Step-by-step guide for novice users of the LIRA-FEM software, which reveals the basics of finite element analysis. In this videoguide you will learn how to create and analyse the model of steel tower in LIRA-SAPR.
In this practical lesson we will get acquainted with the initial data and start working in LIRA-SAPR.
In this video tutorial we will start building a model of a metal tower using the Add Node command.
In this videoguide we continue to create a model of metal tower. We will add braces and lattice by using Add element command.
In this videoguide we start to add stiffnesses and materials.
In this videoguide we continue to add materials. Also we will learn how to assign stiffnesses and materials to finite elements. The algoritm of restraints setting is shown as well.
In this videoguide we will start to apply loads: dead weight, load cases, loads on bars.
In this videoguide we continue to apply loads: load case, ice load.
In this videoguide we continue to apply loads: load case, ice load, wind load.
In this videoguide we continue to apply wind load. First analysis of model. Results, displacements.
In this videoguide we apply wind pulse load. Also we will prepare model to analysis: Design combination of efforts (DCL table). Creation of foundation, subgrade moduli. Setting hinges. Analysis of the model: FEM analysis, design.
In this videoguide we analyze results. Displacements, check and selection of reinforcement and steel crosss sections. Tables, Report book.
