A study is carried out about the imperfection for design methods of the wall-beams in the Code GBJ3 - 88, and the suggestions of improvement and supplement are presented. The distribution of stresses and inner forces of the simply-supported wall-beams by the finite element analyses is groped for. The approximate calculation for inner forces of the bressummer and the simplification of calculation for bearing capacity of the beams are presented and the calculation of the walls in the wall-beams is bettered. The calculated example and the comparison between the method and other methods are given.
