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...
On Reliability-Based Structural Optimization for Earthquakes
Previous studies of reliability-based structural optimization have been extended in order to investigate the applicability of the linear statistical model in cases where random parameters...
Modeling 3-D Response in R/C Frame-Wall Structures
As part of the recent U. S. -Japan Cooperative Research Program on the seismic performance of buildings, a 1/5-scale model of a 7-story reinforced concrete frame-wall structure, was constructed...
Earthquake Response Simulation Capacity of Pseudo Dynamic Testing?Experimntal Demonstration and Analytic Evaluation
The response accuracy of the pseudo dynamic test was evaluated from the shake table and pseudo dynamic tests conducted for a two story steel braced frame model. The obtained responses...
Research Topics in Structural Identification

Soil-Structure Interaction at the Waterfront
In 1981 the Naval Civil Engineering Laboratory (NCEL) undertook a review of available material models. Comparison was made between test data and model predictions. Based on this study,...
Random Vibration of Mass-Loaded Rectangular Plates
The classical method of separation of variables in conjunction with the Green's function of the vibrating plate is used to obtain the solution of the free vibration problem...
Stochastic Response for Tertiary Systems
A modal superposition method is presented for obtaining the response of a single-degree-of-freedom tertiary subsystem mounted on a primary-secondary system. The method is direct in that...
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...
Dynamic Response of Systems with Uncertain Properties
This paper addresses the methodology for determining the response of a structure modelled as single-degree-of-freedom system whose mass, damping and stiffness parameters are known only...
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...
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...
Constrained Viscoelastic Layers for Passive Vibration Control of Structures
Infills with constrained viscoelastic layers for increasing the energy absorption capacity of structures are examined. The infills are expected to 'work' in the...
An Experimental Study of Active Structural Control
An experimental investigation is made concerning the possible application of active control to structures under seismic excitation. The experimental facilities and structural model are...
Dynamic Behavior of Full-Scale Wood Diaphragms
Experimental testing of full-scale wood diaphragms has been performed at Washington State University to determine basic dynamic properties. Ten diaphragms, including walls, floors, and...
The Atlantic Palace: Part I Structural System Selection Based on Wind Tunnel Testing
The location of the structure in a coastal area susceptible to high winds, the irregular shape and height of the building and the desire for more accurate wind loading and acceleration...
Dynamic Response Correlation Using Simplified Models
A simplified model for building response which has a W. Ramberg-W. R. Osgood hysteresis is developed in a discrete sense. It is then used to evaluate the response of an instrumented, bearing...
The Application of Computer Simulation in the Design of Marine Terminals and the Scheduling of Ship Traffic
This paper describes a software package which simulates the operations of marine terminals. The computer programs were designed to assess the effectiveness of the available design alternatives...
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...
Siltation of the Port of Astoria
Sedimentation rates suddenly increased in the Port of Astoria, Oregon, immediately following the May 18, 1980 ash eruption of Mt. St. Helens. This ash was transported down the Columbia...
