Abstract Throughout the ages, earthquakes have caused numerous instability and destruction of buildings. With increasing height volume modern buildings, seismic force on buildings gradually increases. To avoid serious damage ensure safety, design has become a crucial element in analysis structure. In traditional design, stiffness building is usually adopted to reduce structural response during ...

This paper focuses on the large-scale experimental investigation of a novel, highly efficient, low-cost and easily constructible seismic isolation system, defined as PVC-Rollers Sandwich (PVC-RS) isolation. The proposed system is based placement spherical roller bearings between two PVC surfaces in sandwich configuration. configuration triggers desirable rolling behaviour rollers surfaces, thus...

Due to the unique locomotion, head-shaking problem of biomimetic robotic fish inevitably occurs during rectilinear which strongly hinders its practical applications. In this paper, we experimentally study by proposing method coordination control between caudal fin and anal fin. First, an untethered fish, equipped with fin, a two pectoral fins, is developed as experimental platform. Second, Cent...

The Faraday resonance of interfacial waves in a two-layer, weakly-viscous system in a rectangular domain is presented. A perturbation analysis is pursued and, at the second-order, the scaling of the viscosity results in boundary layer corrections at the solid walls and at the interface. Special attention is paid to the damping in the meniscus region where the interface contacts the side-walls. ...

Ubiquitous smartphones have created a significant opportunity to form a low-cost wireless Citizen Sensor network and produce big data for monitoring structural integrity and safety under operational and extreme loads. Such data are particularly useful for rapid assessment of structural damage in a large urban setting after a major event such as an earthquake. This study explores the utilization...
