New Techniques in Forced Vibration Testing
Forced vibration testing is a well established technique as indicated by references 1 to 8. This paper describes a system for forced vibration testing developed over two years during work...
Some Aspects of Bridge Instrumentation
This paper provides some guidelines about the proper arrangement of strong motion instruments for the proper assessment of some particular phenomena that have been either observed in past...
Seismic Response Analysis of Two Major Bridge Structures
The seismic response analyses of two major bridge structures have been conducted. In these two bridges, portions of the piles are either submerged in the water or free-standing within...
Evaluation of Seismic Strengthening of an Existing Building Using Base Isolation
This paper summarizes a study performed by Englekirk and Hart, Inc. to evaluate the feasibility of using base isolation to seismically upgrade an existing highrise building. To realize...
A Discrete Model for the Estimation of the Elastic Abutment Stiffness
The purpose of this paper is the presentation of a simple method for the estimation of the abutment stiffness. In this method, the abutment is represented as a uniform rigid plate with...
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...
Interaction Effects in Vertically Excited Steel Tanks
Following a brief review of the hydrodynamic effects induced by a vertical component of ground shaking in liquid-filled, circular, cylindrical, steel tanks that are rigidly supported at...
Rigid Body Random Rocking Prediction
The stochastic rocking of a rigid block due to shaking of its foundation is examined. The foundation is flexible (Winkler) and its independent springs and dashpots separate from the block...
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...
Response of Underground Pipelines to Dynamic Loads
The results of an investigation of the forced response of an underground pipeline due to dynamic loads are presented. The pipe is modelled as a linearly elastic shell element and the surrounding...
Procedures for Predicting Settlements in Sands
In many cases, the prediction of settlements of footings on sands involves use of empirical rules. Although many approaches are reported in the literature, the relative accuracy of these...
Settlement of Light Buildings on Loose Sand
This paper reviews several cases of settlement of lightly loaded structures supported on granular soils. The concept of settlement ratio is presented. Measurements indicate that the settlement...
Pressuremeter and Shallow Foundations on Sand
The settlement and bearing capacity rules for the design of shallow foundations on sands using the results of pressuremeter tests are reviewed. The results of four footing tests to failure...
Structural Settlements at a Major Power Plant
The foundation design for the Intermountain Generating Station was based on comprehensive geotechnical investigations that included cone penetrometer tests, borings, pressuremeter tests,...
Blasting Densifies Sand
Constructing the Jebba Dam on Nigeria's Niger River required in-place densification of large volumes of loose sand to record depths of up to 131 ft. Vibrocompaction was used...
Alternative Dispute Resolution
Usually it takes far less money and time to resolve a construction dispute if a lawsuit and court trial can be avoided. In the mini-trial, te two or more parties agree to radically reduce...
Innovations in the Design of Electrical Transmission Structures
New concepts are being advanced for the design of electrical transmission structures. The papers in this book cover the following: weather-element loading conditions, structural options,...
Tacoma Terminals Pier Designed for Economy
This pier is a representative and highly refined sample of what is known as the Puget Sound system of construction, an economical system that maintains the durability necessary in the...
Systematic Design of Marinas for Ice Condtions
A systematic approach and recommendations are presented for design engineers use in planning and building safe docks and marinas, and in reducing the expense of damages which ice causes....
