在钢管混凝土柱体系的梁柱组件设计中，采用了日本建筑学会(AIJ)建立的设计公式。然而，在现行的AIJ标准中，设计公式的范围仅限于普通材料的强度；即混凝土的无侧限抗压强度高达36兆帕斯卡，结构钢管的抗拉强度高达490兆帕斯卡。因此，本文研究了较高的材料强度对组件性能的影响。试验结果表明，上述AIJ设计公式适用于混凝土的无侧限抗压强度为110 Mpa，结构钢管的抗拉强度为809 Mpa。提出了组合体中剪力板恢复力特性的解析模型，并与试验结果进行了比较，结果表明该模型具有较高的精度。
In the design of beam-to-column subassemblies in concrete-filled steel tubular column systems, a design formula established by the Architectural Institute of Japan (AIJ) is applied. However, in the current AIJ standard, the scope of the design formula is limited to ordinary material strengths; i.e. up to an unconfined compression strength of 36 MPa for concrete and tensile strength of 490 MPa for structural steel tubes. So, the effect of higher material strengths on subassembly behavior is studied in this investigation. The experimental results presented in this paper verified that the above-mentioned AIJ design formula is applicable up to an unconfined compression strength of 110 MPa for concrete and tensile strength of 809 MPa for structural steel tubes. An analytical model for the restoring force characteristics of the shear panel in the subassemblies was also proposed, and was found to reproduce the experimental results with good accuracy.
