Purpose This paper aims to optimize cable-stayed force in asymmetric one-tower bridge formation using an improved particle swarm algorithm. It compares results with the traditional unconstrained minimum bending energy method. Design/methodology/approach proposes algorithm formation. formulates a quadratic programming mathematical model considering sum of energies main girder and tower as objective function. Constraints include displacements, stresses, force, uniformity. The is applied...
Purpose This paper aims to update the finite element model of a pre-stressed concrete continuous girder bridge using back propagation neural network optimized by improved mind evolutionary algorithm (IMEA). Design/methodology/approach In this paper, we introduce particle swarm optimization in convergence process (MEA) and then dynamically adjust inertia weights moving speed through nonlinear decreasing strategy, which is used solve drawback algorithm’s arbitrarily initialized population....
Purpose In order to unravel the evolution of microstructure characteristics and change mechanical properties bituminous mixture in freezing thawing environment cold region, this study starts from macroscopic experiments analyzes changes asphalt mixtures before after detail. On basis, displacement key particles structure under action external forces (before thawing) is simulated through combination microscopic methods. Design/methodology/approach The climate China exhibits high complexity...
Purpose In order to explore the damage probability of bridge engineering in event earthquake construction stages, analysis method seismic vulnerability stages is proposed this paper. Design/methodology/approach Based on joint simulation function stage conditions and response MIDAS/Civil finite element software, combined with IDA compared relationship between demand capacity. Findings The research shows that: (1) average loss different varies greatly; (2) greatly stages. 6 determined by...
The purpose of this study is to compare the mechanical properties continuous and discontinuous paving base mixtures. Two groups different types mixtures upper lower layers are designed. forming methods used for each type simulate construction process double layer paving. Then, unconfined compressive strength, splitting shear strength flexural tensile were tested under two curing periods (7 30 days) three test temperatures (room temperature, low temperature freeze–thaw). According results, it...
The design parameters are one of the important factors to ensure quality asphalt pavement design. In “Highway Asphalt Pavement Design Specification” (JTGD50-2017), stander China, used mixture anti-pressure resilience modulus at a single temperature 20 ℃ as metrics. However, mixture, sticky-bullet plastic material, shows different mechanical properties temperatures. China is vast territory, and there great differences between high low value (m n) each region. Therefore, it unreasonable only...
