Liu first introduced the research progress of the architectural design method of small section wood frame, the mechanical performance test of materials and components, the calculation method of wall stiffness and the structural design method, and then introduced the research and development progress of steel strap support of fast-growing wood frame structure, wood-concrete composite floor and key installation technologies, and finally introduced the demonstration projects and key technologies of these two structural systems, It provides two low carbon and environmental protection structural systems for rural housing construction.

Mr.

Performance, Monitoring and Evaluation of Wood Structures in Ancient Buildings, President Yang Qingshan made a report entitled “Performance, Monitoring and Evaluation of Wood Structures in Ancient Buildings”.

The meeting was presided over by Zhou Ting, Deputy Secretary-General of Tianjin Institute of Steel Structures/Associate Professor of Tianjin University.

The report introduces the research progress from five aspects, namely, the indoor and outdoor design calculation conditions of islands and reefs in the South China Sea, the thermal physical parameters and structure of island and reef building envelope, the thermal design principles and methods of ultra low energy buildings, modular photovoltaic systems suitable for islands and reefs in the South China Sea, architectural scheme creation and engineering demonstration.

Professor Chen Zhihua expressed sincere gratitude to the participants, and then entered the meeting report.

Through the application of project results, the residential comfort of villages and towns in cold regions has been greatly improved..

It is an urgent need to improve the rural living environment and build livable and beautiful villages to implement the “rural revitalization” strategy.

Aiming at the problems of unclear seismic mechanism of ancient buildings, difficult evaluation of safety status and difficult layout of monitoring system, he studied the basic performance of wood structures, and proposed a simplified model for analysis of joints such as mortise and tenon, column foundation and dougong, The principle of excellent seismic performance of ancient wooden structures was revealed, and the monitoring system was developed.

On January 9, 2023, the technical exchange meeting for precast buildings in eco-friendly, green and livable villages and towns was successfully held through online conference.

General Manager Liu Yifeng worked on the report entitled “Research and Engineering Demonstration of New Village and Town Wood Structure Residential System”, and proposed two kinds of wood structure systems suitable for rural areas.

The research results also provide technical support for the evaluation and restoration of a large number of existing wooden structures in rural areas.

At present, the development of vast villages and towns in China is unbalanced and inadequate.

Research on Bamboo (Wood) Structure Houses Professor Xiao Yan made a report entitled “Research on Bamboo (Wood) Structure Houses”, proposing that the construction of villages and towns should retain the local conditions and build modern village and town buildings with regional culture and local materials.

In China’s 14th Five-Year Plan and the 2035 long-term goal outline, it is clearly pointed out that we should take the path of socialist rural revitalization with Chinese characteristics and comprehensively implement the rural revitalization strategy.

Professor Xiao first shared the construction of demonstration projects supported by national and local projects such as the national key research and development plan, and then introduced the latest research results of new bamboo materials, bamboo components and bamboo structures such as GluBam glued bamboo structure, nailed bamboo structure (NLB) and orthogonally glued bamboo and wood, and studied the thermal performance and comfort of the wall, providing theoretical basis and practical support for the design and construction of bamboo structure residential buildings in villages and towns.

The conference invited Liu Jiaping, an academician of the CAE Member/professor of Xi’an University of Architecture and Technology/director of the State Key Laboratory of Green Building in Western China, Liu Yifeng, a master of engineering survey and design in Sichuan Province/deputy chief engineer of China Southwest Design and Research Institute Co., Ltd., Xiao Yan, a professor of Qiushi, Zhejiang University, and Yang Qingshan, a national outstanding youth/Yangtze River scholar/dean of the School of Civil Engineering, Chongqing University Wu Yue, vice president of the School of Civil Engineering of Harbin University of Technology, and Chen Zhihua, president of the Tianjin Institute of Steel Structures/vice president of Tianjin University of Urban Construction/chair professor of Tianjin University, conducted the technical report and sharing of precast buildings in ecological, green and livable villages and towns.

After the meeting began, the host, Deputy Secretary-General Zhou Ting, introduced the participants.

According to the thermal and humid environment characteristics and energy characteristics of the Nansha Islands, a strategic area in China, suitable ultra low energy consumption buildings were studied.

Ultra low energy consumption buildings in extreme hot and humid climates Academician Liu Jiaping made a report entitled Ultra low energy consumption buildings in extreme hot and humid climates.

Lifting Eye

was introduced.

Professor Wu Yue, the key technology of multi-dimensional evaluation and optimization of green performance of rural housing, made a report entitled “Key technology of multi-dimensional evaluation and optimization of green performance of rural housing”, introducing the research content of the fourth subject (2019YFD1101004) in the “13th Five-Year Plan” national key research and development project “Research on ecological structural system of precast housing in villages and towns”, mainly introducing the research results of green performance evaluation and optimization, It includes the survey of residential conditions in villages and towns, the design and optimization technology of energy conservation and carbon reduction in villages and towns, the evaluation method and demonstration project of indoor environmental comfort in villages and towns, and the application of comprehensive technology.

The research results have greatly improved the comfort of residential buildings in the the Nansha Islands, and made a significant contribution to maintaining national marine territorial security.

Finally, the application of the above achievements in ancient buildings such as Potala Palace, Pingyao Confucian Temple Dacheng Hall, Wanrong Feiyun Building, etc.

In order to further promote the improvement of disaster prevention capacity and environment of village and town housing, and promote the training of professionals in relevant disciplines, Tianjin Institute of Steel Structures and Tianjin University, with the support of academicians’ academic activities of the two academies of the Tianjin Association for Science and Technology, organized and held the “Technical Exchange Conference on Ecological, Green and livable precast buildings in villages and towns”.
