In the demanding world of structural engineering, click here for info precision is not just a goal; it is a necessity. Bentley Systems’ RAM Elements has emerged as a versatile solution for engineers who need to analyze and design structures ranging from simple beams to complex multi-story buildings. However, like any powerful finite element analysis (FEA) tool, its complexity often requires external expertise.
Whether you are a firm looking to hire a civil engineering expert or an engineer seeking help to troubleshoot a model, understanding the ecosystem of RAM Elements is the first step toward structural integrity and workflow efficiency.
The Evolution of RAM Elements: What You Need to Know
Before diving into hiring or troubleshooting, it is critical to understand what the software currently offers. The 2024 update (Version 24.0.3) introduced significant enhancements that directly impact how engineers should approach modeling . One of the most notable changes is the enhanced force calculation using node forces in wall modules. Previously, users reported integration errors when relying on shell stresses; the new update uses node forces instead, providing more reliable results for wall design.
Additionally, for engineers working in the ANZ region, RAM Elements now supports wind load definitions per AS/NZS 1170.2, eliminating the need for external tools for code-based load generation. The software has also expanded its analytical capabilities to include cable members in response spectrum and buckling analyses, making it a true general-purpose solver .
The software operates on a robust analysis engine built by Bentley, utilizing a Reverse Cuthill-McKee Ordering algorithm for bandwidth optimization. This allows it to handle sparse matrices efficiently, supporting Static Linear-Elastic, Static Nonlinear-Elastic, and Eigenvalue analyses .
Core Challenges: When You Need Expert Help
Even with updated software, engineers frequently encounter technical roadblocks. Data from user forums highlight three common scenarios where hiring an expert or seeking consultation becomes necessary.
1. The Shear Wall Force Couple Problem
One of the most discussed issues in the RAM Elements community involves force distribution from concrete slabs into intersecting shear walls (e.g., elevator shafts or stairwells). Users often report a “very large force couple” causing walls to fail unrealistically .
- The Expert Solution: A seasoned civil engineering expert understands that when walls intersect to form complex 3D groups, a flange may go into tension while the web is in compression. An expert can diagnose whether the issue requires manual meshing, node fixing, or a separation of the walls into distinct nodes to resolve the stress concentration that the automatic solver misinterprets .
2. Shell Connectivity and Material Assignment
A common error message when transitioning models from RAM Structural System (RSS) to RAM Elements is: “Shells are not connected. Check shells connectivity” .
- The Expert Solution: This often occurs when modeling masonry or tilt-up walls. Experts know that the selected shells must comprise a single, connected 2D rectangle and must be assigned a specific material type (e.g., “Clay Masonry” rather than “Other”). Furthermore, they understand how to navigate the nuances of the material properties dialog—such as inputting irrelevant steel reinforcement properties for unreinforced masonry—to trick the module into running a valid analysis .
3. Advanced Module Integration
RAM Elements is not just an analyzer; it is a hub for design modules including Concrete Beam detailing, Footing design, and Masonry walls . However, transferring data between the main program and these modules is finicky.
- The Expert Requirement: To design a continuous beam, go to this site the selection order in the main program matters. An expert knows that beams must be in a continuous line (physical members) and that the program will reject models with alternate members selected. For footings, an expert ensures local axes of columns are aligned before invoking the combined footing module .
Hiring a Civil Engineering Expert for RAM Elements
When looking to hire, job postings reveal that proficiency in RAM Elements is often grouped with other Bentley products like STAAD, RAM Concept, and RAM Structural System .
What to look for in a candidate:
- Educational Background: A B.S. in Civil/Structural Engineering is standard, though an M.S. is preferred for complex FEA work .
- Licensing: An Engineer-in-Training (EIT) or Professional Engineer (PE) license indicates a foundational understanding of the physical laws governing the software’s calculations .
- Technical Stack: Beyond RAM Elements, look for familiarity with Revit for BIM integration and other analysis tools like ETABS or RISA .
Scope of Work:
Experts hired for RAM Elements typically handle:
- Model Auditing: Reviewing existing models for connectivity errors or unrealistic force couples .
- Code Compliance: Ensuring wind and seismic loads are applied according to the specific regional code (e.g., ASCE, IBC, or AS/NZS) .
- Optimization: Using the software’s optimization tools to reduce steel tonnage while maintaining safety factors, particularly in tapered members where unbraced lengths must be manually verified .
Training vs. Consultation
If your team lacks internal skills, you have two options.
- Formal Training: Institutions like YOV Academy offer structured courses (often in Spanish/English) on “Calculo y Diseño de Estructuras Metálicas con RAM ELEMENTS V8i”. These cover modeling, static/dynamic analysis, and report generation. Such courses are ideal for junior engineers who need to learn the interface from scratch .
- On-Demand Help: For urgent issues, the Bentley LEARN Server hosts live distance learning classes and community forums where experts provide specific fixes .
Conclusion
RAM Elements is a powerful ally in structural design, but its depth—ranging from node-force calculations to integrated masonry design—means that human expertise remains irreplaceable. Whether you are troubleshooting a failing shear wall in a high-rise or configuring a cold-formed steel platform, hiring a civil engineering expert who understands the software’s nuances (like the difference between shell stresses and node forces) is an investment in both safety and efficiency.
As the software evolves with 2024/2025 updates, the demand for engineers who can navigate its complexities will only grow. Ensure your team or your hires are not just familiar with the software, Visit This Link but fluent in its advanced analytical language.
