He has presided over and participated in the scientific and technological innovation project of Guangdong Provincial Department of Education-Research on Seismic Performance of New Hybrid Structure of Steel Frame-Steel Reinforced Concrete Shear Wall (212KJCX84, moderator), and the Tenth Five-Year Plan Project of Guangdong Provincial Department of Education (GYA251, moderator, identified, Guangdong Provincial Department of Education CertificateNo. 252JT13), Design Principle of Steel-Concrete Composite Structure-Project initiated by China Academy of Sciences (Teaching Material Construction Expert Committee) (provincial and ministerial level project, host), national postdoctoral workstation scientific research project-Key technology research of advanced analysis theory and application of steel structure (host), National Natural Science Foundation project (537878)-Advanced analysis theory of three-dimensional steel structure (cooperative research and main research) Concluded), Science and Technology Plan Project of Ministry of Housing and Urban-Rural Development (21-K3-33)- Research on Seismic Performance of New Structure of Semi-rigid Steel Frame-Steel Reinforced Concrete Shear Wall (Moderator), Science and Technology Plan Project of Guangdong Province-Research and Development of New Technology for Isolation of Rural Houses (Concluded), Science and Technology Plan Project of Ministry of Housing and Urban-Rural Development (28-K2-36)-Research on semi-rigid connection intelligent model and its application in second-order analysis of steel structure (moderator), Science and Technology Plan Project of Ministry of Construction (26-K3-2)-Research on key technologies of long-span irregular space steel reticulated shell structure (moderator), Key scientific and technological project of Ministry of Construction (24-165)-Research on optimal design method of steel frame structure based on genetic algorithm and structural ultimate bearing capacity (moderator), research and development project of Ministry of Construction (28-K2-36)-Research on semi-rigid connection model and its application in second-order analysis of steel structure (moderator), Key scientific and technological project of Gansu Science and Technology Commission (CK-953-2-135A) At present, the Ministry of Housing and Urban-Rural Development's science and technology plan projects and related horizontal scientific research projects, as well as professional master's training, which are also cooperating with Guangdong Architectural Design and Research Institute, Guangzhou Design Institute, Southeast Grid Corporation, Urban Construction General Company and Guangzhou Wuyang Steel Structure Company, have also achieved some phased results. A book "Steel Structure Design and Engineering Application" has been published in Science Press (the first edition), and the monograph "Simplified Analysis Principle and Application of Steel and Concrete Mixed Structure" is to be published (November 213, More than 5 academic and teaching research papers have been published in core journals, journals above the provincial level and international conferences at home and abroad, and some of them have been included by EI and ISTP. In August 211, a monograph "Second-order Inelastic Analysis Theory and Calculation Application of Steel Structures" was published in Science Press. In recent years, some innovative research achievements have been made in the calculation and design methods of steel-concrete mixed (combined) structures, advanced analysis theory of steel structures, nonlinear calculation theory and application of steel structures, calculation theory of new complex long-span spatial steel structures, design methods of tunnel-building connected structures and seismic performance research. Won the second prize of provincial scientific and technological progress; 1 first prize of scientific and technological progress at the municipal and departmental levels. Now he is a reviewer of several international academic journals, as well as domestic first-class authoritative academic journals such as the Journal of Civil Engineering. At present, I also participated in the compilation of Technical Specification for Steel Structure Design in Guangdong Province (212-213).
