Main work

As an academic leader in the field of wood mechanics and wood structure engineering, Prof. Ren Haiqing has successively led more than 30 research projects, including the National Science and Technology Support Program for the 10th, 11th, and 12th Five Year Plans, the National Key R&D Program for the 13th and 14th Five Year Plans, the Forestry Public Welfare Industry Research Special Project, as well as the State Forestry Administration's 948 Project and the National Natural Science Foundation General Project. Significant progress has been made in the early prediction of wood mechanical properties, manufacturing and evaluation techniques for domestic wood (bamboo) structural materials, and evaluation techniques for the comfort and durability performance of wood structures. She has won one first prize and one second prize of Liangxi Forestry Science and Technology Progress Award, as well as one second prize of Beijing Science and Technology Award. She also ranked third and won one major scientific and technological achievement award from the Chinese Academy of Forestry. She has authorized 18 national invention patents and 10 utility model patents. She has obtained 5 provincial and ministerial level or above certification achievements and published over 100 academic papers in core journals both domestically and internationally, including 22 papers indexed by SCI and 35 papers indexed by EI. She has authored one book and contributed to three others, and have led the development of 6 national standards.

Prof. Ren Haiqing has innovated in the unified reliability design theory of structural wood materials, developed high-quality manufacturing technologies for structural wood materials, established a high-precision evaluation technology system for the load-bearing performance of structural wood components, and set up more than 10 demonstration production lines for structural Glulam and reconstituted bamboo, which have laid the theoretical foundation and provided technical support for the application of domestic plantation timber in building structures.
