摘要

Abstract

[Significance]Engineering resilience relates to the ability of urban buildings,underground spaces,transportation infrastructure,historical buildings,and other engineering structures to withstand severe disasters,maintain their functions to the greatest extent during their entire service life,and recover quickly after a disaster.China experiences frequent earthquakes,and determining the seismic performance of engineering structures is crucial for improving seismic safety and serves as a fundamental basis for protecting human life,ensuring social and economic stability,and promoting sustainable development.[Progress]Shaking tables are one of the important experimental facilities used in seismic research.After more than half a century of development,China has made leapfrog progress in both the quantity and performance parameters of these systems.However,with the accelerated urbanization process and the increasing demand for a better life,complex and large-scale structures such as high-rise buildings,subway stations,urban diverging bridges,utility tunnels,large-span spatial structures,long-span bridges,nuclear power plants,and water conservancy projects continue to be constructed,posing greater challenges to engineering seismic research.As the political and cultural center of China,Beijing is located in a high-intensity seismic zone and is a key focus area for seismic monitoring and defense.The seismic safety of its infrastructure is particularly significant.However,existing large-scale structural dynamic laboratories around Beijing are mostly equipped with single shaking tables,and owing to limitations in table size and load capacity,they are unable to meet the experimental research requirements for large-scale,long-span,or other complex structures and infrastructures.Therefore,in active response to the strategic deployment of disaster prevention and mitigation by the CPC Central Committee,Beijing University of Civil Engineering and Architecture has completed the construction of a multi-functional shaking table system.This system aims to significantly elevate the modernization level of China's seismic research facilities,providing powerful technical support for the seismic design and operational management of major national projects.It simultaneously enhances the capabilities of fundamental research while achieving major technological breakthroughs in engineering resilience.The system comprises four triaxial,six-degrees-of-freedom,multi-functional,shaking tables,each measuring 5 m×5 m.These tables can be moved to any position on the rails and can be operated independently or in combination as a multi-table array system(in pairs,triplets,or all four).The system is capable of conducting single-table or multi-table vibration tests and can accommodate large-scale model tests with a maximum combined table size of 19 m×30 m.[Conclusions and Prospects]This system features the largest total payload capacity and able area among all existing four-table array systems worldwide,with technical parameters that reflect the latest advancements in the field.To simultaneously enhance the management level and operational skills of laboratory technicians and expand the scope and depth of shaking tables and how they assist society,the Multi-functional Shaking Tables Laboratory of Beijing University of Civil Engineering and Architecture actively promotes inter-departmental collaboration and information sharing.The laboratory also focuses on optimizing management mechanisms and gradually establishes a full life-cycle open-sharing management system.To date,these high-performance multi-functional shaking tables have successfully completed approximately 20 seismic performance tests and shaking table model experiments.
