DESCRIPTION:Dr. Lan Duan\nCompared with conventional steels used in bridge
  construction\, high performance steel (HPS) has superior properties in te
 rms of strength\, weld ability\, fracture toughness and weathering charact
 eristics. These material properties lead to very competitive costs and low
  carbon release in the whole life span of HPS bridges. This presentation f
 ocuses on the high performance steel HPS 485W\, with a nominal yield stren
 gth of 485MPa. Studies are conducted on fracture control\, fatigue resista
 nce design\, fabrication technology\, structural strength and stability. W
 ith respect to fracture control and fatigue design\, experimental campaign
 s were conducted\, comprising impact toughness (CVN) tests\, ductile fract
 ure toughness (JIC) tests\, crack tip opening displacement (CTOD) tests an
 d fatigue crack growth rate (da/dN) tests. In addition\, the flexural and 
 shear behavior of hybrid high performance steel beams were investigated by
  means of experimental tests\, finite element calculations and theoretical
  analyses. The study addresses the HPS beam’s capacity\, ductility\, fai
 lure mode and stability behavior. Based on these research results\, the co
 sts and performance of high performance steel plate girder bridges and tra
 ditional steel plate girder bridges are compared.\nBio: Lan Duan is a lect
 urer at the Bridge Engineering Institute\, Highway School\, Chang’an Uni
 versity in China. She received her Ph.D. in Civil Engineering from Chang
 ’an University in China. Lan Duan works research focuses on high perform
 ance steel bridges\, fatigue and fracture of steel bridges\, and steel-con
 crete composite bridges. She has participated in the following research pr
 ograms: “Static and fatigue behavior study for high performance steel st
 ructure”\, “Key technology study for high strength steel bridge”\, 
 “Capacity and remaining life calculation for old steel bridge” and “
 Orthotropic steel bridge deck fatigue mechanics and remaining fatigue life
  evaluation study”.
