DESCRIPTION:Professor Xiaodong Ji\, Associate Professor Department of Civ
 il Engineering\, Tsinghua University 30 Shuangqing Rd\, Haidian\, Beijing
 \, China\nABSTRACT\nOver the past two decades\, large numbers of high-rise
  buildings have been constructed in modern cities of China. High seismicit
 y often leads to serious challenge to design and construction of high-rise
  buildings. Innovative structural components and systems\, which adopt the
  composite and hybrid concept\, have been recently developed for enhanced 
 seismic performance and resiliency of high-rise buildings. This presentati
 on will provide a brief overview of novel types of composite columns and c
 omposite shear walls\, which have seen increasing use in building construc
 tions in China. Moreover\, this presentation will particularly introduce a
  new type of hybrid coupled wall system consisting of replaceable steel co
 upling beams (RSCBs) and RC wall piers. While traditional RC coupling beam
 s\, if detailed appropriately show adequate seismic performance\, once dam
 aged\, these components are expensive and time-consuming to repair. As an 
 alternative to RC coupling beams\, the replaceable steel coupling beam is 
 proposed\, which comprises of a central “fuse” shear link connected to
  steel beam segments at its two ends. By appropriately proportioning the e
 lements\, inelastic deformation is concentrated in the shear link during a
  severe earthquake\, and the link can be replaced readily after being dama
 ged as specialized link-to-beam connections are adopted. This presentation
  will introduce the design method and recommendations for the proposed RSC
 Bs\, which are backed up by a series of large-scale tests. In addition\, s
 eismic performance of the hybrid coupled wall system with RSCBs is assesse
 d using a recently developed method recommended in FEMA P-58. The performa
 nce of the hybrid coupled wall system is benchmarked against the tradition
 al reinforced concrete coupled wall\, and the results imply the improved r
 esiliency of the proposed hybrid coupled wall system.\nAbout the speaker\n
 Dr. Xiaodong JI is an associate professor at Department of Civil Engineeri
 ng\, Tsinghua University. He received his B.E. and Ph.D. of Civil Engineer
 ing with distinction from Tsinghua University in 2002 and 2007. Prior to h
 is appointment at Tsinghua University in November 2009\, he was a JSPS Pos
 tdoctoral Researcher at Kyoto University in Japan. Currently\, he serves a
 s Assistant Dean of School of Civil Engineering and Vice Director of the I
 nstitute of Disaster Prevention and Mitigation Engineering\, Tsinghua Univ
 ersity. Dr. Ji’s research focuses on development of high-performance str
 uctural components and innovative systems for enhanced seismic performance
  and resiliency of building structures. He is also engaged in developing a
 dvanced dynamic testing methods and structural monitoring technologies\, w
 ith the scope of achieving realistic simulation and observation for seismi
 c behavior of structural systems. He has extensive experience with large-s
 cale tests of structural components and full-scale shaking table tests of 
 building structures. He has published over 100 referred journal papers and
  conference papers. Dr. Ji’s research outcomes have been applied in a nu
 mber of projects of super-tall buildings and large-scale infrastructures i
 n China. He has served as the committee members for drafting several desig
 n codes\, specifications and guidelines. He has won the National Science a
 nd Technology Progress Award (Second Prize) and the Best Teaching Award of
  Tsinghua University.
