National Soil-Foundation-Structure Interaction Laboratory (SoFSI)
University of BristolLangford, Bristol
The University of Bristol’s SoFSI laboratory at Langford Campus brings structural and geotechnical engineering together for soil–structure interaction research. Published equipment includes a large biaxial shaking table, a soil pit with pseudostatic and dynamic actuators, and a separate high-g multi-axis table. The owner welcomes academic, industry and facility-hire enquiries at uob-sofsi@bristol.ac.uk. Discuss the experiment, required loading and reporting directly, with no accredited testing scope inferred from the published equipment or provider BELLCORE capability statement.

Key facts
- Current facility and Langford location
- SoFSI is a University of Bristol soil–structure interaction laboratory at Langford Campus. The owner’s contact page gives Harptree Building, Langford, Bristol, BS40 5DU.
- Prototype and full-scale research
- The owner describes large prototype-scale experiments for academics and industry. UKCRIC lists research on bridge piers and abutments, foundations, retaining walls and embankments under static, vibration and earthquake-like loads.
- Separate test systems
- The owner lists a 6 m by 4 m biaxial shaking table, a 6 m by 5 m by 4 m deep pit with distinct actuators, and a separate high-g multi-axis simulation table. Each has its own published limits and configuration.
- Dedicated enquiry
- Contact uob-sofsi@bristol.ac.uk for further information, visits or working with the facility. The owner also invites facility-hire enquiries.
Testing capabilities
Large soil–structure interaction experiments
The owner’s pit, adjacent strong floors and actuators support soil–structure research at prototype scale. UKCRIC describes large to full-scale bridge, foundation, retaining-wall and embankment studies. Confirm the soil preparation, structure, boundary conditions, fixture and loading history for the experiment.
Biaxial structural dynamics and vibration
The 6 m by 4 m biaxial shaking table supports structural dynamics research and the static, vibration and earthquake-like loading applications described by UKCRIC. The owner states BELLCORE test capability, with the required procedure, payload, fixture and motion profile to confirm.
High-g multi-axis simulation
The owner lists a separate high-g multi-axis simulation table with an 800 kg capacity and peak acceleration greater than 10 g. Confirm the specimen, fixture, axis, frequency and acceleration history together. The published payload and acceleration maxima are not a guaranteed simultaneous operating point.
Equipment and published limits
| Specification | Published value | Conditions |
|---|---|---|
| Large biaxial shaking table | 6 m by 4 m. Capacity 50 tonnes, peak acceleration 2 g, maximum frequency 50 Hz | These are the separate figures on the owner’s equipment page. It does not establish that maximum payload, acceleration and frequency can be achieved together for every fixture or motion history. Its BELLCORE capability statement is qualified in standards. |
| Soil pit and distinct actuators | 6 m by 5 m, 4 m deep. Two 1 MN pseudostatic actuators with 1000 mm stroke, one 1 MN dynamic actuator with 500 mm stroke | The owner describes adjacent strong floors for mounting these actuators. Stroke is retained as published, without converting it to travel in each direction. No summed simultaneous load capacity or dynamic-frequency envelope is stated. |
| High-g multi-axis table | 800 kg capacity. Peak acceleration greater than 10 g | This is a separate simulation table. The owner does not give its dimensions, an upper acceleration bound or a guarantee at maximum payload. UKCRIC’s separate 1 m by 1 m, 10 g description is not merged into this current owner specification. |
Access and contact
Email uob-sofsi@bristol.ac.uk for facility information, visits, collaboration or hire enquiries, and describe the soil or structure, required test system, loading history, fixture and measurements. SoFSI is at Harptree Building, University of Bristol Langford Campus, Langford, Bristol BS40 5DU. The owner describes academic and industry prototype-scale research. UKCRIC separately invites early research-project enquiries at hello@ukcric.com, with visits, intellectual-property discussion and EPSRC-funded proposals given priority. Confirm availability, technical support, costs and reporting directly.

Standards and accreditation
- Provider-stated BELLCORE capability
- The owner describes the 6 m by 4 m biaxial table as capable of meeting BELLCORE test standards. The exact standard number, revision, test procedure and accredited scope are not specified. Confirm the required qualification profile, fixture, payload and reporting for the proposed work.
What to confirm with the facility
- The published BELLCORE statement is a provider equipment-capability claim, with no exact procedure or accredited testing scope verified. UKCRIC states that it is not a lab service provider or an accredited analysis service. Agree required standards and reporting for the proposed experiment.
- The large-table capacity, acceleration and frequency describe separate limits. The pit’s pseudostatic and dynamic actuator ratings are not a summed load guarantee. The high-g table’s payload and acceleration likewise require a confirmed combined operating envelope.
- UKCRIC lists a 1 m by 1 m, 10 g smaller-table description. The current owner describes an 800 kg multi-axis simulation table with acceleration greater than 10 g, without dimensions. Those source descriptions are kept separate until the required installation and configuration are confirmed.
- The research-capabilities page also refers to the wider Earthquake and Geotechnical Engineering Research Group. Wider university equipment and capabilities are not allocated to SoFSI without facility-specific evidence. The gantry crane is handling equipment rather than a test-load rating.
- Confirm soil and specimen preparation, installation and reaction design, fixture mass, motion and load history, measurement needs, responsibilities, costs, programme and report format directly.

Sources and review
Reviewed by Arc on 1 October 2026 using fresh official University of Bristol SoFSI identity, contact, equipment and research pages, with UKCRIC context. Equipment-page metadata records publication on 18 February 2021 and modification on 6 November 2025. Contact-page publication and modification metadata are dated 25 January 2022. Research-page metadata records 4 March and 25 June 2021 respectively. Homepage and network publication dates were not verified, and October 2021 showcase materials are separate event context. Current owner and network table descriptions remain separate, with no accredited scope or combined maximum-duty guarantee inferred.

SoFSI University of Bristol facility
The owner describes soil/structural research, invites facility-hire enquiries and gives uob-sofsi@bristol.ac.uk. Wider Earthquake and Geotechnical Research Group activity is not treated as installed SoFSI equipment.
The owner lists the large biaxial table, pit with separate pseudostatic and dynamic actuators, and high-g simulation table. Its BELLCORE statement is a provider capability claim. Metadata records publication on 18 February 2021 and modification on 6 November 2025, separate from this review.
The page gives the dedicated SoFSI enquiry route and Harptree Building at the University of Bristol’s Langford Campus, Langford, Bristol, BS40 5DU. Its publication and modification metadata both fall on 25 January 2022.
This page describes research within SoFSI and the wider research group. It is context for the laboratory’s purpose, without transferring all wider-group capabilities or equipment. Metadata records publication on 4 March 2021 and modification on 25 June 2021.
