COLUMN SHORT STRUT STRUCTURE USING RECTANGULAR STEEL TUBE AND METHOD FOR DETERMINING CROSS SECTION OF COLUMN SHORT STRUT
PROBLEM TO BE SOLVED: To provide a reliable and economical column short strut structure and a method for determining a cross section of a column short strut by determining the cross section of a rectangular steel tube on the basis of deformation that is closer to reality when an assumed load acts.SOLUTION: In a column short strut structure using a rectangular steel tube installed as a support for both ends and subjected to a vertical load and an axial compressive load, the cross section of the rectangular steel tube is determined so as to satisfy the following formula with respect to the vertical load and the axial compressive load. N/N+M/M<1/φ, where N is the axial compressive force, Nis the yielding axial force, M is the bending moment caused by the vertical load and axial force action, Mis the yielding bending moment, φis the safety factor, and 1.2≤φ≤1.6.SELECTED DRAWING: Figure 1
【課題】想定される荷重が作用したときのより現実に近い変形に基づいて角形鋼管の断面を決定することにより、信頼性が高く、経済的なコラム切梁構造およびコラム切梁の断面決定方法を提供する。【解決手段】両端ピン支持として設置され、かつ鉛直荷重と軸圧縮荷重を受ける角形鋼管を用いたコラム切梁構造において、前記鉛直荷重と軸圧縮荷重に対して下記式を満足するように前記角形鋼管の断面を決定する。ただし、Ｎは軸圧縮力、Ｎyは降伏軸力、Ｍは鉛直荷重と軸力作用に伴い生じる曲げモーメント、Ｍyは降伏曲げモーメント、φcは安全率であり、1.2≦φc≦1.6の範囲とする。Ｎ／Ｎｙ＋Ｍ／Ｍｙ＜１／φｃ【選択図】図１
