Study on Design Method of Joint Panels for Hybrid Railway Rigid-frame Bridges

Intelligent Software for Railway Bridges Design

The Computer aided design software have not been used as extensively by the profession as the computer aided analysis software due to the inability of these software to capture the complex process of design, which is an open ended problem. Whereas human designers, using their intelligence, domain knowledge, experience, common sense and ability to continuously learn, have been able to solve such...

A Parametric Study: Frame Analysis Method for Masonry Arch Bridges

The predictability of masonry arch bridges and their behaviour is widely considered doubtful due to the lack of knowledge about the conditions of a given masonry arch bridge. The assessment methods for masonry arch bridges are MEXE, ARCHIE, RING and Frame Analysis Method. The material properties of the masonry and fill material are extremely difficult to determine accurately. Consequently, it i...

HYBRID PARTICLE SWARM OPTIMIZATION, GRID SEARCH METHOD AND UNIVARIATE METHOD TO OPTIMALLY DESIGN STEEL FRAME STRUCTURES

This paper combines particle swarm optimization, grid search method and univariate method as a general optimization approach for any type of problems emphasizing on optimum design of steel frame structures. The new algorithm is denoted as the GSU-PSO. This method attempts to decrease the search space and only searches the space near the optimum point. To achieve this aim, the whole search space...

Comparison of Design Standards for Steel Railway Bridges

The popularity of steel bridges is increasing in the modern era because of its unmatchable advantages. Engineers are using various national codes to achieve an optimum design. Some of the Asian countries are using their own codes and also American and other country code provisions to achieve better economy and better standards. In this regard the comparison of design codes is relevant. Comparis...
