Analysis of beams prestressed with unbonded tendon is much more complicated than that of bondedconcrete beams.
无粘结预应力混凝土梁的分析要比有粘结混凝土梁复杂得多。

As to bondedconcrete 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。

P an external non-bonded tendon is a tendon situated outside the original concrete section and is connected to the structure by anchorages and deviators only.
