分割外ダイアフラム形式角形鋼管柱H形断面梁接合部の部分架構実験

摘要

This paper proposes design procedures that yielding of beams occurs before RHS-column to beam connections stiffened by rrnexterior diaphragms yield. Cyclic loading tests of beam-column subassemblages for interior columns were conducted in order to rrnverify the validity of the proposed design method, and elasto-plastic behaviors of beam-column subassemblages for exterior rrncolumn or concrete filled tube column were investigated. The test results reveal that the design method is valid. Stiffness rrnof beams with exterior diaphragms can be properly predicted by assuming that beams are connected rigidly to columns. rrnDeformation capacities of specimens whose beams are connected to exterior diaphragms with high-strength bolts are rrnsubstantially larger than that of the specimen that beam flanges and exterior diaphragms are welded.%本研究の目的は，外ダイアフラムを用いた角形鋼管柱梁接合部のrn設計法を確立することである．文献1）では，図1に示す直交梁の取rn付けも可能な任意形状の外ダイアフラムに対する設計式を提案するrnとともに，実験的にその妥当性を確認した．
