Corrosion monitoring research of New York City bridges by Raimondo Betti( )

1 edition published in 2014 in English and held by 209 WorldCat member libraries worldwide

In this study, an integrated methodology was developed that uses state-of-the-art sensing capabilities and non-destructive evaluation (NDE) technologies to assess the cable condition. A smart sensor system integrated with NDE technologies is an approach that shows potential for assessing the condition of suspension bridge cables. NDE technologies for direct detection of the corrosion damage (i.e., main flux method, magnetostrictive technology, and acoustic emission technology) were implemented, validated, and tested for suspension bridge cable applications. In addition, a network of sensors that can monitor the external and internal environment of such cables and provide information that can be used to indirectly assess the cable's deterioration conditions and their evolution over time were assembled and extensively tested. To recreate conditions as close as possible to real operating conditions, a cable mockup, which was 20 inches (508 mm) in diameter and 20 ft (6.1 m) long and subjected to 1,100 kips (4,893,043.76 N) and fully instrumented, was built at Columbia University and tested in an enclosed accelerated corrosion chamber. The same system was then installed on two panels of the Manhattan Bridge, and measurements of temperature, relative humidity, and corrosion rate in the cable interior were successfully recorded for almost 1 year from November 2010 to September 2011

Seismic damage assessment of reinforced concrete members by Y. S Chung( Book )

2 editions published in 1987 in English and held by 11 WorldCat member libraries worldwide

"This report starts with a fundamental discussion of damage, which reinforced concrete members sustain under large inelastic cyclic loads similar to those experienced during a severe earthquake. A large number of damage indices, which have been proposed in the literature, are discussed and critically evaluated under the criterion of usefulness for structural analysis and seismic risk assessment. A new damage index is presented, which the authors believe is a rational measure of the physical response characteristics of reinforced concrete members and better suited for nonlinear structural analysis than those that have been proposed previously. Unfortunately, experimental data, on which the calibration of the new model depends, are scarce, therefore it is recommended that systematic low-cycle fatigue tests be undertaken to strengthen the theoretical basis for the model."--Abstract

Automated seismic design of reinforced concrete buildings by Y. S Chung( Book )

2 editions published in 1988 in English and held by 9 WorldCat member libraries worldwide

"A new automatic method for the seismic design of reinforced concrete frame buildings is presented. A new damage index is reviewed, which serves as a measure of a member's residual energy dissipation capacity and is suitable as a control parameter in an automated design method. The method proposed aims for a uniform energy dissipation throughout the building frame, as measured by the individual member damage indices. The new damage index is modeled on the low-cycle fatigue phenomenon exhibited by reinforced concrete members subjected to strong inelastic cyclic loads. It accounts for the observed stiffness and strength deterioration, includes a modified Miner's Rule for variable amplitude loading, and considers the effect of load history. These features make the damage index a useful measure of a member's capacity to resist further cyclic loading. The automatic design method is based on a thorough study of the effects of three important design variables, the longitudinal reinforcement, the confinement steel, and member depth. Design rules derived for the large number of numerical studies allow an iterative improvement of a preliminary design until the distribution of damage indices has reached a user-specified degree of uniformity. The usefulness of this design method, which incorporates aspects of a knowledge-based expert system, is demonstrated with a typical four-story, three-bay office building."--Abstract
A finite element formulation for nonlinear, viscoplastic material using a Q-model by Osei K Gyebi( Book )

2 editions published in 1987 in English and held by 7 WorldCat member libraries worldwide

"A direct comparison of the rheological behavior of a mass supported by a complex spring and a mass supported by a spring-dashpot arrangement provides a means of establishing a relationship between material damping in the frequency domain and the frequency dependent Q(ro). For the special case where Q(ro) is constant over a given frequency range, the expansion of Q-1(ro) into a Laurent Series yields a set of damping coefficients whose values are determined by minimizing the mean square error of the series over the prescribed frequency range. The resulting damping expression is used in conjunction with an elastoplastic constitutive matrix in finite element discretization to produce a viscoplastic model suitable for a direct step by step time integration. The proposed model is very convenient for use in finite element discretization for the analyses of earthquake, blast, shock, and other soil-structure interaction problems involving cyclic loading."--Abstract
Digital simulation of seismic ground motion by Masanobu Shinozuka( Book )

2 editions published in 1987 in English and held by 7 WorldCat member libraries worldwide

"The method of spectral representation for uni-variate, one-dimensional, stationary stochastic processes and multi-dimensional, uni-variate (as well as multi-dimensional, multi-variate) homogeneous stochastic fields has been reviewed, particularly from the viewpoint of digitally generating their sample functions. This method of representation has then been extended to the cases of uni-variate, one-dimensional, nonstationary stochastic processes and multi-dimensional, uni-variate nonhomogeneous stochastic fields, again emphasizing sample function generation. Also, a fundamental theory of evolutionary stochastic waves is developed and a technique for digitally generating samples of such waves is introduced as a further extension of the spectral representation method. This is done primarily for the purpose of developing an analytical model of seismic waves that can account for their stochastic characteristics in the time and space domain. From this model, the corresponding sample seismic waves can be digitally generated. The efficiency of this new technique is demonstrated with the aid of a numerical example in which a sample of a specially two-dimensional stochastic wave consistent with the Lotung, Taiwan dense array data is digitally generated."--Abstract
Symbolic manipulation program (SMP) : algebraic codes for two and three dimensional finite element formulations by X Lee( Book )

2 editions published in 1987 in English and held by 7 WorldCat member libraries worldwide

A computer algebra package entitled the Symbolic Manipulation Program (SMP) has been briefly reviewed. Its capabilities of handling the Finite Element Method (FEM) and Matrix Structure Analysis (MSA) are studied. The applications of using SMP in nonlinear FEM and reliability analysis of the nondeterministic systems are demonstrated. The possibilities of translating the output from SMP into higher level languages such as C and FORTRAN are also investigated in order to communicate with the existing computer codes and to obtain the numerical results more efficiently. A number of SMP programs have been developed and are listed in this report. Finally, the potential applications and restrictions of SMP to engineering problems are also discussed herein

Post-ductility : metals in architecture and engineering by Michael Bell( Book )

1 edition published in 2012 in English and held by 6 WorldCat member libraries worldwide

Metals, as surface or structure- as the generators of space, play a role in nearly every strain of modernisation in architecture. They define complete geographies of work, production, and political life. Non-architectural metals delivered in cars, and hard goods in the United States and worldwide have all been sourced as the engines of the sprawling late twentieth-century city in all of its forms. But in the received aspects of architectural history, metals, and in particular steel, remain less diluted; they are presented as intrinsic to the profession as material precedes concepts- they are carriers of architectural meaning
Viscous flow of a suspension of liquid drops in a cylindrical tube by William A Hyman( )

3 editions published in 1967 in English and held by 5 WorldCat member libraries worldwide

Viscous flow of a liquid in a circular cylindrical tube containing an infinite line of immiscible liquid drops in suspension is considered. It is assumed that a surface tension acts which is large enough to hold the drops in a nearly spherical shape and that the drops are equally spaced along the tube axis. Three cases are considered: (1) axial translation of the drops due to a body force (2) flow of the external fluid past the drops, and (3) flow of the external fluid and liquid drops under an imposed pressure gradient. Both fluids are taken to be Newtonian and incompressible, and the equations of creeping flow are used. Exact solutions are obtained in the form of infinite series. The drag on the drops and the pressure gradients are computed for a range of drop radius to tube radius up to 0.8, and for the ratio of drop viscosity to external fluid viscosity from zero to 100. The results show that the drag and pressure drop per sphere increase with both increasing drop spacing and drop radius. The presence of the internal motion of the drops reduces the drag and pressure gradient below those for rigid spheres. (Author)

Extensions of extremum principles for slow viscous flows by Richard Skalak( Book )

2 editions published in 1969 in English and held by 5 WorldCat member libraries worldwide

Several generalizations of theorems of the types originally stated by Helmholtz concerning the dissipation of energy in slow viscous flow have been given recently by Keller, Rubenfeld and Molyneux. These generalizations included cases in which the fluid contains one or more solid bodies and drops of another liquid assuming the drops do not change shape. Some further extensions are given which allow for drops which may be deformed by the flow and include the effect of surface tension. The admissible boundary conditions have also been extended and particular theorems applicable to infinite domains, spatially periodic flows and to flows in infinite cylindrical pipes are derived. Uniqueness theorems are also proved. (Author)
