Long-Term Behavior of Timber–Concrete Composite Beams. II: Numerical Analysis and Simplified Evaluation
Publisher: American Society of Civil Engineers
Abstract: This second part of two companion papers investigates the contribution of different rheological phenomena and thermohygrometric variations on long-term behavior of timber–concrete composite beams (TCCs) in outdoor conditions. ...
Pressure Variations During Warm Hydrotesting
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. In the pressure vessels and heat exchanger manufacturing, some codes and specifications require the final acceptance test (hydrotest) to be performed at temperature higher than the ambient temperature. This may ...
Influence of the Construction Method on the Long-Term Behavior of Timber-Concrete Composite Beams
Publisher: American Society of Civil Engineers
Abstract: Timber-concrete composite beams (TCCs) are made from a concrete topping fastened to a timber beam. Different methods can be used to construct the TCCs. The concrete topping can be either poured on the timber beam with ...
Long-Term Behavior of Timber–Concrete Composite Beams. I: Finite Element Modeling and Validation
Publisher: American Society of Civil Engineers
Abstract: This first part of two companion papers deals with the numerical modeling of timber–concrete composite beams (TCCs) under long-term loading. All phenomena affecting the long-term behavior of timber, concrete, and the ...
Thermic Influence on the Dynamics of Pneumatic Servosystems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The gain values that can be imposed in pneumatic system controllers are bounded to the restricted actuator bandwidth. That limitation, with low damping and stiffness due to the air compressibility, ...
Computational Fluid Dynamics Analysis of Gerotor Lubricating Pumps at High Speed: Geometric Features Influencing the Filling Capability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper presents an extensive analysis of the influence on the suction capacity of the main geometric parameters of gerotor lubricating pumps. The study was carried out using a computational fluid dynamics (CFD) model ...
Geometry Assessment of Variable Displacement Vane Pumps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper brings to evidence the effect that geometry of the stator ring of variable displacement radial pumps bears on performance characteristics of these units. The type of motion of the ...
Analysis of Damage of Ball Bearings of Aeronautical Transmissions by Auto-Power Spectrum and Cross-Power Spectrum
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fourier analysis is used as a framework in which to obtain spectral estimates for nonstationary discrete time signals. Analysis of the auto-power spectrum and the cross-power spectrum makes it ...
Multicell Homogenization of One-Dimensional Periodic Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Much attention has been recently devoted to the application of homogenization methods for the prediction of the dynamic behavior of periodic domains. One of the most popular techniques employs ...
Simplified Approach to Evaluate Creep and Shrinkage Effects in Steel-Concrete Composite Beams
Publisher: American Society of Civil Engineers
Abstract: A simplified approach to evaluate creep and shrinkage effects in a steel-concrete composite beam with rigid or deformable connections, based on the age-adjusted effective modulus method, is presented. An aging coefficient, ...
