Damping Systems for Controlling Wind Induced Motions of Structures
This paper presents the state-of-the-art in damping systems for controlling wind induced motion of structures and their applications in the U.S. and Japan. Both passive and active systems...

Characterization of an ER Active Member
In the presence of strong electric fields (kV/mm), electrorheological (ER) materials change form viscous fluids to yielding materials. The class of ER materials used in this study have...

Low Strain Dynamic Testing of Wood Piles Supporting an Existing Pier
This paper presents a case history where low strain dynamic testing was performed to test wood piles supporting an existing structure. Under consideration is a 183 m long wooden pier constructed...

Dynamic Model for Analysis of Concrete Pavements
A new dynamic finite-element computer program, DYNA-SLAB, for the analysis of jointed concrete pavements subjected to moving transient loads is presented. The structural model for the...

Synopsis of a Manual on Structural Fire Protection
Structural Fire Protection : Manual of Practice was published in 1992 by the American Society of Civil Engineers. The Manual has two major parts. Part I (Chapters 1 to 3) introduces the...

Estimation of Structural Damping of Buildings
The full-scale data on damping ratio are collected from 77 buildings within Japan. Almost all data are obtained from vibrations with a very small amplitude such as microtremor, man-power...

Diaphragm Action of Cladding in Low-Rise Metal Buildings
An investigation of the contribution of cladding to the lateral stiffness of a metal building is presented in this paper. The diaphragm action of the cladding tends to redistribute the...

Uplift Resistance of Plywood and OSB Roof Sheathing
A test program to determine the resistance of plywood and OSB roof sheathing to uplift pressures created by wind flowing over a residential roof structure will provide valuable data to...

3-D Dynamic Analysis of the Brent-Spence Through-Truss Bridge
A three dimensional finite element model is developed for the free vibration analysis of main bridge. The model was calibrated by comparing the free vibration analysis results with ambient...

Response Study of a Flexible Building Using Three Earthquake Records
This paper examines the response of a flexible building during three earthquakes. The records from the building are long and contain low frequencies. The site frequency (0.33-0.38 Hz)...

Teaching Structural Loading: A Case Study
CVEG 4803: Structural Loading course was formulated three years ago as an undergraduate senior elective course. In this course structural dynamics is introduced for one third of the course....

Experimental Measurements of Dynamic Loads Imposed by Moving Crowds
Dynamic forces generated by moving occupants were measured using an instrumented forces platform. Experiments were conducted for several sets of loads due to individuals and groups of...

Prediction of Structural Response to Large Earthquakes by Using Recordings From Smaller Earthquakes
The feasibility of predicting structural response to large earthquakes by using recorded responses from collocated smaller earthquakes is investigated. Records from large earthquakes can...

Gust Speeds in Hurricanes
Based on strip-chart records of wind speeds representing 11 recording stations and four hurricanes, it is concluded that gust factors for hurricanes generally exceed the gust factors proposed...

Impact of Non-Gaussian pdf on Reliability Estimates for Deep Water Platforms
The offshore community has invested a great deal in the analysis and design of compliant deep water platforms such as tension leg platforms (TLPs) and more recently spar platforms. Tension...

Effects of Sea Surface Movement on Offshore Structures
Examinations are made of the effects of the sea surface movement on the fundamental model response of deep-water, Wave-excited offshore structures. These effects are accounted for by using...

Seismic Response of Concrete Tilt-Up Systems
A Summary of the measured dynamic response of a one-story, till-up warehouse located in Hillister, California, is presented. Acceleration and relative displacement histories may be used...

AWS versus AIJ Tubular K-Connection Design Rules
Among various existing design rules for circular tubular connections, the AWS rules are compared with the AIJ rules because of differences between the two. Subjects of discussion include...

The Behaviour and Design of Stressed-Arch (Strarch) Frames
The paper presents an overview of the stressed-arch structural system and the associated research program undertaken at the University of Sydney between 1988 and 1992. The objectives of...

Spherical Domes Subjected to Horizontal Earthquakes
The purpose of this paper is to get a powerful tool for response analysis of a spherical dome subjected to dynamic excitation based on mathematical analytic method, i.e., the Galerkin...
