| Abstract: | On basis of an engineering project,prestressed R. C. frame beam with haunches is introduced which can improve the flexural capacity and crack resistance by increasing the height of support section, this kind of beam's feature is analysed and the calculation method is given to treat the condition in which the bending regidity is variable and the section centroid is not in one line. |

| Keywords: | frame beam haunch prestress haunched area equivalent unbonded bar |
