The following prototype joints are available: column base, beam-to-column goints (pinned and fixed), beam splice, beam connection, column splice, sway bracing, rigid connections (beam-to-beam and beam-to-column). Prototype joint is a model for analysis; the model consists of several parameters that further in analysis procedure will be selected and checked according to SNIP II-23-81*.
Every analysis has its tracing routine that enables the user to review applied formulas and algorithms in symbol and numerical form.
Analysis of joints may be carried out in STC-SAPR module of LIRA-SAPR program and in ESPRI program as well. Prototype joint with selected and checked parameters may be imported to KM-SAPR module where 3D model of the joint and all necessary drawings will be generated.
In the latest versions of VISOR-SAPR it is possible to design compound joints from any number of simple ones. (Option is not available in ESPRI program.)
