BEAM WITH NONUNIFORM CROSS-SECTION
PROBLEM TO BE SOLVED: To enhance the yield strength against lateral buckling of a beam with nonuniform cross-section.SOLUTION: A beam with nonuniform cross-section comprises the following: a steel central beam part having a lower flange, a web and an upper flange; a steel beam end part having a lower flange, a web and an upper flange and connected with the central beam part, having a beam height larger than that of the central beam part, with the upper flange being connected to the upper flange of the beam central part or the lower flange being connected to the lower flange of the central beam part; a reinforcing plate connected to the lower flange or the upper flange of the central beam part and joined with the web of the beam end part; and a lateral buckling suppression part that is installed on the web of the beam end part around the reinforcing plate and suppresses lateral buckling that occurs at least on either of the central beam part or the beam end part.
【課題】変断面梁の横座屈耐力を向上させる。【解決手段】下フランジ、ウェブ及び上フランジを備えた鋼製の梁中央部と、下フランジ、ウェブ及び上フランジを備えて前記梁中央部と繋がり、前記梁中央部よりも梁成が大きく、前記梁中央部の上フランジと上フランジ、又は前記梁中央部の下フランジと下フランジが接続されている鋼製の梁端部と、前記梁中央部の下フランジ又は上フランジと繋がり、前記梁端部のウェブに接合された補強プレートと、前記補強プレート周囲の前記梁端部のウェブに設けられ、前記梁中央部及び前記梁端部の少なくとも一方に生じる横座屈を抑制する横座屈抑制部と、を有する変断面梁。【選択図】図１
