Abstract Fire pose more severe threat to steel truss bridge girders as compared common plate and box girders. To deeply clarify failure mechanism of fire exposed girders, this paper presents an investigation on performance composite simultaneously subjected structural loadings hydrocarbon fires. A numerical model, developed using the computer program ANSYS, is validated dependent test trace behavior a typical through-type under different exposure conditions. The analysis applied evaluate...
Double-layer steel truss continuous girders are prone to significant temperature stress, deviation, torsion, and warping, thus causing adverse structural responses, also affecting the safety durability of bridge structures. This paper presents an investigation on time-dependent characteristics in field response double-layer girders, fully considering shielding effect subjected different solar radiation angles during high-temperature season. The thermal boundary conditions support provided...
Abstract Sequence identification and division is an important basis for oil gas exploration research. In view of the complex sedimentary environment, based on previous element logging correction lithology, through combination curve lithology data, in this paper, two methods maximum entropy spectrum analysis wavelet transform are used to identify divide interface, high-resolution sequence migmatite study area was completed. Compared with AC SP curves, overall local trend inflection points...
Abstract Clustered group nail connectors are key connecting components for the full lifecycle construction and safe operation of steel–concrete composite structural bridges. To thoroughly investigate stress mechanism clustered in structures, this paper conducts a detailed numerical analysis on 100 sets such connectors. It analyzes individual quantitatively calculates effect under coupled action multiple factors (nail spacing between layers, number concrete strength). Based clarifying force...
Ultra-high performance fiber reinforced cementitious (UHPFRC) and composite reinforcement techniques have great potential in achieving efficient structural resistance recovery overall enhancement. The goal of this study is to confirm the effectiveness by conducting test analytical studies for three full-scale prestressed concrete hollow slab girders with insufficient bending capacity stiffness. In study, four-point loading was adopted one before acquire residual performance. Reinforcement...
Curved continuous steel box girders are extensively utilized in bridge construction due to their efficiency and environmental benefits. However, regions with significant temperature fluctuations, effects can result cumulative deformation stress concentration, which may severely impact structural safety durability. This study examines the response of curved five spans under diverse conditions also develops a comprehensive parameterized thermodynamic numerical model. The model assesses...
