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...
Refinements in Pseudo-Dynamic Test Procedures
One of the major concerns in seismic testing is whether the loading conditions imposed on a structure adequately represent those that might occur during a major earthquake. Response simulation...
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...
Use of Vibration Tests to Determine Lateral Load Paths in Medium Rise Buildings
A structural system identification procedure is described in which an initial analytical model of a building is modified until it predicts accurately the mode shapes and natural frequencies...
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...
Three Phase Design for Wind Loads on Structures
The successful design of a structure requires three phases of work. These phases are: conceptual design, design development and design verification. The conceptual design is undertaken...
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...
Seismic Behavior of a Full-Scale K-Braced Steel Frame?Part I Gross Behavior
As a part of the U. S. -Japan Cooperative Research Program Utilizing Large-Scale Testing Facilities, a six-story, 2 by 2 bay, concentrically K-braced steel building was constructed in...
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...
Slab Participation in Frames under Lateral Loads
A unique opportunity to study slab participation was afforded by the U. S. -Japan Cooperative project on large scale testing. The data obtained from the full-scale 7-story building tested...
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
