Internal Force Evaluation of Non-uniform Beam in Portal Frame Wenwen Jiaa, Dengfeng Wang b * School of Environment and Civil Engineering, Jiangnan University, Wuxi, 214122, China asmilejww@163.com, bhappywdf@126.com Keywords: portal frame, non-uniform beam, internal force evaluation, force method, numerical integration Abstract.
For engineering design, the evaluation of internal force is often based on the linear elastic theory, consequently, elastic material and linear small deformation is taken into account.
For engineering design, simplified accurate evaluation method of every controlling internal force item in portal frame being composed of non-uniform members is produced.
