To further elaborate on this point, in a frame structure composed of columns and beams, it is an absolute condition that columns and beams are rigidly joined to resist horizontal forces of 1 Q 1 and 2 Q 2 during an earthquake. When the column-beam intersection is rigidly joined, the bending stress due to the seismic load generated in the frame is large at both ends of the column and beam, as shown in Fig. 6.
The central part becomes smaller.

In a heterogeneous structure in which the columns are made of reinforced concrete and the beams are made of steel, the stress of the columns is not transmitted to the beams unless any measures are taken. However, it is easy to transfer the stress of a reinforced concrete column to a steel reinforced concrete beam, even if it is judged from the structural materials of the column and beam, and the stress of the steel reinforced concrete member is gradually transferred to the steel structural member. It is also easy, and this has been clarified both analytically and experimentally.
