A framework is presented for predicting the dynamic response of long suspension bridges to high winds and running trains. three-dimensional finite-element model used represent a bridge. Wind forces acting on bridge, including both buffeting self-excited forces, are generated in time domain using fast spectral representation method measured aerodynamic coefficients flutter derivatives. Each 4-axle vehicle train modeled by 27-degrees-of-freedom system. The interaction between bridge realized...
Earthquakes in coastal areas frequently trigger tsunami waves, posing significant threats to low-lying bridges. Investigating extreme wave force on bridge deck is crucial for understanding damage mechanisms. However, the majority of current research focuses single deck, with limited analysis impacts twin decks. In this paper, solitary utilized simulate wave, and a two-dimensional (2D) computational fluid dynamics (CFDs) model analyze wave–bridge interactions investigate impact adjacent...
In the domain of bridge I-beam joint construction, conventional approaches such as cast-in-place concrete with suspended formwork and ordinary reinforced precast slabs entail numerous limitations. The former features complex procedures, elevated costs, significant safety risks, while latter is hindered by heavy weight slabs, which causes difficulties in transportation hoisting, inconvenient installation, high costs. Reactive powder ultra-thin slab (RPCUPS) regarded a potential solution due...
The effects of sample thickness on the density, microstructures and mechanical properties as cast Al alloy were investigated. Microstructures observed with a scanning electron microscope. Mechanical studied at room temperature. results show that has minor influence relative density alloy. obtained up to ∼99·24% was confirmed vacuum counter–pressure casting excellent solidification mechanism. refined secondary dendrite arm spacing decreased decrease in thickness, ultimate tensile strength,...
Steel-concrete composite beam cable-stayed bridge is a complicated system consisting of beam, tower, and stayed cables. And the composed steel deck connectors, which has different mechanical behavior from general structure. In word, steel-concrete characterized by specific many influencing factors. Thus, its safety analysis often cannot be easily implemented. This paper aims to study component reliability based on stochastic finite element method (SFEM) recognition main failure modes in...
In the process of continuous construction and development urban underground space, study influences adjacent on existing structures rail transit protection has become one most important issues sustainable development. Excavation foundation pit is common case, which, in built-up areas, can easily cause disasters, such as soil slip, failure foundation, pile deflection, uplift, etc., thus a great threat to safety surrounding buildings. this paper, we have collected large number examples...
The failure of the support system is one primary reasons for bridge failures during construction. Existing research on primarily focused falsework, with less attention given to other components such as Bailey beams, transverse and steel pipe piles. This study an incident where a cast-in-situ box girder experienced settlement due To thoroughly analyze accident's causes, multiscale elastic–plastic finite-element model was developed based actual on-site layout. By combining results...
In bridge construction, geometry control is critical to ensure that the final constructed has consistent shape as design. A common method by predicting deflections of during each construction phase through associated finite element models. Therefore, cambers different phases can be determined beforehand. These models are mostly based on design drawings and nominal material properties. However, accuracy these large due significant uncertainties actual properties materials used in...
It is of great significance to timely and accurately forecast the safety state bridge as far maintenance concerned. Bayesian forecasting a method deriving posterior distribution in accord with sampling information prior information, where real time online realized by means recursive algorithm stationary assumption. dynamic linear model created reliability on basis observed stress structure. According superposition constant mean seasonal effect model. The analysis practical example...
