Highway Sound Barrier Structural and Acoustic Calculator

Problem

Highway sound barrier reviews often mix two calculation domains: structural capacity and traffic-noise attenuation. Parameters such as basic_wind_pressure, terrain_category, and section_name affect column bending, stability, and deflection, while traffic_volume, truck_ratio, and receiver_distance determine whether receiver points meet target noise limits. Manual checks are easy to fragment, especially when comparing several schemes.

How It Works

The skill runs a fixed workflow: parameter validation, structural calculation, acoustic calculation, and Markdown report generation. It accepts parameters either interactively or from a CSV batch keyed by case_id. Structural checks cover wind load, column strength, overall stability, deflection, and connector checks, using built-in steel section, steel grade, and terrain roughness data. Acoustic checks estimate source level, insertion loss, and noise reduction performance from traffic volume, truck ratio, design speed, receiver distance/height, and target limit. The final report includes design assumptions, calculation steps, and conclusions.

Limits

It is suited to new-design verification, existing-barrier review, and scheme comparison. Outputs depend on complete, realistic inputs; unusual foundations, fatigue, seismic, frost, or local code differences should still be reviewed by a qualified engineer.
