在相关的试验研究中，更多的是对正截面的加固研究，而对斜截面的抗剪加固试验研究还比较少。

The flexural strength calculated on the basis of the plane section assumption and strain compatibility condition agrees well with the test results.

根据平截面假定和应变协调条件计算的受弯承载力与实测值符合较好。

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

对于有粘结混凝土梁，一般认为钢筋和混凝土之间理想粘结，从而可基于平截面假定进行分析。

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

通过平截面计算假定，引入单元节点自由度的约束方程，提出了承载能力有限元计算的简化方法。

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.

无粘结筋的变形不符合平截面变形假定，因此由外荷载引起的应力计算比较复杂。
