Analysis of steel structural elements

The application is to check elements and joints of steel structures for compliance with requirements of SNiP II-23-81* «Steel structures. Design regulations» and SP 53-101-96, SP 16.13330.2011, DBN B.2.6-163:2010. Besides, other state standards related to SNiP II-23-81* were implemented in the application, such as "Manual for designing steel structures (to SNiP II-23-81*) / Kucherenko Central Research Institute for Structural Constructions".

Capabilities

The following working modes are implemented in the application:

Steel quality - its principal task is to implement code's recommendations on choosing steel grades. Besides, reference information is displayed on compliance between steel quality of GOST 27771-88 and that of GOST or TU, and reference information on mechanical properties thereof can be also obtained.

Rolled steel assortment - it enables you to view assortments of rolled steel and obtain all sectional properties.

Bolts - this mode is used for viewing bolts assortment with indication of their class.

Limit slenderness values - this helps view recommendations of the selected code on assigning the limit slenderness.

Working conditions factor - this helps view and select values of working condition factors for elements in compliance with recommendations of SNiP, SP, DBN.

Envelope lines - this mode determines disadvantageous combinations of loads affecting flexural elements; envelope curves of moments and lateral forces can be obtained.

Geometry properties - all geometry properties are calculated for a cross-section (including sectorial moments of inertia).

Effective spans - this mode implements recommendations of Tables of SNiP and Eurocode-3. As a result, you can obtain values of effective span coefficients.

Section Resistance - this mode determines coefficients of limitation usage for any cross-section types of those implemented in the application under effect of arbitrary loads. Besides, interaction curves can be obtained for any allowable combinations of stress couples.

Bolted joints - coefficients of limitation usage for various structural concepts of bolted joints can be determined, and interaction curves for allowable combinations of stress couples can be built.

Friction joints - this mode is similar to the previous one, only it uses another set of structural concepts based on usage of high-strength bolt with controllable tension.

Welds - coefficients of limitation usage for various structural concepts of welded joints can be determined, and interaction curves for allowable combinations of stress couples can be built.

Local stability - local stability of webs and chord plates of flexural and compressed elements is verified; crane runway beams and beams with a web reinforced with longitudinal ribs are beyond consideration.

Truss elements - this mode implements all necessary verifications of truss elements for strength, stability and limit slenderness for structural designs most often used in practice. Rated stress values and combinations thereof caused by specified vertical external loads are determined. Cross-section selection is possible.

Beams - this mode is similar to the previous one, but this is oriented at analysis and design of I-shaped (welded or rolled) single-span beams with various supporting conditions.

Posts - this mode is similar to the previous one, this is oriented at analysis and design of columns and posts of various cross-section.

Base plates - this mode analyses plates which form a patand, under various conditions of rib bordering thereof.

Continuous beams - this mode is similar to the mode Beams.

Handy interface

The application works in the Windows Vista/7/8/10 operating environment. User dialogue techniques and controls conform completely to this environment.

Documenting your work

Calculation results can be represented as an illustrated report created automatically for you. The report can be then loaded into any Windows application associated with the RTF format (MS Word, for example).
