【発明の詳細な説明】 〔産業上の利用分野〕 この発明は、箱形断面形をなす鉄骨柱とＨ形断面形を
なす鉄骨梁との接合部のパネルゾーンを補強した柱・梁
接合部構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a column / beam joint in which a panel zone of a joint between a steel column having a box-shaped cross section and a steel beam having an H-shaped cross section is reinforced. Regarding the structure.
一般に、箱形断面形の鉄骨柱にＨ形断面形の鉄骨梁を
接合する場合、鉄骨梁を鉄骨柱の側面部に単に接合した
だけでは、鉄骨梁のウェブが接合される柱フランジの面
外曲げ剛性がウェブの曲げ剛性に対して相対的に小さい
ため、ウェブの強度が梁の全成にわたって有効とならず
充分な強度が得られない。In general, when a steel beam having an H-shaped cross section is joined to a steel column having a box-shaped cross section, simply joining the steel beam to the side portion of the steel column is out of the plane of the column flange to which the web of the steel beam is joined. Since the bending stiffness is relatively small with respect to the bending stiffness of the web, the strength of the web is not effective over the entire beam, and sufficient strength cannot be obtained.

We developed a method to address the problem and filed an application (see Japanese Patent Application No. 1-123433).

減化が図れるなどの効果がある。The steel column is formed into a box-shaped cross section by welding a plurality of side plates, and the vertical stiffener and the horizontal stiffener are separated from each other, separated from the upper and lower diaphragms, and further welded only to the side plates. Since it is attached (see, for example, FIG. 1), when a plurality of side plates are welded to form a steel column having a box-shaped cross section, the vertical stiffener and the horizontal stiffener concealed in the steel column are each attached. Pre-installed on the inside of the side plate makes it easier to install vertical and horizontal stiffeners, which makes it easier to process and manufacture the beam joints of steel columns and to simplify the preparation of steel columns In addition, there is an effect that the manufacturing period can be shortened and the manufacturing cost can be significantly reduced.
