In this paper, the formula to evaluate the required tensile capacities of connections at column's top and bottom for conventional post and beam structural system having sheathed walls with openings, which are extended assuming rigidity of beams and floors in three dimensional structures from one previously derived assuming rigidity of beams in plane structures by authors, is presented and experimentally verified.The formula to evaluate normal force of column consists of the sums of the dead normal force, the normal force caused from the over turning moment by the horizontal shear force acting on upper stories, and vertical shear force produced in the shear wall carrying the shear resistance. The formula has been verified by carrying experiments on a two story three dimension structure with 26 kind variables. Dividing three dimension effect into perpendicularly arranged columns and walls effect to loading direction, the generating mechanisms have been experimentally made clear. For the variable of the bending stiffness of beam, experiments clearly shown that the beam deformation could not been disregarded.
