Computer Methods Used on Seismic Retrofit Projects
Over a relatively short period of about twenty years, personal computers (PC's) have replaced slide rules in most engineering calculations. PC's are now staple equipment in every engineering...
Qualitative Formulation of Load Paths Through a Functional Description of Structures
The past few decades have seen major advances in computer tools to analyze complex structures and loadings. For the most part, these programs have focused on two areas - A, programs for...
A Constraint-Based Composites Design Advisor
Most engineering problems, because they involve mathematical relations (constraints) on real valued quantities (objects), can be reduced to constraint networks. The authors speculate that...
Crack and Contact Problems in Masonry Arch Bridges
A two-dimensional finite element program has been developed to predict the load carrying capacity of masonry arch bridges with different structural defects such as missing bricks and tangential...
Stress Analysis in Concrete with Cooling Pipes
A substructure method of finite element analysis is adopted in this paper to simulate heat transfer and thermal stresses in a concrete dam. The massive concrete structure is cooled by...
PDS: An Expert System for Distress Diagnosis of Flexible Pavements in Taiwan
Pavement distress diagnosis requires a significant amount of engineering judgement which is difficult, if not impossible, to be quantified. This is an excellent domain for the development...
An Application of Neural Networks to Hysteretic Modeling of Steel Structures
This paper describes an application of the neural networks to realistic hysteretic modeling. The neural networks learn from sample data (training cases) and make predictions for new cases....
Non-linear Analysis of a Cable Stayed Bridge
A concrete single-pylon cable-stayed bridge has been analyzed to investigate the ultimate capacity. Two different methods were used to investigate the nonlinear behaviour. First, a simplified...
Optimal Seismic Design of Structures

Computer-Aided Guyed Tower Analysis for the Rehabilitation of TTI Tower, Baltimore
A large guyed television tower owned by Television Tower Inc. of Baltimore is currently being analyzed in order to evaluate the capacity of the tower to support additional broadcasting...
Deriving Alternative Structural Modifications Based on Qualitative Interpretation at the Conceptual Design Stage
Current computer tools provide little support in deriving alternative modifications based on qualitative structural interpretation of a conceptual design. This paper presents a behavior-based...
Reducing Ambiguity in Qualitative Reasoning
Qualitative reasoning derives the behavior of a physical system using a representation of the fundamental principles for the domain. In qualitative reasoning parameters are mapped into...
Evaluation Plan for AVL Implementations
The Federal Transit Administration, as part of the Advanced Public Transportation Systems program (a component of the Intelligent Vehicle-Highway Systems initiative), is conducting the...
A Numerical Procedure to Compute Bearing Capacity of Shallow Foundations
A simple numerical procedure of calculation of bearing capacity of shallow foundation is proposed. This procedure employs the Terzaghi-Prandtl model of general shear failure. In this paper,...
Regional Stress Field Due to Water-Filling at Sanxia Dam
This paper uses the observed stress values to simulate the tectonic stress field in the reservoir. Based on the increment analysis method. we discuss the effects and variations of the...
Computer Aided Experiments for Truss Structures
It is quite difficult to investigate structural mechanical properties by full scaled structure experiments. Consequently, an experiment using a reduced scale model is generally performed....
A Process to Enhance the Flow of Engineering and Management Information at Ford Hood, Texas
This paper describes a study of the information requirements at the DEH (Directorate of Engineering and Housing) at Fort Hood, Texas which was undertaken by the U. S. Army Corps of Engineers...
Nonlinear Trial Load Method of Arch Dams
The trial load method is still an important method for the stress analysis of arch dams at present. However, the trial load method can be used only for the linear elastic analysis of arch...
Foundation Uniform Pressure and Soil Structure Interaction
The enclosed paper was presented in the ASCE, 8th Conference on Computing in Civil Engineering and published in its proceedings. One of its main assumptions was considering the foundation...
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....
