence of external effects on the structure, including seismic, wind and operational loads. The package also supports various types of tasks, including static and dynamic analysis, as well as checking the strength and stability of structural elements.The use of finite elements allows you to break down complex geometry into simple elements, which significantly simplifies the calculation and optimization of the structure. As a result, the use of Lira-SAPR for modeling bridge supports ensures high accuracy of analysis, increasing the safety and durability of bridge structures.
