1. Under the assumption of plane section, the 3D displacement field equation is discretized in terms of nodal displacements.

2. For NC machining of plane section method, the machining path of tool cutting plane and implicit surface can be found, and the curve of the tool path is drawn by the positive-negative method.

3. A plane section of a surface of revolution containing the axis of revolution.

3. try its best to collect and create good sentences.

4. Based on plane section computational assumption, the constraint equations of element nodes' degree are used and the simplified finite element method is proposed.

5. With theoretical method based on the assumption of plane section, the influence of steel reinforcement ratio, CFRP amount and initial loading level on the flexural strength is analyzed.

6. Following the process of construction, considering the worst loads, according to the assumption of plane section, the steel girder alone and the composite girder are computed respectively.

7. The computation of stress resulted by external load is relatively complex because the deformation of unbonded prestressed strand cannot comply with the plane section assumption.

8. The strain measurement proves that the average strains agree with the assumption of plane section.

9. During the beam of recycled aggregate concrete being under the load, the changes of the normal section's stain were complied with the assumption of plane section.

10. As to bonded concrete beams, complete bond between steel and concrete is always assumed, so analysis can be performed based on plane section hypothesis.
