A Shape Annealing Approach to Creative Design of Structures
This paper shows how shape grammars can be used to model structural engineering problems. The shape annealing algorithm is then used to synthesize component topologies by bringing analysis...
Computer-Supported Creative Structural Design
In this paper, a model for creative engineering design using a network-based design prototype representation and a mutation technique is presented. The model distinguishes between a domain-dependent...
Optimal Adaptive and Predictive Control System of Buildings by Neural Network and Fuzzy Theory
This paper describes an optimal adaptive and predictive control system and its digital simulations for a single-degree-of-freedom system subjected to earthquake loading. In this system,...
Verification of Real-Time Software for Active Structural Control
In this paper we give an overview of our preliminary work in verifying the reliability of real-time software systems for active structural control. While there have been numerous studies...
Simulative Calculation of Highrise Building Structure Under Vertical Loads
It is well known, the general structural stiffness and the vertical construction loads are formed storey by storey from bottom to top of the building especially for cast R.C. structure....
Parallel-Adaptive Finite Element Analysis on a Transputer Cluster
This paper describes a parallel-adaptive finite element approach on a parallel transputer cluster of the MIMD type. The analysis is controlled by a special error indicator. In comparison...
Secondary Member Contribution to the Behavior of Damaged Multigirder Highway Bridges
This paper examines the effects of secondary members (cross bracing and diaphragms) on the prediction of the response of damaged simple span steel multigirder bridges. Extensive analytical...
The Influence of Preform on the Vibration Mode of a Thin Plate
In this paper, an algorithm is developed for the calculation of the vibration mode of a preformed thin plate. The principal governing equations are derived by using the large-deflection...
The Reliability Program in Truncated JC Method
JC method is in common use in the structure reliability analysis. In this paper, the program which can be used as to consider the truncated distribution has been proposed, With this method...
Rive, Rive-Grown and Burst Probability of Rolled Compressive Concrete Arch Dam
The rive, every step of the rive grown and even burst of arch dam are regarded as sequence random events. Making use of the probability theory and the achievement of elastic, elastic-plastic...
The Application of Gauss Numerical Integration Method in Arch Dam Trial-load Method Program
The characteristics of Gauss Numerical Integration Method are the unequal distance between nodes and fairly high accuracy. When the number of nodes is n, the algebraic accuracy can be...
After the Blast
On February 26, 1993, a bomb exploded in an underground parking garage beneath the World Trade Center, killing six, causing hundreds of millions of dollars in damage and leaving a crater...
Nondestructive Evaluation Techniques and Their Role in Infrastructure Management
Nondestructive evaluation (NDE) techniques can play an important role in infrastructure management. They can be used to assess current condition a well as to predict future performance...
Sonic NDT for Infrastructure Assessment
Sonic Nondestructive Testing (NDT) techniques are valuable tools for assessing infrastructure. Relatively recent innovations in the field can reveal the internal conditions of concrete...
How to Get Local Public Works Agencies to Use Structured Infrastructure Management Approaches
As more agencies consider adopting infrastructure management systems, the lessons learned in developing and supporting the use of current systems should be used to structure the support...
Modeling the Spatial Structure of Facility Condition
This study develops methods for information extraction that he bridge the gap between the detailed condition data collected by advanced technologies and the information necessary for maintenance...
Corrosion Model for Concrete Structures
The high basic environment created by concrete pore water protects the reinforcing steel from spontaneously corroding. Chloride ions destroy the passivity of steel in concrete and the...
A Condition Rating System for Rubble Breakwaters and Jetties
This paper describes one aspect of a series of projects which the U.S. Army Corps of Engineering has undertaken in an effort to improve maintenance management of coastal and navigational...
Using Condition Indexes to Evaluate Local Railroad Track Networks
The U.S. Army Construction Engineering Laboratories (USACERL) have developed condition indexes for assessing track condition that apply to local railroads. Indexes were developed for the...
Highway Maintenance and Integrated Management Systems
Maintenance management systems were among the first applications of rational management principles and the (then) the new technology of computers to highway operations. Recent changes...
