“箱形梁的受力分析”是交通部的科研项目,已由福州大学土建系结构工程研究所郭金琼教授为主的课题组完成,并于1989年2月28日通过了由交通部公路规划设计院主持的科研成果鉴定。科研小组的研究人员应用变分法,有限无(条)法、影响线等方法系统地分析了箱形梁弯曲的剪力滞后效应,扭转的畸畸变问题、横向内力以及复杂的变截面箱形梁的畸变与横向内力分析,提出了实用的计算方法,在研究过程中还进行了大量的 “Box Beam Force Analysis” is a research project of the Ministry of Communications, Fuzhou University Department of Civil Engineering Structural Engineering Institute Professor Guo Jinqiong based Task Force completed and on February 28, 1989 adopted by the Ministry of Transportation Highway Planning Design Institute presided over the scientific research appraisal. Researchers in the research group systematically analyzed the shear lag effect, the distortion of torsion, the transverse internal forces, and the complicated box with variable section by using the method of variational method, finite element method and influence line. Beam distortion and lateral internal force analysis, put forward a practical method of calculation, in the course of the study also carried out a large number of
