Author calculated the response analysis on the vibration of the steel space structure due to the strong earthquake motions by using the electric digital computer, and discussed the influence of the displacements and the stresses due to horizontal and vertical ground motions and the distribution of the seismic coefficient. This paper is the third report of the series on the dynamic response analysis of the space structure for the earthquakes. These results are as follows : (a) It is shown that the maximum displacement due to vertical ground motions get near the maximum displacement by horizontal and vertical ground motions in the steel space structure. (b) It is shown that the maximum stresses in the streel space structure is different due to the relation of the strong earthquake motion and the first natural period. (c) It is shown that the distribution of the seismic coefficient in the steel space structure is similar to the mode shape of the first natural period.
