Improved Torsional Analysis Procedure for Single Story Structures Subjected to Seismic Motion
An analytical procedure is developed that enables designers utilizing the UBC planar lateral force procedure to accurately account for the additional lateral response due to torsion without...
Dynamic Field Response Studies and Earthauqke Instrumentation of the Meloland Road Overcrossing
Ambient vibration data was obtained at the Meloland Road Overcrossing near El Centro in California by The California Department of Transportation (CALTRANS) as part of a 1978 Federal Highway...
Nonlinear Response of SDOF Systems to Intraplate Earthquakes
It is well established that there are characteristics differences between intraplate and interplate earthquakes. A parametric study of SDOF systems indicates that there is also consistent...
A General Hysteresis Model for Wood Structures
To predict the dynamic response of a wood structure, its energy dissipation mechanism and hysteresis behavior must be appropriately modeled. This paper presents a new hysteresis model...
Wind Loads on Arena Roofs Using Aerodynamic Models
The concept behind an aerodynamic wind tunnel model used to predict dynamic response to wind excitation is the generalized load in a particular natural mode of vibration is measured ,...
85 Stories in Kuala Lumpur?The 5th and 6th Tallest Buildings in the World
A concrete core and cylindrical concrete tube structure provides a safe, elegant, efficient and constructible solution to the challenge of designing the world's 5th and 6th tallest buildings,...
Structural Design and Wind Resistance of Fukuoka Tower with T.M.D.
Fukuoka Tower, which was built in 1989, was projected as a monument, a observation tower and a broadcasting antenna with 234m high. In this tower, a Tuned Mass Damper(TMD) was set, in...
Predicting Turbine-Generator Foundation Vibrations
Two of the major considerations in the design of large turbine-generator foundations are to maintain the proper shaft alignment and to limit the vibration of the machine during operation....
Dynamic In-Plane Racking Tests of Curtain Wall Glass Components
This paper is concerned with the seismic performance of 'architectural.' or 'non-structural' building elements such as glass elements in curtain wall systems. A pilot study was undertaken...
Structural Response Using Stiffness Decoupler
The structural properties of a new stiffness decoupler developed by Hu, Kirmser and Swartz at Kansas State University, and its applications as an energy absorber and a device to isolate...
Response of Equipment in Structures Supported on Resilient-Friction Base Isolators Subjected to Ground Motion
In this paper, the response of equipment in structures on a particular friction-type device, the resilient-friction base isolator, is examined. The R-FBI is composed of layers of Teflon...
Robust Control for Buildings Under Earthquake
Robust control techniques are applied to civil engineering structures subjected to earthquake excitation. Full state feedback and observer based control laws are used to reduce the response...
Fluid Viscous Damper for Improving the Earthquake Resistance of Buildings
Experimental results are presented which demonstrate that the use of fluid dampers as add-on devices in moment resisting frames substantially increases damping and reduces seismic story...
Seismic Performance of Base-Isolated Building Structures
The theories and assumptions behind the base isolation technology are briefly described. As an illustration of its application, the base isolation of an existing 12-story hospital in Long...
Neural Networks in Structural Control
Let the response of a simple two-story frame to a stochastic dynamic excitation be controlled by activating suitable actuators. A neural network is trained to recognize, from the measurement...
Development of Bridge Load Model for LRFD Code
The load models are based on the available statistical data on dead load, truck loads and dynamic loads. The paper deals mostly with the static live load. The model is derived from truck...
Dynamic Inelastic Analysis of Tall Buildings
Members with undesirably early formed plastic hinges as well as excessive conservatism introduced in the preliminary design of tall buildings can be identified by the behavior state study...
