Date, time & venue
2018-11-21;6:00 pm – 6:30 pm (Refreshment), 6:30 pm – 8:15 pm (Talk);Chan Yat Mei Sophie Room – 9/F
Speakers: Professor Ma Kejian, Academician of Chinese Academy of Engineering (馬克儉 教授 中國工程院院士)
The open-web sandwich slab is a kind of sandwich slabs with large shear rigidity, which are formed by the intersection of open-web beams made of RC, section steel or steel-concrete composite. When it is rigidly connected with grid steel frame wall, a spatial grid box structure is formed, which is a new structural system that proposed by Professor Ma Kejian. Since the middle 1990s, the new structural system has been applied in various projects with a construction area of more than 2.5 million square meters, covering 23 provinces, municipalities and autonomous regions in the mainland of China. Its applications can be divided into three categories:
1) Multi-storey (2 ~4 storeys), large-span (18m~39m) public and industrial buildings;
2) Energy saving residential buildings which are small high-rise buildings with large open and flexible division rooms;
3) High-rise and super high-rise buildings with large space, flexible multi-functional rooms and comprehensive application office.
In the seminar, Professor Ma Kejian will introduce the composition and structural requirements of the new structure as well as its static and dynamic characteristics, and demonstrate the development potential of the new structural system in today’s society by comparing various engineering practices with traditional structures.
Professor Ma Kejian is the director of Space Structures Research Center of Guizhou University. Over the years, he insisted on independent innovation in the field of structural engineering and pioneered multi-storey and long-span floor structures, such as RC, sectional steel or steel-concrete composite open-web spatial truss, open-web sandwich slab, and so on. He firstly proposed long-span and super-long-span composite torsional reticulated shell structure, and successfully applied it in many sports buildings. Based on the theory of hollow grid quasi-sandwich panel, a new spatial grid box structure system was proposed, which filled the blank both at home and abroad. He won a third prize of National Science and Technology Progress Award, two first prizes and one second prize of Guizhou Province Science and Technology Progress Award, and six third prizes of Guizhou Province Science and Technology Progress Award. He obtained two second prizes of Ministerial-Level (the Ministry of Construction, Steel Association) Science and Technology Progress Award, two first prizes of National Invention Contest, and a Hong Kong Golden Bull Award. He owns more than 100 Invention Patents and publishes six books and specifications. He was awarded the Outstanding Contribution Award by the Chinese Architectural Society and the Lifetime Achievement Award by the Chinese Steel Structure Association in 2013, the “Leader of the Chinese Steel Structure in 30 years” title in 2014, the “93 Model” honorary title awarded by the Central Committee in 2016, and the Highest Achievement Award by the Chinese Steel Association in 2017.
The seminar will be conducted in mandarin.
