Automated Truncation of Ritz Vector Basis in Modal Transformation
Publisher: American Society of Civil Engineers
Abstract: The number of load‐dependent Ritz vectors required for an accurate dynamic analysis, using the mode superposition method, depends on both the spatial distribution and the spectral (frequency) content of the loading. In ...
Use of Special Ritz Vectors in Dynamic Substructure Analysis
Publisher: American Society of Civil Engineers
Abstract: A numerical method is presented for the dynamic response analysis of large structural systems that are modeled as substructures. The method is similar to the component mode synthesis technique; however, the generation of ...
Turbulent Flow Hydrodynamic Experiments in Near-Compact Heat Exchanger Models With Aligned Tubes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hydrodynamic experiments measuring longitudinal pressure-drop versus flow rate are conducted for turbulent flow of air (channel hydraulic diameter based Reynolds number range of 2300 to 6860) ...
Surge Pressures in Liquid Transfer Lines
Publisher: The American Society of Mechanical Engineers (ASME)
Permeability and Form Coefficient Measurement of Porous Inserts With Non-Darcy Model Using Non-Plug Flow Experiments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Permeability (K) and form coefficient (C) are the characteristic hydraulic properties of any porous medium. They are determined simultaneously, for known fluid thermo-physical properties by using ...
Regional Rainfall Frequency Analysis via Stochastic Storm Transposition
Publisher: American Society of Civil Engineers
Abstract: In a previous study, Foufoula‐Georgiou (1989a) investigated a stochastic storm transposition (SST) approach as a possible methodology of assessing the probability of exceedance of extreme precipitation depths over a ...
Unstable Self-Excitation of Torsional Vibration in AC Induction Motor Driven Rotational Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The most common NEMA Design Classes of AC induction motors have speed-torque characteristics that can give rise to unstable self-excitation of torsional vibration in rotational systems during ...
Closure to “Aspects of Virtual Master Builder” by Victor E. Sanvido, Steven J. Fenves, and John L. Wilson (July, 1992, Vol. 118, No. 3)
Publisher: American Society of Civil Engineers
Blast Vibration and Environmental Loads Acting on Residential Structures: State-of-the-Art Review
Publisher: American Society of Civil Engineers
Abstract: This paper provides a unique literature review of cracking defects developing in low-rise residential structures as a result of deformation caused by environmental loads and low-level blast vibrations. Characteristics of ...
Aspects of Virtual Master Builder
Publisher: American Society of Civil Engineers
Abstract: The current processes of planning, design, construction management, and facility management are driven by the collection and communication of large quantities of knowledge, data, and intent, much of which are lost due to ...
