A DESIGN METHOD OF BEAM-TO-COLUMN INSERT JOINT FOR HYBRID RAILWAY RIGID FRAME ELEVATED BRIDGES

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

Finite element analysis of a rigid beam to column connection reinforced with channels

Abstract: This research work presents a new rigid connection constructed with channels. In order to assess its hysteresis behavior, three specimens with different cover plates and six specimens with different panel zone thickness have been considered. The energy absorbed by the connection and the behavior of the panel zone were studied during cyclic loading and compared with those of connectio...

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...

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...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
