On the chart below you will see how the work of the student may be organized. This process enables the users to minimize the time required to be spent in the classrom when using demo version & version distributed fee of charge together with Academic Set version.
Demo version of LIRA-SAPR contains SAPFIR Study version. Outside the classroom and without protection key, you could generate full design model (with specified loads applied as load cases, triangilation, etc.). Problem file generated in this version may be transferred to VISOR-SAPR system of version Academic Set, then you will add parametric tables (DCF/dynamics/collection of masses) and carry out analysis. Then you could take home the saved input data (design model in *.lir format) and output data (including export of selected reinforcement for SAPFIR-RCstructures), evaluate results in Demo version of LIRA-SAPR, and generate drawings of reinforcement in SAPFIR-RCstructures module in Study version. That is, at home you could evaluate data, prepare output data and generate drawings of RC structures and RC structure items. Thus, time necessary to be spent in the classroom of the institution is reduced to min.
In addition or instead of Demo version, you could use LIRA-SAPR 2013 R5* distributed free of charge. Data formats of these vesrions are compatible. That is, problems generated in 'LIRA-SAPR 2013 R5*/SAPFIR2015' may be opened in Demo version 'LIRA-SAPR 2017/SAPFIR 2017 Study version' and vice versa. But commercial version does not support these formats.
