摘要： PROBLEM TO BE SOLVED: To provide a beam structure and a beam end widening method for fixing a horizontal rib plate to a flange with a small amount of welding.
SOLUTION: Double bevel groove machining is performed for a welding surface 10 of the horizontal rib plate 9 to a flange 7 with a non-welding part 27 left in the center thereof. The thickness of the non-welding part 27 is calculated as in the following. In the tip 13 of the horizontal rib, the state where the H-steel 5 reaches a bending strength M
u , that is, the state where the right stress intensity σ
2 of the flange 7 reaches tensile strength σ
u is
set to calculate the right stress intensity σ
1 at the beam end 11 according to a gradient 23 of moment diagram 21 of the beam 3. Supposing that the right stress strength P
1 of the horizontal rib plate 9 at the beam end 11 is transmitted by shear force between the horizontal rib plate 9 and the flange 7, the thickness of the non-welding part 27 is calculated so that the shearing stress strength τis below the final shearing strength τ
u . The beveled horizontal rib plate 9 is fixed to the flange 7 of the H-steel 5 by welding 15 to form the beam 3.

摘要： PURPOSE:To exhibit energy absorbing capacity possessed by lead by a method wherein a tensile force is prevented from being exerted on the lead and the lead is burdened with a shearing stress. CONSTITUTION:A lead damper comprises block-form lead 1, a tubular constraining tube 2 with which a peripheral surface 11 of the lead 1 is surrounded throughout the whole area thereof, and two mutually rotatable fixed plates 31 and 32 which nip the lead 1 from end faces 12 and 12 and are fixed to the respective end faces 12 and 12 and one of which is formed integrally with the constraining tube 2 and the other of which is insulated from the constraining tube 2. Since the volume change of the lead 1 is constrained from a triaxial direction by means of the constraining tube 2 and the two fixed plates 31 and 32, the lead damper is stable to the occurrence of a crack. The fixed members 31 and 32 are connected to relatively rotational displacing members during vibration of a structure, and through relative rotational deformation of the fixed plates 31 and 32, twist moment is exerted on the lead 1. Burdening with a shearing force causes absorption of vibration energy of the structure through energy absorption capacity thereof.
