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...

A Generalized Approach to the Local Stability of Stiffened Plates: Part I?Mathematical Formulation
The paper describes a generalized approach for the determination of the buckling stress of stiffened plates under combination of uniform biaxial compression, in-plane bending and shear...

A Generalized Approach to the Local Stability of Stiffened Plates: Part II?Approximate Solution
The paper presents an approximate solution for the prediction of the buckling stress of stiffened plates under combined loadings. A closed form expression is presented for the buckling...

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...

Non-Linear Solution Methods for Shell and Spatial Structures
Non-linear solution methods are investigated for the analysis of shell and spatial structures based on limited memory quasi-Newton updates. Under the proposed implementation the preconditioned...

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...

Analysis and Design of a Double Layer Barrel Vault with a Large Span
The roof of coal storage in JiaXin Power Station is a double-layer barrel vault. This roof covers span of 103.5 M and a longitudinal span of 88.0 M. The height of this space truss is 3.5...

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...
