This paper presents a preliminary design approach for tuned particle dampers continuous viaducts. A series of shaking table tests 1/10-scale model bridge with and without was carried out to evaluate the performance system verify analysis method. An analytical energy method established simulate behavior damper using finite-element model. The experimental computational results show that proposed can be valuable tool in application damping controlling seismic response bridges. effectively...
Abstract Energy dissipation is an important method for improving the seismic performance of super high‐rise (SHR) structures. However, few quantitative studies have focused on new energy methods and their application in SHR structures, especially those under long‐period ground motion, including near‐fault pulse‐type (NFPT) motion. Thus, this study, a 1/20‐scale model typical structure was designed manufactured, various earthquake waves were selected based site condition structure, such as...
To improve the mechanical behaviour of traditional reinforcement concrete (RC) column, a novel prefabricated engineered cementitious composite (ECC)–reinforced (ECC shell–C) column was proposed in this study. Subsequently, five ECC shell–C columns, as well one cast–in–place (CIP) RC and CIP pure were designed manufactured. Then, axial compression tests carried out to explore their with considering effect shell thickness t stirrup ratio ρv. On basis, numerical analysis method for developed...
Near-fault pulse-type (NFPT) ground motion is characterized by pronounced velocity pulse effects. Its period typically greater than 1 s, and has a large influence on the seismic response of long-period bridges. However, few quantitative studies about parameters have been reported. In this work, that – namely, (VPP), amplitude (VPA), number (VPN) bridge was studied. A 1/15-scale model designed synthetic method introduced to obtain artificial NFPT motions. Then, series shaking table tests...
Fluid in the ship pipeline, due to power equipment components (such as impellers, plungers, etc.) and valves, will induce turbulence, cavitations, which generate high-frequency vibration excitation lines. The measurements results show that fluid-induced of pipeline is not only confined but also have an impact on hull structure. Pipe transient flow very common marine pipe system Thus fluid-structure interaction problems shipping lines being paid more attention. In this paper, fluid-filled...
The application of the particle damping technology in civil engineering is limited owing to complex nonlinear mechanical properties and lack a reasonable model. existing equivalent single-particle model cannot include interactions between particles. In addition, an appropriate determination parameters required. this study, consider influence particles, dual-mass (DMEM) proposed based on motion state analysis. A shaking table test single-story frame under harmonic excitation was carried out...
The dynamic characteristics of a continuous rigid-frame bridge with fabricated super-high piers (CRFB-FSP) connected by grouting sleeves and adjacent beam bridges (AB) are significantly different, they prone to pounding under earthquake excitation. At present, the response between CRFB-FSP AB is still unclear, impact on seismic performance in exploratory stage. In this study, two 1/20 scaled models (MB) cast-in-place were designed manufactured. Then, according research purpose output shaking...
Multi-particle dampers (M-PD) can be potentially applied in civil engineering because of their good damping effect and wide frequency band. However, complex nonlinear mechanical properties the lack a reasonable model, development application practical are limited. Therefore, without considering accumulation particles, an equivalent inertia single-particle model (EISM) is proposed by introducing inerter to consider particle rolling on mechanism performance. Dynamic analyses EISM single degree...
Curved high-pier rigid frame bridges (CHRF bridges) are unavoidably affected by near-fault ground motions (NFGMs), and seismic pounding between adjacent components of CHRF bridge has a significant effect on the performance bridges. The response laws under NFGMs need further investigation. In this study, influence with impulse directional effects dynamic was studied. Subsequently, responses were systematically analyzed. results showed that have impact impulse-like (IPGMs) is greater than...
