Modern infrastructure is expected to last, 50, 75, even 100 years or more. But longevity doesn’t happen by accident.
According to research and analysis on structural failures, for instance in marine industry, a substantial portion of failures resulted from poor design because operational concerns were not considered, structural elements were not fully evaluated, and calculating methods were not used correctly.
That’s where analysis software steps in, not as an optional enhancement, but as a foundational tool for resilient and future-ready structural design.
In this article, we explore how advanced structural verification and simulation tools, like those provided by SDC Verifier, are redefining the way engineers build for the next century.
How Does Analysis Software Reinforce Structural Design for Long-Term Durability?
Why Structural Design and Analysis Software is the Backbone of Modern Engineering?
While structural design often takes the spotlight, structural analysis is what ensures that design performs in the real world.
Whether you’re designing offshore platforms, cranes, bridges, or pressure vessels, the structure’s ability to handle fatigue, buckling, dynamic loads, and environmental conditions starts with accurate analysis.
Traditional hand-calculation methods often simplify boundary conditions and ignore multi-axial loading scenarios. Today’s software can simulate these with greater accuracy and less conservatism.
Why Structural Analysis Is Important in Structural Design?
Structural analysis isn’t just a step in the process, it defines the design. Here’s how:
1. Informed Geometry and Material Choices
Advanced simulation tools allow for:
- Optimization of geometry to reduce stress concentrations.
- Accurate material modeling under cyclic or non-linear loads.
- Better understanding of how a structure will degrade over time.
This means engineers can design leaner, stronger, and more efficient structures that still meet safety standards.
2. Verification Against Global Standards
With increasing globalization, projects must comply with multiple international standards. Structural design and analysis software like SDC Verifier come with a built-in library of standards including:
- Eurocode 3
- DNV-RP-C203
- ASME VIII
- API RP 2A
- FEM 1.001
By embedding these standards within structural design and analysis software, compliance becomes proactive. not reactive. Analysis software helps integrate those requirements from the start, rather than retrofitting them later.
3. Fatigue and Lifecycle Predictions
The risk of fatigue is especially critical in offshore and mechanical structures. Modern FEA fatigue analysis tools apply methods like:
- Rainflow counting for variable amplitude loading
- Miner’s Rule for cumulative damage
- Standard-based fatigue checks (e.g. DNV, Eurocode)
Building for a Century: Key Capabilities to Look for in Analysis Software
If the goal is to build structures that last many years, your analysis software must do more than solve equations, it should drive design insights. Here are the must-have capabilities:
Standard-Based Verification
Pre-defined and customizable checks based on global engineering standards ensure compliance and transparency from concept to validation.
Fatigue, Buckling, and Joint Checks
Built-in tools for beam member analysis, including axial force and bending moment interaction checks, slenderness limits, and lateral-torsional buckling evaluations.
Parametric Load Cases and Automation
Why manually input hundreds of load combinations? Look for software that can automate verification over multiple load scenarios and design iterations, critical for offshore, crane, and wind turbine projects.
Integration with FEA Platforms
SDC Verifier, for example, integrates directly with Ansys, Femap, and Simcenter 3D, making it easier to incorporate advanced verification without switching tools.
Real-World Application: Offshore Structure Design
Consider an offshore floating production unit designed to operate for 25 years in harsh North Sea conditions. Traditional FEA can provide stress distributions, but advanced analysis software adds real-world depth by:
- Applying wave and wind load combinations based on Eurocode and DNV
- Running fatigue life calculations over millions of cycles
- Checking buckling of stiffened plates in the hull structure
- Validating welds against fatigue using S-N curves
These insights shape design decisions at every level, from choosing materials to defining reinforcement strategies. Without these verifications, the structure may pass initial checks but fail under long-term loading.
The Role of SDC Verifier in Future-Proof Design
SDC Verifier’s analysis software offers a unique blend of:
