Application of modern computational methods in modeling bridge abutments: capabilities of the Lira-SAPR software tool

Abstract

This article considers the application of the finite element method in modeling bridge supports, taking into
account various types of loads - static, dynamic and temperature effects. To achieve this goal, the Lira-CAD
software package was selected, which allows analyzing structures with a full reflection of their geometry,
along with their physical and mechanical properties. This system provides extensive opportunities for
accurately determining load parameters, taking into account seismic and other external influences. The finite
element approach simplifies the calculation process by dividing structures with complex geometry into
simpler elements, which increases the accuracy of engineering analysis and plays an important role in
ensuring the reliability and service life of structures.
