A novel energy-dissipation system for frame-core tube structure equipped with damped outriggers is studied experimentally. A steel frame-core tube structure model is designed and manufactured, in which viscous dampers are inserted vertically between the outrigger and fame columns to make full use of motion discrepancy of these two components. Shaking table tests of the building with damped or f...

Abstract Large-span steel structures have been widely adopted in stadiums, airports, factories, and train stations because they provide a large space for multi-functional use. To ensure business continuity, post-earthquake damage surveys structural status estimation of such important large-spaced buildings attracted increasing attention. Structural health monitoring using accelerometers is alre...

With the continuous development of traffic construction, road engineering inevitably crosses aeolian sand river valley area. Compared with general sandy soil and silty soil, cohesionless foundation has similar properties fluid higher liquefaction potential. Precast cement pile can greatly improve vertical bearing capacity foundation, but this paper finds that it also antiliquefaction effect whe...
