LIRA-SAPR Lesson 2: Types of finite elements
In this video guide we will learn main finite elements, which are used in analysis in program Lira-SAPR.

LIRA-SAPR Lesson 1: The program interface. A beam on two supports.
In this video guide, we will learn the interface of the program LIRA-SAPR, and also perform the calculation of the beam on two supports with a uniformly distributed load.

Fire Resistance
LIRA-SAPR program makes selection and check of the reinforcement according to reduced parameters of concrete and reinforcement during the specified time period when the fire load is applied.
