Loads and actions

8 modules
Load Factors
The module contains reference tables with load factors for weight of structures and soil as well as weight of equipment according to SNIP 2.01.07-85* Loads and Actions.


Dead Weight of Multi-layer Coating
The module for computation of normative and design loads from dead weight of the coat consisting of several layers. Resistance to heat transfer in multi-layer coat may be computed, if required.

Snow Loads
The module for computation of snow loads on buildings and structures.
• SNIP 2.01.07-85*. The program determines total snow load (normative and design values) on horizontal projection of roof slab according to table 3 Appendix 3.
• DBN V.1.2-2:2006. The program determines ultimate and service snow loads (design values) on horizontal projection of roof slab according to Appendix ZH.

Wind Loads
The module for computation of wind loads on buildings and structures.
• SNIP 2.01.07-85*. The program determines average component (normative and design values) of wind load. Aerodynamic coefficient is computed according to table 4 Appendix 4.
• DBN V.1.2-2:2006. The program determines ultimate and service wind loads (design values). Aerodynamic coefficient is computed according to Appendix I.

Ice Loads
The module for computation of ice loads.


• SNIP 2.01.07-85*. The program determines linear and surface ice loads (normative and design values).
• DBN V.1.2-2:2006. The program determines characteristic and design (ultimate and service) values of linear and surface ice loads.

Climatic Thermal Loads
The module for computation of climatic thermal loads on buildings and structures.
• SNIP 2.01.07-85*. The program determines normative and design values for variations of average temperatures, daily average temperatures of outer air, and initial temperature of completed structure.
• DBN V.1.2-2:2006. The program determines characteristic and design (ultimate and service) values for variations of average temperatures, daily average temperatures of outer air, and initial temperature of completed structure.
Data from Appendix 7 SNIP II-3-79** Heat Engineering for Construction Industry and Appendices 5, 6, 7 SNIP 2.01.01-82 Construction Climatology and Geophysics is considered in all cases.

Hazardous Energy Combinations of Forces (EnergyCF)
The module enables you to determine hazardous combinations of forces in bar sections according to criterion of extreme energy in the section for plane eccentric tension-compression.

Resonance Check for Wind Turbulence
The module enables you to check buildings and structures for resonance wind turbulence according to SP 20.13330.2011 and DBN V.1.2-2:201X. The program determines critical wind speed and intensity of resonance wind turbulence according to specified frequencies of natural vibrations.
