【Abstract】 Some items in technical codes GBJ10—89, GBJ11—89 and JGJ3—91 are discussed for a type of frame structure with attached shear bending bars. It is pointed out that existing method of shear resistence calculation in technical codes is not suitable for the joints on beams, and a new calculation method and formulas are put forward. Compared with the present unreasonable principle of stronger column and weaker beam for the bending of the joints on beams, the principle of stronger beam and weaker column is necessary.更多还原
