FLOOR VIBRATION PERFORMANCE ADJUSTMENT METHOD, FLOOR VIBRATION PERFORMANCE ADJUSTMENT PROGRAM, AND DOUBLE FLOOR STRUCTURE
To provide a technique capable of improving the applicability of a double floor structure construction.SOLUTION: A floor vibration performance adjustment method is a floor vibration performance adjustment method of adjusting floor vibration performance of a double floor structure including: a slab in a building; and a floor constituting part that includes a first member composed of a square steel pipe or H-shaped steel installed on the upper side of the slab, and a first support member supporting both ends of the first member from below. The method includes a natural frequency determination step for determining a natural frequency f. In the natural frequency determination step, when assuming that an axial length of the first member as L0, a boundary condition of the first member as λ, a bending stiffness of the first member as EI, and a weight per unit length of the first member as ρA, a support span L1 less than a length L0 of the first member is set based on a placement position of an adjustment member away from the edge of the first member, and the natural frequency f is determined.SELECTED DRAWING: Figure 7
【課題】二重床構造の施工の適用性を向上させることが可能となる技術を提供する。【解決手段】実施形態に係る床振動性能調整方法は、建物におけるスラブと、前記スラブの上側に設けられる角形鋼管又はＨ形鋼で構成される第１部材と前記第１部材の両端を下方から支持する第１支持部材とを有する床構成部と、を備えた二重床構造の床振動性能を調整する床振動性能調整方法であって、固有振動数ｆを決定する固有振動数決定工程を備え、前記固有振動数決定工程では、前記第１部材の材軸方向の長さＬ０とし、前記第１部材の境界条件λとし、前記第１部材の曲げ剛性ＥＩとし、前記第１部材の単位長さ当たり重量ρＡとしたとき、前記第１部材の端部から離間される調整部材の配置位置に基づいて、前記第１部材の長さＬ０未満の支持スパンＬ１を設定し、前記固有振動数ｆを決定する。【選択図】図７
