| Research Abstract |
In this paper, the effect of partial loss of sectional area at the flange of H-beams due to bolt holes on the statical characteristics were experimentally investigated in three test series. The test results show that such effect is estimated by considering not only the loss of sectional area of flange plates but also the reduction of plastic section modulus. When the rate of reduction of sectional area is smaller than 25%, such reduction of sectional area has small influence upon the statical characteristics of the beam. And it becomes clear that maximum strength and plastic deformation capacity decrease with increasing the rate of partial loss of sectional area, and that the reduction of maximum strength and plastic deformation capacity can be compensated by using high strength bolted friction joints at the part of bolt holes.
