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....

Computer Assisted Conceptual Structural Design of Steel Buildings
The design quality of a building is mostly determined during the conceptual design stage. Computers, however, have not been used effectively to handle the conceptual design of building...

Three-Dimensional Nonlinear Analysis of a Wooden Structure with Base Subsidence
A heavy rain caused a famous Chinese ancient wooden structure to suffer serious base subsidence. In order to deal with the base subsidence of the valuable structure, a joggle model and...

Numerical Analysis of Membrane Action in Hollow Core Floors
The emphasis of the investigation is on the diaphragm action of precast floor structures. In order to improve existing manual calculation methods a parameter study has been carried out...

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...

Decision Methods for Selecting Earth Retaining Structures
The Bridge Branch of the Colorado Department of Transportation (CDOT) has organized the framework of a formal decision process for retaining wall selection. The process facilitates implementation...
