THP—Structure

Harmonic Coherence for Civil & Industrial Structures

One number. The complete health of any structure — from a cable-stayed bridge to an offshore wind turbine. THP-Structure monitors vibration, structural integrity, and load coherence in real time, flagging drift before it becomes failure.

Overview
THP-Structure — Structural Health Coherence
Structural coherence — measured in real time.
⬡
THP-Structure is built on the H-Space³ framework — a theoretical discovery establishing that structural health can be quantified through harmonic coherence, indexed by the golden ratio φ = 1.6180339887.

Six structural archetypes

01 · BRIDGE
Cable-Stayed Bridge
Symmetric strain monitoring across main spans. Damping ratio tracking, wind-induced vibration, traffic load coherence, and fatigue accumulation via Miner's Rule.

Critical Application

Offshore Wind —
Campbell Diagram monitoring

The margin between
1P and 3P is everything.

Every offshore wind turbine operates in a frequency window — the tower's natural frequency must sit between the rotor rotation frequency (1P) and three times that frequency (3P). This is the Campbell Diagram constraint. Violate it and the structure resonates. With resonance comes fatigue. With fatigue comes collapse.

As a tower ages, its natural frequency falls — steel corrodes, welds fatigue, grout in the monopile connection loosens. The gap between the natural frequency and the 1P lower bound narrows. When it closes, the tower is in resonance with its own rotor.

THP-Structure monitors this margin continuously. The resonanceCoherence axis within Vibration Coherence tracks the gap in real time. When the margin begins to shrink — weeks or months before any displacement measurement detects anything — THP starts falling and insights fire.

THP Classification

Five structural regimes

THP ≥ 0.90
Full Coherence
Structure operating at or near commissioning state. All axes within design envelope.
0.75 – 0.89
Stable Operation
Normal aging trajectory. Coherence preserved. No immediate intervention required.
0.60 – 0.74
Coherence Drift
Early degradation signal. Monitor closely. Schedule inspection window.
0.45 – 0.59
Maintenance Alert
Structural coherence compromised. Maintenance required before further loading.
THP < 0.45
Critical State
Harmonic collapse. Immediate structural review. Cease loading until assessed.
Core Modules

Everything in one app

01 · LIVE MONITOR
Real-Time THP Dashboard
Three coherence gauges — Vibration, Structural, Load — update continuously from the UDP stream. Animated collapse chart tracks the last 500 readings. Structural insights fire automatically when any axis drifts.
02 · GRACE STATE
Commissioning State Memory
THP-Structure learns the structure's commissioning THP and tracks every future reading against it. Coherence Loss is not an abstract threshold — it's measured against what this specific structure has already demonstrated it can achieve.
03 · REMAINING LIFE
Service Life Projection
Linear regression on the THP trajectory projects time to maintenance threshold (THP = 0.60). Confidence adjusts with reading count — low with 10 readings, high with 1095. The more you monitor, the more precise the forecast.
04 · IMPORT DATA
Smart Paste & CSV Analysis
Paste or drop any CSV/JSON sensor dataset. Automatic column detection by field name — works with any sensor brand or format. Analyse 3 years of historical data in seconds. Drop the bridge_3years.csv and see the trajectory immediately.
05 · EXPORT
Results to Clipboard
Export analysis results as CSV to clipboard with one tap — THP, vibration, structural, load coherence, regime, fatigue %, remaining life, limiting axis, and timestamp. Paste directly into Excel, Numbers, or Python.
06 · HISTORY
Session Reading Log
Every reading from the current session is logged with THP, regime, limiting axis, and fatigue. Export full session history as CSV. Compare sessions across inspection visits. Track fatigue accumulation over operational years.
