摘要： PURPOSE:To reduce cost by forming a beam with the arrangement of a plurality of clustering members between upper and lower chord members at the predetermined intervals, and positioning an arch member between the support points of the beam. CONSTITUTION:An arch member 4 is continuously extended between right and left support points of a beam A, and the center portion thereof is made to project up or down roughly in the form of a parabola. Also, both ends of the arch member 4 is jointed to both ends of an upper chord member 1, and the intermediate section thereof is jointed to a clustering member 3 and a lower chord member 2. Furthermore, the joints of the arch member 4 and the upper chord member 1, and the lower chord member 2 and the clustering member 3 are respectively made rigid, thereby uniformly treating stress acting on a floor due to an eccentric load. Furthermore, slant plates 5 and 5 are arranged at both sides of the clustering member 3 approximately in a Y-form for improving vibration properties between arches.

摘要： PROBLEM TO BE SOLVED: To provide a method for evaluating sound insulation performance between adjacent chambers and a selected side wall capable of calculating and evaluating quantitatively the sound insulation performance of the side wall by calculating a side wall solid propagation sound between the adjacent chambers as a vibration acceleration level propagating inside the side wall. SOLUTION: When evaluating the sound insulation performance between adjacent chambers enclosed by the side wall 4 intersected with a door boundary wall 3, the sound pressure level of a propagated side wall solid propagation sound (a symbol of a trancated chevron shape) is calculated as a sound pressure level determined from the sound pressure of a sound source chamber 1 after entering the side wall 4 on the sound source chamber side, being propagated inside the side wall 4 with internal damping, and being radiated from the side wall 4 on the sound receiving chamber 2 side, and synthesized quantitatively with a direct transmission sound through the door boundary wall, to thereby calculate the sound pressure level in the sound receiving chamber. Hereby, the sound insulation performance between the adjacent chambers is calculated and evaluated quantitatively.

摘要： PROBLEM TO BE SOLVED: To prevent stress concentration and improve durability by inserting an elastic material bonded to a plate into a gap between a prism-shaped protrusion erected on a roadbed foundation and a notch in the joint of floating slabs and fixed to the protrusion. SOLUTION: A sleeper 4 is provided under a track 1 and floating slabs 2 which are charged with ballast 6 through a sleeper mat 5 are provided. The slabs 2 are mounted on a roadbed foundation 8 through vertical vibration preventing supports 7. A prism-shaped protrusion 9 is erected on the foundation 8 and if two floating slabs 2 are parallelly disposed in the direction of the track 1, a U-shaped notch formed in the joint of the slabs 2 is slipped onto the protrusion 9. And elastic materials 11 bonded to plates 12a, 12b are inserted into gaps between the protrusion 9 and the slabs 2b and fixed to the protrusion 9 and a spacer 13 is fixed to the notch of the slabs 2. As a result, forces can be dispersed in the direction of the track and normal to the direction thereof.
