Refinements in Pseudo-Dynamic Test Procedures
One of the major concerns in seismic testing is whether the loading conditions imposed on a structure adequately represent those that might occur during a major earthquake. Response simulation...

Response of the San Juan Bautista 156/101 Bridge to the 1979 Coyote Lake Earthquake
Strong-motion accelerograms are used to examine the response of a multiple-span highway bridge to earthquake loading. Estimates of modal frequencies and damping values for the first two...

Nonlinear Dynamic Response ofWindow Glass Plates Using Finite Difference Method
C. V. G. Vallabhan has established an efficient iterative procedure to solve the Von Karman nonlinear plate equations using finite difference method for a rectangular plate. Here the method...

System Identification Applied to Pseudo-Dynamic Test Data: A Treatment of Experimental Errors
A single-input single-output system identification technique, used to estimate the modal properties of a full-scale six-story steel structure tested within its elastic range by the pseudo-dynamic...

Green's Function Implementation for Pile Analysis
This paper describes the implementation of a new Green's function based on a layer stiffness approach in a boundary element analysis of harmonically loaded pile groups embedded...

Modified Dynamic Condensation Method
This paper presents a modification of the Dynamic Condensation Method for the reduction or condensation of problems in structural dynamics. The proposed modification substantially reduces...

Diffraction Forces on Axisymmetric Bodies
Use of a Green function satisfying the governing differential equation and all boundary conditions except those on the boundary of the structure yields an integral equation, when these...

Approximate Solutions for Layered Foundations
A simple approximation to the dynamic response of foundations resting on layered soil profiles is presented. The approximation is based on an equivalent radiation damping which is numerically...

Nonlinear Response Combination in Seismic Analysis
Simple, approximate methods are developed to evaluate the maxima of response measures which are nonlinear functions of modal responses to seismic input. Examples for such response quantities...

Dynamic Response Moments of Random Parametered Structures with Random Excitation
First and second order statistical response moments are formulated for linear multi-degree of freedom dynamical systems having both random load and random structural characteristics. A...

Response of Embedded Foundations: A Hybrid Approach
A hybrid approach to study the dynamic through-the-soil coupling between adjacent foundations embedded in a uniform soil model when subjected to harmonic external forces and seismic excitation...

Modeling for Finite-Element Soil-Structure Interaction Analysis
The modeling for finite-element soil-structure interaction analysis for embedded structures is evaluated in an attempt to resolve the issue related to the elevation at which design ground...

Boundary Zone Superposition Method for Linear and Nonlinear Dynamic Analysis of Infinite Domain Problems
The method is applicable to problems where input loads are imposed from within the finite element model or to problems where disturbances outside the finite element model generate input...

On Analysis of Dynamic Structure/Media Interaction
A version of the Global-Local Finite Element Method (GLFEM) is applied to the analysis of soil-structure interaction under steady-state excitation. The soil medium is considered to be...

Bounded State Control of Structures with Uncertain Parameters
The control of linear systems in the presence of set constrained external disturbances has been investigated maintaining the states in a prespecified region by estimating the maximum reachable...

Electronic Computation
The papers included in this book were presented during the thirteen sessions of the Ninth ASCE Conference on Electronic Computation. Topics addressed represent a wide spectrum of computer...

U.S. Navy's First Double Deck Pier
The present single level concept of pier construction limits the pier-side service to the fleet. With the ever increasing requirements for utilities to the ships, and maintenance and training...

Construction Approaches to the Navy's Floating Pier Concept
The subject of this paper is a floating pier which is currently under evaluation as a more cost-effective solution for berthing Navy ships. This new approach to pier design was sponsored...

Roller Compacted Concrete Pavement for Marine Terminals
This paper describes recent intermodal yard paving projects at the Port of Tacoma, Washington which have utilized a relatively new paving process known as Roller Compacted Concrete (RCC)....

Marina Design and Environmental Concern
Research initiated by a Florida Cabinet Resolution of August 6, 1974, has generated two models for the evaluation of the impact of marina development on coastal waters. One, a complex...
