STEEL CALCULATOR™

The SAFI STEEL CALCULATOR™ allows to quickly verify, design and optimize steel beams and columns. It is also an efficient validation tool to verify design results of specific elements of complex models.

The SAFI STEEL CALCULATOR™ allows the user to verify and optimize single and continuous beams and columns. The use of the Steel Calculator does not necessitate the input of an analysis model (joints, members and combined loads). These operations are automated.

The SAFI STEEL CALCULATOR™ allows to verify or optimize any standard section available in the SAFI databases according to the Canadian S16 standards, the American LRFD and ASD standards and the European Eurocode 3 and the Indian IS 800.

It is an efficient validation tool to verify design results of specific elements of complex models. Design optimization and automatic section selection features make economic and quality steel structures a reality.

The SAFI STEEL CALCULATOR™ is used as a standalone application or in combination with the GSE STEEL DESIGN program, part of the GSE (General Structural Engineering) software.

The user can select an appropriate model from the numerous available ones provided with the SAFI STEEL CALCULATOR™ . The input data consist of selecting a section shape and defining the basic loads, the design parameters and the geometric limits.
The results of the Steel Calculator are summarized for each member and displayed on the screen, detailed reports are also available.

The Steel Calculator for continuous beams and columns can rapidly perform the computations to carry one of the following tasks:
– Verification of the limit states design. A summary and a full analysis and verification report are available.
– Optimization according to weight in an attempt to find the best section. A summary and a full analysis and verification report are available.
– All sections results, which is a table to present the behavior of the model for every section in the databases. The best section is indeed included in this table.

STEEL STANDARDS

The steel standards with which the verification and optimization calculations are made must be selected. The user must define the combined loads for verification and design computations. The combined loads are automatically generated when you use the Steel Calculator.
