Structural dynamic response corrupts frequently due to the sensor malfunction. The loss of will hinder structural condition assessment. In recent years, significant efforts have been devoted recovering during linear elastic stage structure. However, relevant researches on recovery damaged structures are rarely reported its strong nonlinearity. With growing significance post-disaster maintenance, it is critical develop effective methods for missing data in structures. To this end, paper...
Deflection data provides important information about the mechanical characteristics and structural health condition of bridges. The study presented here pertains to development a deep learning based approach for monitoring by employing bridge deflections. method herein uses long short-term memory (LSTM) framework in detecting state damage tracking feature changes time-series deflection temperature data. Chongqing Egongyan Rail Transit Suspension Bridge was employed over period 15 months...
Plate end (PE) debonding and intermediate crack (IC) are the two main failure modes of beams strengthened with fiber-reinforced polymer (FRP) in flexure. Therefore, it is essential to clarify force state structure when occurs beams. This paper collected 229 as database, which 128 were PE 101 IC debonding. Correlation grey correlation analysis used establish indicator systems for predicting identify critical indicators among them. Five machine learning models, linear regression, ridge...
This paper presents a non-destructive test method for steel corrosion in reinforced concrete bridges by using 3-dimensional digital micro-magnetic sensor to detect and analyze the self-magnetic field leakage from corroded concrete. The setup of magnetic scanning device measurement mode are introduced. numerical analysis model is also built based on linear charge theory. Compared data obtained sensor-based calculation, it shown that curves tangential at different lift-off height all intersect...
Bridges are an essential part of the ground transportation system. Health monitoring is fundamentally important for safety and service life bridges. A large amount structural information obtained from various sensors using sensing technology, data processing has become a challenging issue. To improve prediction accuracy bridge structure deformation based on mining to accurately evaluate time-varying characteristics performance evolution, this paper proposes new method prediction, which...
To accurately evaluate the overall corrosion degree of reinforced concrete (RC) beams, on basis SMFL technology, random detection experiment six RC beams was carried out. The relationship between tangential component By and normal Bz magnetic induction intensity analyzed, a multidefect dipole model established. correlation average ratio C beam characteristic index KG emphatically explored. results showed that, with increase in C, an increasing trend as whole. could weaken influence different...
The fatigue problem of orthotropic steel bridge decks urban rail transit bridges has gradually become one the hot research topics. And it is also a key that restricts further development bridges. In this paper, deck structure long-span cable-stayed studied. Based on segmental finite element model and full-scale model, details joint weld between an U-rib were studied theoretically experimentally. theoretical segment analyzed to obtain spot stress characteristics. On basis, test performance...
