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...
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...
Seismic Fragility Analysis of Sheahan Pumping Building
This paper presents a seismic fragility analysis of the Sheahan pumping building located in Memphis, Tennessee. In the analysis, seismic response is determined from the response spectrum...
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)...
Nonlinear Dynamic Response of an RC Structure with Advanced Cladding
Laser Generation and Detection of Ultrasound in Concrete
Laser ultrasonics is a non-contact nondestructive evaluation method that uses lasers to generate and detect elastic waves. In this work, laser ultrasonics is used to produce broadband...
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...
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...
Response of Truss Structures Subjected to Dynamic Loads During Member Failure
The paper presents a method for and results from an investigation of the response of a truss structure during the chain reaction of its member failure while subjected to external static...
Continuous Pulse Control of Structures with Material Nonlinearity
A control method is presented for reducing the dynamic response of structures in the inelastic material range using a control force from an active control system. The proposed method of...
Experimental Study on the Strut Type of Cable Net Membrane Structures
In this paper a new type of suspension membrane structure combined with a cable net is proposed, in which the supporting struts are arranged between the membrane surface and the cable...
Direct and Modal Analyses for Shape-Finding of Unstable Structures
Shape-finding analysis of unstable structures has been presented by using generalized inverse (Tanaka and Hangai, 1986). The 'Modal Analysis' using rigid body modes is elegant, but the...
