Structural Engineering and Design (AEC)

Versatility and data integration drive productivity for building and non-building structures. Altair's Architecture, Engineering, and Construction (AEC) structural analysis and design solutions simulate responses to wind, snow, water, seismic, blast, dead, live, and moving loads, or other dynamic, nonlinear loading conditions while ensuring design resiliency and regional code compliance. Extensive data transfer links manage consecutive import and export cycles between analysis and design solutions, building information modeling (BIM) systems, and/or CAD platforms. Design and optimize concrete, steel, and timber to regional codes, generating report-ready results for all structural elements in a model.

Altair for AEC Structural Design

Optimize Your Design Projects with Integrated Solutions

Our integrated structural design solutions are tried and trusted by engineers worldwide to ensure code compliance, optimized designs, and reduced project times.

Altair® S-FRAME®

Allows users to simulate the response to internal and external forces during and after construction. Regardless of geometric complexity, material type, loading conditions, or nonlinear effects, S-FRAME analyzes structural behavior and generates reaction forces so engineers can optimize models while verifying compliance with regional design codes for steel, concrete, and/or multi-material structures.

Altair® S-STEEL™

A fully integrated steel design solution, S-STEEL provides transparent, comprehensive results for any steel design project. With it, users can code-check and auto-design for strength, serviceability, and compliance to regional design codes. S-STEEL supports composite beam design, staged construction, and numerous optimization criteria and constraints. Users save time by easily generating and exporting design results to customized engineering reports that include clause references, equations deployed, identifying passing or failing steel members.

Designing for Sustainability - Reducing the Carbon Footprint with Embedded Carbon for Large Scale, Hybrid Timber Structures

Bush Bohlman was required to perform the structural analysis and timber design for the British Columbia Institute of Technology, (BCIT), student plaza, a pedestrian and public transport user gateway for the institute. The structure needed to establish a strong campus identity with a biophilic design and demonstrable support for sustainable building practices while ensuring structural safety according to local design codes. The hybrid mass timber structure consists of a Cross-Laminated Timber (CLT) canopy, CLT columns, and steel columns. By using S-TIMBER, the engineers were able to simulate the complex two-way bending behavior of the cantilevering roof panels and asymmetrical column layout. Having the model in S-TIMBER allowed for changes to be analyzed and re-designed, without the need to manually design individual timber and steel elements. S-TIMBER's design reports presented the design calculations concisely, yet transparently, for faster and easier reviews.

Steel Design for Structural Engineers, CSA 16-14 Code Examples

The Steel Design Examples for Structural Engineers demonstrates thirty-three different steel design applications according to the CSA S16-14 steel design guide. This guide serves two purposes; to illustrate the CSA S16-14 steel design code and to enable users to verify S-STEEL's design accuracy.

Included with each example are example (.TEL) files that help illustrate the CSA S16-14 steel design code in S-FRAME/S-STEEL.

The CSA examples are adopted from a subset of the AISC’s publication Design Examples (version 14.2) with all examples converted to metric units.
