(Supported by Structural Division)


Scope and Objectives

This workshop is supported by PASS for promotion of practical design guidance for engineers using the new design method – Direct Analysis (DA) which will be explained in a simple and practical manner in the lecture with practical examples given and real case studies provided. The lecture note will be related to “Code of practice for the structural use of steel 2011” published by Buildings Department of SAR Government and in many other national codes such as the AISC360 (2016) in USA, Eurocode-3(2005) and GB 50017(2017). To date, it is common to require engineers to design a structure safely and reliably as well as economically by the new DA design technique since critical structural elements will not under-sized and redundant member not over-sized. When using the old and traditional First-order Linear Analysis or Effective Length Method (ELM), the size of structural elements are inappropriately proportioned and sized. The application of direct analysis in conjunction with the new wind code 2019 will also be discussed in the end part of the seminar using a self-generating software Nida-Wind 2020. This lecture will discuss the 3 analysis methods accepted in design codes in Hong Kong and other codes, namely as the linear analysis with effective length method, second-order Indirect analysis (or the P-D-only analysis in HK and AISC code) and the Second-order Direct analysis P-D-d analysis. Theory and applications of these methods will be explained with illustrations by practical project applications. Other applications including use with new local wind code will be described. In parallel with face-to-face presentation, online lecture will be arranged with use of webinar online. Successfully online registered participants will be emailed a link for webinar. Question and Answer sessions are available. CPD certificates will be issued to attendants with successful online and face-two-face registration.



Professor Siu Lai Chan is the chief and founding editor of the SCI-e international journals “Advanced Steel Construction (”, “Steel and Composite Structures (2002-2005)” and the regional editor of “International Journal of Applied Mechanics and Engineering”, a member of editorial boards in 7 other journals, the principal consultant of design codes for steel and glass structures in Hong Kong and an adjunct professor at the Southeast University in Nanjing, Harbin Institute of Technology in Harbin and Tongji University in Shanghai. In conjunction with a research team of the Tongji University, he received the first class award for research by the Education Ministry in the Mainland China, research awards by the Structural and the Geotechnical Divisions of HKIE in the same year of 2016 and in Research Grand Award by Structural Division HKIE this year 2020. He also served as the Chairman of the Structural Division HKIE in 2013, of the Structural Discipline in 2017-2019 and Deputy Chairman of Fire Division HKIE in 2016 and he is also a member of board in Chinese national steel code GB50017 (2017). His research in nonlinear analysis has been over 3 decades with several hundred papers published and numerous lectures delivered, including one-day workshop at Imperial College U.K. in 2015 and in National Singapore University on applications of nonlinear analysis to practical design.


Dr. Y.P. Liu received his BEng from Sun Tat Sen university and now he is the director of NIDA Technology Co., Ltd. He obtained his PhD degree from the Hong Kong Polytechnic University and his research interests include development of finite elements; second-order direct analysis and design of steel and composite structures, long-span steel structures and computer applications related to structural engineering. Dr. Liu is a Guest Professor at Southwest Jiaotong University (西南交通大學) and Shenyang Jianzhu University (瀋陽建築大學) and he also serves as an associate editor of the SCI-e International Journal “Advanced Steel Construction” and “Progress in Steel Building Structures” (建築鋼結構進展). Dr. Liu made significant contributions on the drafting work of the new Chinese Steel Code “GB50017-2017” and provides numerous engineering consultancy services for design of numerous large-scale steel structures in Hong Kong, Macau, Singapore, India and Myanmar, including the world longest steel roof archived in Guinness record 2019 with a reporting paper “Design and construction of long-span single-layer dome structures by direct analysis”, HKIE Transactions, 25:1, pp. 29-43, 2018, DOI: 10.1080/1023697X.2017.1409663.


Dr. Jerry Iu received his BEng and PhD at PolyU and he is currently a research Fellow at PolyU and worked before as a lecture in Queensland University of Technology, Australia, a research fellow in University of New south Wales Australia, Graduate school in Harbin Institute of Technology, China and University of Hawaii USA. He has published some 30 journal papers and 40 conference papers. With two years as a structural engineer in a consultant, Dr. Iu has a good and balanced background in research and engineering design. Recently, he worked on research and practical projects related to Direct Analysis.
