Understand static behavior through deflection profiles

For each synchronized measurement timestamp, the tool converts tiltmeter data into a static deflection profile (y = f(x)) along the span, reconstructing the vertical displacement curve between the fixed endpoints. Profiles are computed relative to a baseline (zeroing timestamp), so each curve represents displacement compared to the selected reference condition.

The tool automatically stores and overlays multiple profiles from the same sensor group, enabling direct comparison across loading phases and test campaigns. Use overlays to assess repeatability, identify asymmetries, and detect potential changes in stiffness or boundary conditions through variations in curvature, peak location, and overall shape.

In addition to full profiles, the tool extracts maximum displacement (Ymax) from each curve and plots a maximum displacement trend over the selected load test.

This output provides a compact view of peak deflection over time, useful to validate load-step consistency, compare different testing days, and highlight residual deflection after unloading. You can track how peak displacement evolves across hours, days, weeks, or separate campaigns, while keeping the underlying profiles available for detailed shape inspection.

Create a tiltmeter sensor group once by defining span length, sensor order, and sensor positions along the structure. Then start a new static load test by selecting a zeroing timestamp that represents the baseline (typically an unloaded condition) and assigning a test name.

Each zeroing defines a dedicated load-test context: profiles and peak values are calculated against that baseline, keeping results organized and comparable even when tests are months apart or when sensors are temporarily redeployed on another span.
