    This dataset presents Structural Health Monitoring (SHM) data from the openLAB research bridge, a large-scale laboratory structure located in Bautzen, Germany. Following an initial one-year reference phase, the bridge will undergo a series of load tests designed to induce significant structural damage. This open-access dataset provides researchers with a rare opportunity to validate SHM methodologies under near-real-world conditions. The current publication includes data from the undamaged bridge, covering the period from 2024-02-01 to 2024-10-31. Additional repositories will be published periodically as new data becomes available. The bridge is equipped with a comprehensive monitoring system featuring fiber optic and electrical sensors that capture both structural behavior and environmental conditions (e.g., air temperature, humidity, and solar radiation). In this initial release, data is sourced from an electrical Gantner Instruments measurement system (Q.station 101T, with various Q.bloxx modules). The dataset includes measurements of acceleration, tilt, air temperature, humidity, and solar radiation. Data is recorded continuously at 10-minute intervals, with additional triggered measurements during non-damaging load tests conducted with a test vehicle or in response to increased vibration activity. The repository provides the data in Comma Separated Values (CSV) format. Each file includes a header specifying the names of the data columns. Additional details, such as units and sampling frequency, are provided in this README file. Each CSV file contains a Timestamp column that records the time of each sample as a datetime string in ISO 8601 format, without time zone information. All timestamps are in Coordinated Universal Time (UTC). Sensor data is represented as decimal numbers.
