Our vision/mission is to support the research and development of transformative earthquake hazard mitigation strategies by providing the research community with a state-of-the-art facility capable of performing large-scale testing with realistic seismic loading.

Standard experimental protocols for the LHPOST6 have been developed to ensure that all technical program objectives are met on time and on budget, and that the project will be successfully and safely completed. The LHPOST6 builds on 10 years of very successful test programs for many government agencies and commercial businesses following these protocols. At the beginning of a test program, the research team, which includes the sponsor or user, PI, Co-PIs, students, and facility staff and Co-PIs responsible for Safety and Instrumentation, as applicable, meets to discuss the test objectives, the test and safety plan and the test schedule. Based on past experiences, appropriate suggestions are made to ensure that the test plan is compliant with the schedule and budget, and that Cal/OSHA requirements are met to satisfaction.

The LHPOST6 is the largest shake table facility in the U.S. and the second largest in the world. It enables ground-breaking experimental research related to structural, geo-structural, soil-foundation-structural, and non-structural components and systems including how these systems behave during realistic multi-component earthquake excitations, and how they should be conceived and designed to resist such excitations best.

The LHPOST became the first known large-scale structural testing laboratory in the United States to demonstrate compliance with the International Standards Organization ISO/IEC 17025.

Testing on the LHPOST6 can provide crucial data for developing and validating high fidelity computational models and decision-making design tools necessary to build and maintain sustainable and disaster-resilient communities. The data acquired from such landmark tests will enable calibration, validation, and improvement of (mechanics-based, physics-based) analytical and numerical models able to capture the seismic response behavior of civil infrastructure systems, accounting for these realistic and important effects. Research outcomes will impact both new construction and retrofit of existing infrastructure.

To maintain a safe, productive, and compliant site, all external users are required to adhere to the facility's lab rules.
