This paper analyzes the relation between inclined cut and inclined connection of circular cone.

Comparative analysis on oblique section s bearing capacity calculation of members in bending;

The theoretical study on the shearing performances of the reversible member in bending oblique section;

Calculation method of strengthened RC beam oblique section with FRP based on the effective pasting length

The deficiencies about calculation method of ultimate loading capacity of normal section and diagonal section of slender beam in the current Concrete Structure Design Code (GBJ10\|89) are discussed in this paper.

diagonal section reinforcement is not usually conformed with the calculation by the Bridge Design Standard(JTJ023 - 85).

Traditional control method used for dual Buck inverter is ramp compare method with bias current which leads to poor efficiency.

Usually,the shear capacity of reinforced concrete beams under biaxial bending for concentrated load acts,was reduced to two beams for gaining each shear capacity of diagonal plane,then piled them up for the result of biaxial bending member.

In related pilot study, more cross-section of the reinforcement has been researched, but it has few study in strengthen diagonal plane section.

The reckoning approaches of the inclined cutting method and the least square method are derived for use in direct shear test s data processing.
