Since the 21st century, wood as a renewable green building materials, wood structure building as a sustainable development building has obvious advantages, domestic research institutions to carry out research on wood structure is also more and more, wood structure design and construction technology has been rapidly improved, the standard system is also gradually improved; at the same time, the country also issued relevant policies to support prefabricated, green wood structure building, China’s wood structure ushered in a new era This is a new period of development opportunities
. 
In April 2020, “building structure” summarizes the standards, development process, design and research results of wood and bamboo structure in detail
. 
See “dry goods of building structure” for the content! The most comprehensive collection of wood structure design, take it away! From October 14 to 15, 2020, “the third wood bamboo structure design forum” was successfully held in Chengdu
. 
Now, the wonderful report videos and the latest wood bamboo structure articles published in the magazine will be collected for your study and collection

Discussion on the design idea of large span steel wood composite structure based on the engineering characteristics of Glulam Introduction of national timber structure standard and research work to be carried out introduction of longweiguo No.6 “technical standard for multi story and high rise timber structure” and development trend of multi story and high rise timber structure Yang Xuebing No.7 comparison of reliability analysis of timber structure between China and Canada Zhu enzhun No.8 seismic performance of prestressed orthogonal Glulam shear wall structure he Minjuan No.9 seismic technology research and engineering application of multi story and high rise timber structure Study on the determination of the design index of Weidong No.10 imported Glulam the research progress of the bamboo structure design value and method of eurocana No.11 project The future Construction Liu Jie excellent article No.1 the stiffness analysis of typical tenon mortise joint of wood structure building Kuang Yanyi No.2 experimental research on bending performance of structural bamboo Click here to view the full text of the report
. 
The main contents are as follows: firstly, it introduces the long-term work of China Southwest Institute of construction in compiling relevant specifications of wood structure, so as to lay a good foundation for the application of wood structure
. 
Then, combined with typical engineering cases, such as Qingdao natatorium, Chengdu Xinjin water city exhibition hall, Qingdao Jiaodong International Airport Terminal corridor, Zhengzhou Olympic Sports Center Natatorium, Sichuan Airlines activity center, Leshan Olympic Sports Center Natatorium, Xinjiang Shihezi natatorium and many other projects, this paper expounds the unremitting efforts of China Southwest Institute of construction in the long-span Glulam space structure from 2006 to 2020, Persistent exploration
. 
After 14 years of continuous efforts, it was finally affirmed: the successful application of large-span Glulam roof system in “Sichuan Airlines activity center” and “Xinjiang Shihezi swimming pool” projects
. 
Based on the engineering characteristics of Glulam, this paper discusses the design idea of steel wood long-span structure

. 
Main content: the report starts with the introduction of the production method of Glulam materials, expounds the engineering characteristics of Glulam, compares it with concrete and steel, and discusses the application of Glulam materials The mechanical properties and joint connection characteristics of Glulam structural members under the different material properties
. 
Furthermore, it introduces the reasonable and appropriate structural system and design strategy in the layout of long-span structure due to the unique engineering characteristics and joint connection characteristics of Glulam, and also illustrates the importance of coordination between structure and component design

. 
Main content: the report gives a brief introduction to Chengdu Jincheng Plaza from the aspects of project overview, design basis, load value, seismic performance target, roof structure scheme and calculation and analysis results In this paper, the design and research of the large span steel wood composite structure of Chengcheng square are introduced in detail
. 
Among them, through the comparative analysis of the roof material, the joint stiffness of the wood arch, the support node of the steel structure and the arch foot node, the reasonable and efficient structural calculation and analysis model is determined that the lower chord cross wood arch is the main stress component, and the web member and the upper chord member adopt the circular steel pipe
. 
The static analysis, dynamic analysis, stability analysis, progressive collapse resistance performance analysis, fire resistance analysis and key node analysis of the roof structure show that the long-span steel wood composite structure roof is safe and reliable, and has good overall stability and seismic performance
. 
Main contents: the report first introduces the design background of “cloud in Pavilion”, that is, “cloud in Pavilion” is located in Beijing The campus of Forestry University is a bamboo Pavilion designed for the “Bamboo Landscape Garden Festival”
. 
Then it elaborates the investigation of people flow and service crowd in the early stage and the arrangement of the site
. 
Finally, it deeply introduces the concept design concept of “cloud in Pavilion”, the challenges encountered in the design and construction and the solutions
. 
The completed “cloud in Pavilion” integrates structure, acoustics, optics and environmental behavior, and serves as a venue for the opening, closing, awarding and various activities of the “Bamboo Garden Festival”
. 
This building has won the “Engineering Design Award” of the World Architecture Festival 2019waf

Introduction of China’s wood structure standards and research work to be carried out long Weiguo, Secretary of the Party committee and chairman of China Southwest Architectural Design and Research Institute Co., Ltd., chairman of the wood and composite structure Professional Committee of China Engineering Construction Standardization Association (click on the picture to view the video) main contents: firstly, the characteristics of China’s wood structure standard system are introduced, and the “wood structure design” is introduced In this paper, some important wood structure standards, such as standard, technical specification for Glulam structure, are systematically elaborated
. 
Then, the further research work of China’s wood structure standard is discussed from the aspects of wood strength grade, application of new engineering wood products, connection, calculation of wood composite members, application of large span / multi-storey wood structure, etc
. 
Finally, an example is given to illustrate the wood structure standard The application prospect of the structure in large-span public buildings, urban renewal, cultural and tourism convalescence and rural construction in China
. 
06 introduction of China’s “technical standard for multi story and high rise timber structure” and development trend of multi story and high rise timber structure This paper introduces the main technical contents of structural building technical standard (GB / t51226-2017), and makes a detailed analysis of some technical contents
. 
Third, the development trend of foreign multi-storey and high-rise wood structure buildings is described, and the current situation and future development trend of multi-storey and high-rise wood structure buildings in China’s engineering construction are discussed and analyzed.
