What is being assessed?
Drawings, CAD, dimensions, supports, interfaces, known constraints and relevant simplifications.
Services
Bridge, Infrastructure & Strengthening
Advanced finite element assessment of bridges, masonry systems and infrastructure under extreme loading, local damage and strengthening or retrofit scenarios.
Buyer problem
Bridges · masonry · strengthening · resilience · extreme loads
Existing infrastructure often combines complex geometry, uncertain materials, nonlinear damage mechanisms and retrofit decisions that cannot be represented credibly by a single global stiffness model.
Method
High-fidelity structural modelling can incorporate nonlinear masonry/concrete behaviour, contact, dynamic loading, material damage and explicit strengthening layers or reinforcement to compare baseline and retrofit response.
Deliverable
Damage patterns, deformation, critical response histories, strengthening comparison, vulnerable-zone interpretation, model assumptions and technical reporting.
Value
The analysis helps teams identify failure mechanisms, understand retrofit effectiveness and prioritize the structural regions that deserve intervention or further investigation.
Typical inputs
What we need to scope this service.
Materials & loading
What controls the physics?
Material grade/data, preload or operating state, load history, pressure, temperature, impact/blast scenario or other relevant actions.
Decision objective
What must the analysis answer?
Local demand, failure mechanism, comparison, screening, residual response, retrofit effect, integrity concern or report requirement.
Technical depth
How Axis scopes the analysis.
01
When this service is needed
Use this service for bridge or infrastructure systems where local damage, material nonlinearity, extreme loading, strengthening concepts or unusual geometry make simplified assessment insufficient.
02
Modelling depth
Modelling may include detailed masonry/concrete behaviour, contact, dynamic response, material damage, CFRP/reinforcement representation, local geometric detail and comparative baseline-versus-retrofit studies.
03
Verification controls
Mesh sensitivity, material assumptions, load application, boundary conditions, energy/time histories for dynamic problems, and qualitative consistency with expected failure modes are reviewed.
04
Client value
Clients receive comparative evidence showing not only whether response changes, but where and why a strengthening concept alters the failure mechanism.
Typical inputs
- Geometry, survey/CAD information and structural details
- Material characterization or agreed constitutive assumptions
- Existing damage/condition information where relevant
- Loading scenario and strengthening concept
- Decision objective: vulnerability, retrofit comparison, damage mechanism or report
Scoping principle: the modelling level is selected after reviewing the engineering question, available data, uncertainty, and required decision. Axis does not recommend high-complexity simulation when a simpler verified check is more appropriate.
