Which structural BIM software is developed by Bentley?

Bentley RAM is a structural building information modeling (BIM) software specifically developed by Bentley Systems. It focuses on structural analysis and design, providing comprehensive tools to support engineers and architects in creating safe, efficient, and cost-effective structures. The software offers advanced features for analysis, design, and documentation within the structural engineering domain. Its integration with other Bentley applications enhances collaboration and data consistency throughout the project's lifecycle, making it a vital part of the BIM ecosystem.

In contrast, the other options represent different software solutions not developed by Bentley. Tekla Structures is created by Trimble and is known for its strong capabilities in steel and concrete detailing. Trimble Pipe/Duct Designer 3D is also under Trimble's suite, focusing on MEP (Mechanical, Electrical, and Plumbing) design. Nemetschek ArchiCAD, developed by Nemetschek, is a BIM software primarily oriented toward architecture and building design rather than structural engineering. Thus, Bentley RAM stands out as the correct answer, as it is directly associated with Bentley Systems and specifically tailored for structural applications.
