梁のハンチの応力分布に関する研究

抄録

In this paper, the reporters shall discuss the results from comparing the stress distributions in haunches of beams, when horizontal and vertical forces are added, obtained from applying the solution of the theory of two-dimensional elastity, with photoelastic experiments. The theoritical values of the solution quite agree with the experimental values at the middle part of the haunch (Fig. -7 II, 11 II) and at part I of the haunch which is nearer to the center of beam (Fig. -7 I, 11 I). At the upper and lower part of the the haunch nearer to the beam-column connection (Fig. -7 III, 11 III), the stress distributions by superposition of the stress of the solution of the theory of two-dimensional elastity upon the stress distributions of infinitely large plate under a concentrated load, are similar to that of experimental results. Therefore this solution of theory of two-dimensional elasticity is quite effective when applied to the middle and part I, farthest from the beam-column connection, of the haunch. As to the part of the haunch nearest to the beam-column connection, it would be possible to consider that stress distributions at that part are sum of the solution above and the stress distributions due to the restriction of the column.
