Weather Measurements During the CFS10 (10-Story Cold-Formed Steel Framed Building) Shake Table Test Program, in CFS10: 10-story Cold-Formed Steel Building Shake Table Program

A ten-story cold-formed steel (CFS) framed (CFS) building, herein referred to as CFS10, underwent seismic and post-seismic live fire testing at the 6-Degree-of-Freedom Large High-Performance Outdoor Shake Table (LHPOST6) facility at the University of California San Diego. Construction of the CFS10 specimen spanned from September 2024 to March 2025 and involved assembly using three different methods, namely: conventional stick-framing, two-dimensional (2D) prefabricated panels, and three-dimensional (3D) volumetric modular units. CFS10 was then outfitted with more than 1000 sensors (April - June 2025) and subjected to earthquake testing during a span of two weeks (June 2025), with motions reaching up to MCER-scaled events. Subsequently, the specimen was subjected to two post-earthquake live fire tests within distinct seismically damaged compartments (July 2025). This report summarizes the collection of three weather data streams (Elliott Station, Unit 1, Unit 2) located at or near the LHPOST6 facility, including one strategically positioned atop the 10-story building. Major events during the CFS10 program, notably construction, seismic and fire testing, are identified and correlated with the collected wind speed, wind direction, temperature, and relative humidity. Weather data is particularly valuable for correlation with ambient vibration measurements used to evaluate the structure’s dynamic characteristics. The dataset also documents the direct influence of environmental conditions on construction and testing operations; for example, the Level 6 module lift was postponed when wind speeds reached 20 mph, demonstrating direct operational dependence on real time data. Strong agreement among the Elliott Station, Unit 1, and Unit 2 sensors, evidenced by average temperature differences of 2–4 °F and closely aligned wind direction trends, confirms the reliability of the data streams and supports their use in future system identification and structural performance studies of this landmark building test specimen. It is noted that digital CSV data files from each of the sensors, for all timelines available, are archived with the present report.
