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...

Extreme Winds Estimation by `Peaks Over Threshold' and Epochal Methods
With a view to applying the 'peaks over threshold' method to the estimation of extreme wind sped data, we perform Monte Carlo simulations for which the parameters of the population distributions...

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...

Design and Analysis of the 712 Fifth Avenue Structure
New York City's 712 Fifth Avenue is an extremely-slender concrete tube tower. This text addresses the structure's lateral structural system, wind analysis, computer model, thermal analysis...

A New Way of Teaching Structural Engineering With the `AN/EX' Mini-Laboratory
Students in the AN/EX lab first use a custom-written preprocessor to generate a proper input file to run the professional-level M-STRUDL structural analysis program to predict the load...

Deployable Mesh Reflector
This paper presents a new deployable reflector for space applications, based on a deployable edge frame that deploys and prestresses a 'rigid' cable network. The edge frame consists of...

On some Problems of the Multicriteria Optimization of the Spatial Grid Structures
One can not think contemporary structure designed without consciously complying with optimization methods. Creative activity of engineers have to be optimal or semi-optimal. It is necessary...

Blast Demolition of Reinforced Concrete Industrial Chimneys
On some of recently demolished chimneys, transient measurements were taken, in the vicinity of the tilting hinge, during the process of falling down. Thus, corresponding dynamic computational...

Comparison of Two different Models of a Shell Roof
The main purpose of this study is to compare a physical model of a shell roof with a theoretical model of the same shell roof in order to verify the reliability of the Homeostatic Model...

Optimal Design Conception of Grid Domes in Practice
In this paper, the optimal design conception of grid domes in practice is presented. The classical dome shell structures covering some irregular boundaries often seems not to be satisfied...

Simulation Procedure for Buckling Behaviors of a Reticular Dome
Complex behaviors of the ball-joint connection, especially used in steel space structures, are expressed in the numerical model to confirm the estimative ability of such a model by comparing...

Combinatary Net-Shell Roofs of Elliptic Paraboloid of Zhaoqing Gymnasium
Zhaoqing Gymnasium is a multi-functional sports building, whose structural modelling takes Zhaoqing City Flower(Lotus) as the main theme; adopts a combinatory ellipic paraboloid net-shell...

Effects of Spatial Triangulation on the Behavior of Tensegrity Domes
A number of long span 'tensegrity' dome type structures have recently been realized pursuant to the inventions of R. Buckminster Fuller and David H. Geiger. These structures have demonstrated...

Vibration Characteristics of Suspension Membrane Structures
The present paper specifies fundamental vibration characteristics obtained from experiment on the model of the suspension or the framed membrane structure. The first paragraph describes...

Transient Response of Guyed Telecommunication Towers Subjected to Cable Ice-Shedding
This paper presents the results of a numerical study of the transient response of guyed telecommunication towers subjected to sudden ice shedding from the guy wires. Detailed nonlinear...

Design for Durability for Large Reinforced Concrete Shells
Classical design concepts restrict themselves to sufficient structural safety, using linear analysis methods. Durability questions are mainly treated independently. Modern computer simulations...

Some Applications of Neural Networks in Structural Engineering
After a brief discussion of neural networks and their potential engineering applications, the author's on-going research in application of neural networks in structural engineering will...

General Structure Representation for Neural Networks
Current applications of neural networks for structural analysis are limited to specific structures. In order to expand the use of neural networks to general structural types, the input...

Damage Tolerance Analysis in Structural Rehabilitation
The rehabilitation of existing structures requires an evaluation by the structural engineer of past performance to determine the extent of existing damage. Following evaluation of the...

Distributed Flexibility Models for Nonlinear Analysis of RC Structures
