Floating Bridges in Short-Crested Random Seas
Four large concrete floating bridges located in Washington State have been the subject of extensive analytical modeling for dynamic response to storm waves. The dynamic analysis of the...

Significance of Nonlinear Modeling of R/C Columns to Seismic Response
Columns in reinforced concrete (R/C) structures exhibit complex hysteretic behavior during earthquakes. This can significantly influence predictions of overall response and damage distribution....

Earthquake Analysis of Liquid Storage Tanks
In the design of modern liquid storage tanks, it is of technical importance to examine their safety against earthquake damage. The methodologies used in design do not account for the major...

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...

Explosion Hazards to Urban Structures
Manufacture, storage and transportation of chemicals capable of exploding at energy levels comparable to TNT has increased in recent years. Land areas adjoining such facilities and transportation...

Some Experimental Results on the Dynamic Behaviour of a 40m Guyed Mast
This paper presents the first results and elaborations obtained from the tests of an experimental 40m tall guyed mast. The instruments installed to date are a cup anemometer on the mast...

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...

Seismic Behavior of Long-Span Cable-Stayed Bridges
Special features of the earthquake-response analysis of cable-stayed bridges, subjected to multiple-support excitation, are presented including a basis for calculation of seismic forces...

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...

Performance of Existing Buildings: Results of Benchmark Structure Analyses Performed in U.S.-Japan Workshops
In response to the need for better understanding of current safety evaluation methodologies, three U. S. -Japan workshops have been conducted on the evaluation of the performance of existing...

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...

Wind Loads and Building Response Predictions Using Force Balance Techniques
The use of force balance techniques to measure mean and dynamic wind loads on models of buildings and structures is discussed. Advantages of using force balance techniques over estimating...

Building Identification: Needs and Means
The need to conduct 'system identification' of existing buildings by nondestructive testing is discussed. A recommended flow-chart is exemplified. Existing dynamic...

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...

Dynamics of 3-D Base Isolated Structures
The work described in this paper concerns the dynamic behavior of asymmetric base isolation systems consisting of laminated rubber bearings and hysteretic dampers. It is shown in this...

Earthquake Response of Five Story Reinforced Concrete Masonry Test Building
In 1986, a full-scale five story reinforced masonry test building is to be constructed in the Japan Building Research Institute Large-Scale Structure Test Laboratory, and through 1987...

Adaptation of Modal Testing Procedure to Shaker Tables
This article presents a technique for adapting current modal testing procedures to shaker table tests commonly used for qualification tests of nuclear and space related equipment. It involves...

Optimal Collection of Data for Parameter Identification
In this paper, the author attempts to study the optimal spacing of measurements for a structural system modelled by a single-degree-of-freedom oscillator so that the variance of one or...

Research Topics in Structural Identification
The authors examined a variety of possible research topics including identification and detection of nonlinearities, model improvement approaches, damage identification, power estimation...

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...
