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)

Synopsis:

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.

空腹夾層板樓蓋是由空腹梁（混凝土、鋼、鋼-混組合）交叉形成的抗剪剛度很大的夾層板。當它與網格式鋼架牆剛性連接後，形成空間網格盒式結構，這是馬克儉教授獨創的具有中國自主智慧財產權的新型結構體系。從上世紀90年代中期至今，已在各類建築工程應用，面積達到250萬平方米以上，遍及中國大陸23個省、市及自治區，它們分別是：

1）多層（2層~4層）、大跨度（18m~39m）公共與工業建築；

2）小高層、高層大開間、靈活劃分居室的節能住宅建築；

3）高層及超高層大空間、靈活劃分房間的多功能、綜合應用寫字樓建築

報告將分別介紹此類新型結構的組成與構造要求，其靜、動力特性；通過各類工程實踐與傳統結構的對比分析，論證新型結構體系在當今社會的發展潛力。

About Speaker:

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.

馬克儉院士，現任貴州大學空間結構研究中心主任。長期以來，在建築結構工程領域裡堅持自主創新，首創混凝土、鋼、鋼-混凝土組合的空腹網架、空腹夾層板等多層大跨度樓蓋結構，首次提出大跨度與超大跨度預應力組合扭網殼結構，並成功應用于多項體育建築工程。在空腹網格擬夾芯板理論基礎上，提出空間網格盒式結構新體系，該體系填補了國內外空白。以主持人身份獲國家科技進步三等獎一項、貴州省科技進步一等獎兩項、二等獎兩項、三等獎六項，部級（建設部、鋼協）科技進步二等獎兩項，全國發明競賽一等獎兩項、香港孺子牛金球獎一項、發明專利100多項，出版著作及規程六本。2013年獲中國建築學會成立六十周年頒發的突出貢獻獎、獲中國鋼結構協會頒發終身成就獎；2014年獲“中國鋼結構三十年領軍人物”稱號；2016年榮獲中央九三頒發的“九三楷模”榮譽稱號；2017年中國鋼協最高成就獎。
