    • DYNAMIC RESPONSE OF GROUND-EXCITED BUILDING FRAMES 

      ROEHL, JOAO LUIS PASCAL (1972)
    • Dynamic response of hazardous liquid-waste storage tanks used in nuclear facilities 

      Padmanaban, Shivakumar (1996)
      This dissertation presents a comprehensive study of the dynamic response of storage tanks containing high-level radioactive wastes in nuclear facilities. Of the many issues that are peculiar to these systems, four important ones have been studied. Accordingly, the study is presented in four parts. The first part deals with the dynamic response of ...
    • Dynamic response of liquid storage tanks subjected to coherent and incoherent ground motions 

      Padmanaban, Shivakumar (1992)
      A comprehensive study of the response of liquid storage tanks subjected to ground induced lateral excitations is presented. Wall flexibility affects the response coefficients of tall tanks significantly. In general, response coefficients for tanks are relatively insensitive to super-structure parameters. A simplified procedure for evaluating inertial ...
    • Dynamic response of machine-foundation systems 

      Marshall, Donald William (1965)
      A method of analysis is presented for the dynamic response of large machine-foundation systems. The general case of several machines on a common flexible mat is considered. The origin and types of machine exciting forces are discussed. Particular emphasis is given to the unbalanced inertial forces in reciprocating gas compressors. It is with this ...
    • Dynamic response of multi-degree of freedom structure with sliding isolation system and uplift 

      Vemuru, Venkata Srivishnu Mohan (2010)
      In this study the two dimensional dynamic response of a Multi Degree of Freedom (MDOF) sliding isolated structure permitted to uplift is studied. The MDOF superstructure is supported by two sets of sliding bearings situated at both the ends of the base mat. The foundation supporting the sliding bearings is assumed to be flexible and modeled using two ...
    • Dynamic response of shear beam type buildings 

      Goncalves da Silva, Manuel Americo (1967)
      An analytical Investigation is made of the dynamic response of multi-degree-of-freedom shear beam type buildings excited by transient lateral motions of the base. The response quantities studied are the horizontal displacements of stories relative to the base, the interfloor deformations, the shear forces and induced overturning moments at the story ...
    • Dynamic response of simple pile-structure systems 

      Khurana, Sandeep (1990)
      This dissertation is composed of two parts. In the first part, a comprehensive study is made of the harmonic response of a rigid mass or a mass-sprint system supported on a pile driven in a homogeneous elastic medium. The objectives are to assess the effects of the various factors that affect the response of the system. The second part deals with the ...
    • Dynamic response of simple systems to periodic forces 

      Dotson, Kirk Wayne (1983)
      A study of the response of viscously damped single-degree-of-freedom systems to non-harmonic periodic excitations is presented. The objectives have been (1) to assess the effects of the various factors that affect the response of such systems; and (2) to present information and concepts with which the salient features of the response may be identified ...
    • Dynamic response of single-degree-of-freedom bilinear systems 

      Bielak Radoshycka, Jacobo (1966)
      An analytical investigation is made of the dynamic response of bilinear single-degree-of-freedom systems excited by transient lateral motions of the base. Both elastic and hysteretic systems are studied. The input motions considered include a half-cycle velocity pulse, a half-cycle displacement pulse, a full-cycle displacement pulse, and an earthquake ...
    • Dynamic response of soil-wall systems 

      Giarlelis, Christos M. (1997)
      A two-part study of the dynamic response to horizontal base shaking of vertical, rigid and flexible walls retaining a uniform soil stratum is presented. The first part deals with available pseudostatic, limit-state methods of analysis; specifically, the Mononobe-Okabe method and its extension by Richards and Elms. Following a detailed review of these ...
    • Dynamic Self-Stiffening in Liquid Crystal Elastomers 

      (2013)
      Biological tissues have the remarkable ability to remodel and repair in response to disease, injury and mechanical stresses. Synthetic materials lack the complexity of biological tissues, and man-made materials that respond to external stresses through a permanent increase in stiffness are uncommon. Here we report that polydomain nematic liquid crystal ...
    • Dynamic Senor-Based Fault Detection for Robots 

      Visinsky, Monica L.; Cavallaro, Joseph R.; Walker, Ian D.; Center for Multimedia Communication (1993-09-01)
      Fault detection and fault tolerance are increasingly important for robots in space or hazardous environments due to the dangerous and often inaccessible nature of these environs. We have previously developed algorithms to enable robots to autonomously cope with failures or critical sensors and motors. Typically, the detection thresholds used in such ...
    • Dynamic shrinkage processes 

      Kowal, Daniel R.; Matteson, David S.; Ruppert, David (2019)
      We propose a novel class of dynamic shrinkage processes for Bayesian time series and regression analysis. Building on a global–local framework of prior construction, in which continuous scale mixtures of Gaussian distributions are employed for both desirable shrinkage properties and computational tractability, we model dependence between the local ...
    • Dynamic simulations of potential methane release from East Siberian continental slope sediments 

      Stranne, C.; O’Regan, M.; Dickens, G.R.; Crill, P.; Miller, C.; (2016)
      Sediments deposited along continental margins of the Arctic Ocean presumably host large amounts of methane (CH4) in gas hydrates. Here we apply numerical simulations to assess the potential of gas hydrate dissociation and methane release from the East Siberian slope over the next 100 years. Simulations are based on a hypothesized bottom water warming ...
    • Dynamic soil pressures on deeply embedded structures 

      Younan, Adel Helmy (1994)
      The studies reported herein are motivated by the need to gain improved understanding of the response to earthquakes of deeply embedded and underground cylindrical tanks storing nuclear wastes, and develop rational but simple methods of analysis and design for such systems. The first part of the study, reported in Chapters 2 and 3, is concerned with ...
    • Dynamic soil pressures on embedded walls 

      Parikh, Vimal H. (1995)
      A comprehensive study is made of the response to horizontal base shaking of a uniform viscoelastic soil stratum retained by two vertical rigid walls. The system is assumed to experience a space-invariant horizontal motion along its base. Both harmonic and earth-quake ground motions are considered. The study is motivated by the need for a simple method ...
    • Dynamic soil pressures on rigidly and elastically supported embedded vaults 

      Attia, Magda Youssef (1993)
      A comprehensive study is made of an approximate model for the computation of the dynamic pressures and associated forces induced by ground shaking on rigid embedded vaults (2, 10). For rigidly supported vaults, it is shown that, due to the lack of shearing resistance of the medium surrounding the vault, the model is unable to predict the forces induced ...
