This study evaluated the fatigue performance of rib-to-deck welded joints in orthotropic steel decks (OSDs) with thickened edge U-ribs (TEUs). Fatigue four specimens TEUs was investigated and compared those three conventional U-ribs. Overall, use enhanced strength joints. Finite-element modeling conducted validated by experimental data sensitivity analyses. The finite-element model then used to investigate mechanism for enhancement strengths caused evaluate effects weld penetration open...
In this paper, a three-dimensional nonlinear dynamic analysis framework for RC bridges is established based on the force analogy method (FAM). Two biaxial local plastic mechanisms, rotation hinge (RH) and slide (SH), are proposed fundamental concept of FAM to simulate flexure-shear interactive behavior piers, critical consideration seismic performance assessment bridges. The RHs located at ends piers express relationships moment versus rotation, whereas SHs assigned shear deformation...
An accurate modeling of roller bearing element, considering the complex contact behavior and load conditions, is very important to geared-rotor system design. This paper presents an enhanced stiffness matrix for a deep groove ball by including elastohydrodynamic lubrication (EHL) effects in ball-raceway contact. The model subjected coupled lateral-translational loads. EHL calculated employing multilevel method. Then, result was used drive relationship between force mutual approach. Moreover,...
The load-displacement relation for rolling element bearing is a system of nonlinear algebraic equations describing the relationship forces and displacements needed to compute stiffness. computed stiffness typically employed represent effect when modeling whole geared rotor optimize parameters minimize unwanted vibrations. In this study, robust numerical scheme called energy method developed applied solve from potential instead solving these using classical integration. proposed based on...
Abstract Metallurgically Clad Pipes (MCP) have a strong bond between the outer pipe and liner, effectively avoiding separation failure of Mechanically Lined (MLPs). The girth weld position in an MCP becomes weakest point entire pipeline. In this study, three-dimensional bimetallic model with is established, considering factors such as reinforcements, bottom width, groove angle, misalignment value, heat-affected zone material properties zone. influence different working internal pressures...
The intricate interplay between the microscopic constituents and their macroscopic properties for masonry structures complicates failure analysis modelling. A composite strategy incorporating neural network (NN) cellular automata (CA) is developed to predict load panels with without openings subjected lateral loadings. discretized are modelled by CA methodology using nine neighbour cells, which derive state values from geometric parameters opening location placement panels. An identification...
This paper introduce the basic overview of project Shenyang Metro Lishui City, trough isolation technology applied in we talk about concepts isolated structure,category and application. It describes structure performance comparison laminated rubber bearings.At last, briefly introduced problems to be solved structure.
The stress concentration factors (SCFs) is used in the fatigue design for calculating hot-spot stress. However a major issue can be noted that majority of research results are focused on SCF distribution uni-planar tubular joints subjected to single basic load. By aiming find solution this problem, SCFs at weld toe multi-planar DX-joint which two set balanced combined loading components end in-plane braces studied by finite element method. Thus it concluded axial plus bending load case,...
