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...

The Slender Tower of 52-54 East End Avenue
The structural system for the 52-54 East End Avenue project is presented. The 40 story residential tower with as aspect ratio of 12: 1 is one of the most slender buildings constructed...

Roof Space Frame Design of the C.K.S. Airport Passenger Terminal II
This article attempts to provide a description of the characteristics of the Second Terminal Airport. To comply with the functional requirement of the magnificent facade and spacious design...

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...

Dynamic Analysis of Unstable Structural Systems With Prescribed Velocities
Structural systems that have large inextentional deformation, or in other words, deformation without stain are called 'Unstable Structural Systems.' They include cable structures, membrane...

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...

Possibilities and Problems of Latticed Structures
Several fundamental aspects of space frames which are sometimes referred to as latticed structures are discussed. Terminology of the structural system is first considered. Special features...

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...

Explorations in Geodesic Forms
Geodesic forms constitute an important family of structural systems. The objective of the paper is to show how the concepts of a mathematical tool called formex algebra and its programming...

Collapse Behavior of Double-Layer Space Truss Grids with Member Buckling
The results of collapse tests of over twenty space truss grids with elastic buckling of members are reviewed. The space truss grids include three types, that is, square-on-square, square-on-diagonal...

Study on Mechanical Characteristics of Light-weight Complex Structure Composed of a Membrane and a Beam String Structure
This paper aims at studying a new type of Beam String Structure, in which a membrane is used as finishing material. This paper reports on the mechanical characteristics of this structure,...

Form Finding Numerical Methods for Tensegrity Systems
The rigidification of Tensegrity Systems is related to selfstress states which can be achieved only when geometrical and mechanical requirements are simultaneously satisfied. This paper...

Innovations in Major Suspension Bridge Design
Before the Tacoma disaster, the trend in bridge-building is on increasing slenderness. But since its occurrence, a high degree of aerodynamic stability is required. Presented are designs...

Morphology of Reciprocal Frame Three-Dimensional Grillage Structures
This paper is an introduction to the morphology of structures using the Reciprocal Frame (also known as Mandala Dach in Germany) which is a patented three-dimensional beam grillage structural...

Integrated Research for Civil Infrastructure Systems: A Future Challenge
The paper presents a research program developed at NSF for the improvement and renewal of the nation's civil infrastructure systems. The proposed program is integrated, multi-disciplinary,...

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...

Multimedia Implications to Structural Engineering
The usage of computer technologies have revolutionized the practice of structural engineering during the past thirty years. The advent of multimedia technologies within computer hardware...

Large-Scale Computations in Analysis of Structures
Computer hardware and numerical analysis algorithms have progressed to a point where many engineering organizations and universities can perform nonlinear analyses on a routine basis....

An Automated Environment for Parallel Computing
Research on a prototype concurrent software development environment for large-scale structural engineering computing is currently underway at Purdue University. This environment is being...

Timing Analysis of a Multiprocessor Architecture for Active Control
This paper describes how real-time multiprocessor systems, such as those required for active structural control, can be developed to satisfy timing requirements on hardware and software....
