New Directions in the Application of Probabilistic Concepts in the Seismic Analysis of Nuclear Power Plants
During the last 8 years, probabilistic concepts have been used in the seismic analysis of nuclear power plants. Probabilistic risk assessment (PRA) has been the primary vehicle for performing...

Coastal Hydrodynamics
This book includes papers presented at the ASCE Specialty Conference on Coastal Hydrodynamics Conference, at the University of Delaware, June 28-July 1, 1987. The papers review the state...

The Lanczos Method in Structural Dynamics
The solution of the equations of motion often results in the solution of an eigenvalue problem in which the system matrices are large. Traditionally, the solution of this problem has employed...

Improved Method for the Dynamic Response of Bilinear Systems
A procedure is presented to eliminate the error introduced in the step-by-step numerical integration of the equations of motion of hysteretic bilinear systems subjected to earthquake excitations...

Preliminary Seismic Risk Maps for Puget Sound
Ground shaking during Puget Sound earthquakes is characterized by irregularly shaped areas of high intensity ground motion, not all of which are correlated with soil type. Simulation of...

Seismic Risk Analysis of LNG Storage Tanks
This paper presents an approach to the seismic safety review of existing LNG storage tanks. The approach considers the seismic hazards from ground motion, surface fault rupture, and soil...

Importance of Phasing of Strong Ground Motion in the Estimation of Structural Response
In this paper, the influence on Fourier phase spectrum of seismic source directivity due to rupture propagation along the earthquake source is investigated. The phasing is described using...

Dynamic Testing of Structures Using the RESCUE Technique
This paper describes the most recent phase of an NSF supported program at SRI International to develop the technique of repeatable earth shaking by controlled underground expansion (RESCUE)...

Field Tests of Wind-Structure Interaction
The present study was initiated to investigate the possible causes for excessive lamp failure rates on High Mast illumination towers in the State of Minnesota. The study consisted of two...

Building Records from 1984 Morgan Hill Earthquake
The dynamic response of 23 structures instrumented by the California Strong Motion Instrumentation Program was recorded during the magnitude 6. 2 (ML) Morgan Hill earthquake of 24 April...

Stiffness Parameters Identification of Frames
Four widely used methods of structural system identification are presented. A new formula and its derivation, based on the Bayesian estimation theory, is given. Time domain responses of...

Vibrations of Submerged Solids in a Vibrating Container
Dynamic forces on a vibrating submerged solid cylinder in both closed and open-top rectangular containers are evaluated. The submerged cylinder is attached to the base of a dynamically-excited...

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...

Performance of an Earthquake Excited Roof Diaphragm
The objective of this paper is to study the earthquake performance of the roof diaphragm of the West Valley College gymnasium in Saratoga, California through a complete set of acceleration...

Performance of Viscoelastic Structural Dampers for the Columbia Center Building
Vibratory motion of structures such as buildings, bridges, and floors can be reduced by the use of viscoelastic (V. E. ) dampers. Such dampers transfer part of the vibratory energy of...

Trends in Containerships and Their Impact on Terminal Design
A revolution in ocean shipping operations, affecting both landside equipment and cargo handling methods, is underway. In today's container shipping industry, maximum efficiency...

Design Concepts for Floating Breakwaters
This paper describes a fundamental approach to the design of a floating breakwater based on the concepts of dynamic analysis of floating bodies. The process results in a relatively simple...

Port Design and Ship Characteristics
The close relationship between ship characteristics and terminal design is recognized and should be considered as integral part of the total transporation. Ship characteristics to be considered...

Ship Wave Prediction for Port and Channel Design
Several laboratory and field investigations of ship-generated waves have been conducted during the past twenty-five years. Typically, for a given ship, reported data consists of the height...

Marginal Wharf and Embankments?Seismic Design
This paper presents some of the seismic considerations used for the improvements at Berths 225 to 229 at the Port of Los Angeles. The design of the improvements was complicated by the...
