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...
Building Motion in Wind
The trend towards higher structural efficiency and hence lower cost has resulted in a generation of lighter and more flexible buildings with a lower inherent capacity for energy dissipation...
Measurement of Vertical Ground Vibrations
This paper examines the use of surface and embedded mountings, to which transducers are attached for the measurement of free field vertical ground vibrations. Upper limits to the frequency...
Seismic Interaction Among Numerous Masses Founded on a Viscoelastic Stratum
The steady-state harmonic response of systems comprising numerous masses resting on a homogeneous, viscoelastic stratum with hysteretic damping is studied. The stratum, bearing on a rigid...
Design of High-Technology Facilities from the Vibration Standpoint
High-technology facilities, such as those used for the production of integrated circuits or for optics research, generally require extremely limited vibration environments. Suitable precautions...
Isolating Earthquakes
The Foothills Communities Law and Justice Center in Rancho Cucamonga, Calif., is the first U.S. building to rest on base isolators for protection against a possible earthquake of 8.3 Richter....
Iceberg Interactions with Offshore Structures
Various aspects include the component problems corresponding to iceberg drift in open water, iceberg drift in the vicinity of a large offshore structure, wave-induced motions of a berg,...
Design of an Icebreaking Offshore Supply Vessel
There are two basic scenarios for icebreaking support vessels. The first is the delivery of drilling fluids and supplies to drilling units and other development operations. The second...
Soil-Pipeline Interaction During Ground Movement
The problem of the elastic interaction is examined between a pipeline or a group of connected flexible connected pipelines and the surrounding soil medium, which is induced by ground movement....
Arctic Oil Spills in Relationship to Sea Ice Motion
Sea ice on a scale of a few kilometers must be treated as a granular material rather than a continuum. The floes are in nearly constant motion relative to a fixed frame and each other....
