In this paper, we present a method for extracting center axis representations of tubular shapes obtained from medical images. The method extracts centerlines by computing minimum-cost paths from a graph based optimization algorithm which minimizes responses obtained from multi-scale medialness filters. These filters are designed from the assumption that tubular structures, in general, has circu...

Abstract Due to high bearing capacity and excellent seismic performance, the section steel reinforced concrete-filled rectangular tube has been widely applied in engineering. The application of stainless for outer can improve durability performance members. In this study, ABAQUS software was used perform nonlinear analysis on tubular columns, numerical model validated against experimental data....

This paper aims to experimentally study the fire performance of steel-reinforced concrete-filled steel tubular (SRCFST) columns without protection. Eight SRCFST specimens with cruciform section profiled were tested under ISO-834 standard fire. The various test parameters including cross-section type tube (circular or square), load ratio and eccentricity considered discussed. temperature distrib...

Manufacturing execution system (MES) is a bridge that connects the top layer of planning and the bottom layer of control. In integrated automation system (IAS) whose structure is 3-layer BPS/MES/PCS, MES is the key circle to realize the integrating of integrated automation system in iron & steel enterprise. According to the characteristics of production management in iron & steel enterprise, th...

Aiming at the large deformation problem of U type steel support for the roadway in deep high stress soft rock, By means of theoretic analysis and digital imitation, study on U type steel support for soft Rock Roadway. A u shaped steel & anchor rope combined supporting structure was put forward ,with the help of numerical simulation analyzing the structural, results show that the structure contr...
