Detect Cracks Early, Prevent Failures, Prolong Asset Life
Aging steel bridges under heavy rail traffic accumulate fatigue from millions of load cycles. Our Fatigue & Residual Life Assessment uses detailed FEM and fracture-mechanics models to predict crack growth, estimate remaining service life, and deliver prioritized recommendations for strengthening, retrofitting, or replacement.
Overview
At Sentra, we help bridge owners and operators evaluate fatigue behavior and remaining service life under cyclic loads. Using advanced FEM, crack growth models, and field data, we deliver clear insights and actionable strategies—whether strengthening, retrofitting, or replacement—to reduce risk, extend service life, and optimize costs. Whether you need short-term construction monitoring or permanent asset surveillance, our solutions scale from single-structure deployments to city-wide sensor networks.

Got Questions? We've Got Answers.
We provide end-to-end fatigue services: baseline fatigue surveys, targeted strain & vibration instrumentation, continuous data acquisition with edge preprocessing, cycle counting and rainflow stress-life analysis, crack detection & growth monitoring, probabilistic residual-life (RUL) modelling, and risk-based maintenance planning with CMMS integrations.
You’ll see early anomaly detections and short-term alerts within days of commissioning. A meaningful residual-life or RUL estimate typically requires 2–8 weeks of site-specific loading data plus an initial survey; pilot installs and targeted short-term campaigns can shorten that to 1–4 weeks for preliminary recommendations.
Yes. We design scalable SHM solutions for single-span bridges up to large multi-site railway networks. Small projects can start with a targeted pilot; large asset owners receive enterprise-grade deployments with multi-site dashboards, role-based access, and integration options. Solutions are tailored to budget, regulatory needs, and technical resources.
Clients retain full ownership of both raw and processed monitoring data. We act as a data processor and enforce industry best practices: encryption in transit and at rest, role-based access controls, SSO/SAML support, detailed audit logs, and configurable retention/backup policies. Third-party sharing or analytics is done only with client consent and can be governed by contract/NDA terms.
We recommend a hybrid approach: continuous monitoring for fatigue-critical, high-cycle or safety-critical assets, plus periodic physical inspections for verification. Typical cadence: critical assets — continuous monitoring + automated alerts with monthly engineering reviews and annual field inspections; medium risk — campaign monitoring or continuous with quarterly reviews; low risk — scheduled inspections (quarterly/biannual) with short-term monitoring during high-load periods. Final cadence is set after a rapid risk/prioritization survey.
Yes — every engagement includes a handover pack (SOPs, calibration logs, data formats), onboarding workshops, operator & admin training (onsite or remote), and training videos. We offer post-deployment support and maintenance tiers (hypercare, ongoing monitoring, software updates, remote diagnostics, periodic health checks and calibration support) that can be tailored with SLAs and spare-parts agreements.
