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...
Focused on optimizing the vortex-induced vibration (VIV) of bridge towers, this study explores aerodynamic characteristics tandem rectangular cylinders with varying corner recess sizes through three-dimensional large eddy simulation. The effects forces, mean and fluctuating pressure distributions, flow structures, separation bubbles, Strouhal numbers are thoroughly analyzed using five numerical simulations. results reveal that key factor driving VIV in is significant lift experienced by...
This paper presents a novel robust sliding mode controller with fuzzy tuning for Stewart platform servo system, which suffers from high nonlinear dynamics and serious load coupling among channels. The consists of an equivalent control to assign desired the closed-loop switching guarantee mode, enhance fast tracking attenuate chattering. To verify potential effectiveness proposed controller, simulations experiments are made. results demonstrate its strong robustness against large range...
The conventional network structure measure, betweenness centrality (BC), has been used to predict roadway traffic flow; however, without consideration of variable travel demand on the network, measure’s prediction capability is limited by its static nature. With objective explicitly addressing effects pattern [e.g., origin–destination (O-D) distribution] urban flow, this paper proposes a modified measure that integrates BC index and traditional metrics (i.e., O-D ratios total demand). In...
This study addresses the effects of vertical motion on nonlinear flutter response a double-deck truss girder based section model wind tunnel tests. Six dynamic systems with same bridge deck were tested under various angles attack. The characteristics different cases fully captured. potential effect coupled was investigated by conducting an additional single-degree-of-freedom test. aeroelastic mechanism concerning that affects performance is revealed qualitatively estimating contribution...
The frequently conventional assumption that bridge temperature is uniformly distributed on long-span bridges could lead to uncertainty when analyzing effects. This study investigated the surface of steel box girders a suspension bridge, emphasizing distribution characteristics in longitudinal (spanwise) direction. girder was monitored using long-term structural health monitoring system (SHMS). First, probability density functions (PDF) were analyzed. results showed PDFs had bimodal and be...
With the high fuel prices, demands for energy saving and green emission of engineering machinery have been increased rapidly. Due to complex working condition frequent load changing, efficiency hydraulic excavator is low. The aim this article propose a control strategy recovery system driven by parallel hybrid system. mathematical models main components simulation proposed conventional are built. Then, according characteristic, based on state charge battery given. co-simulation established....
Road classification and hierarchy are the fundamental of road network planning design, a set strict quantitative method can reduce or even eliminate subjectivity uncertainty in urban planning. Based on summarizing deficiencies existing method, this paper focus structure importance with complex analysis techniques, building an index to describe comprehensive quantified method. The built here takes both characteristic width into account. Through case study Mianyang, we find that, some extent,...
