［摘要］以桁架-拱為基本模型，分析了彎矩、剪力及軸力對構件受剪極限承載力的影響。在滿足下限定理的條件下，建立了反復荷載作用下型鋼混凝土構件受剪粘結破壞模型，并給出相應的受剪承載力計算公式。最后用相關文獻中的試驗數(shù)據(jù)對模型和計算公式進行了驗證。結果表明，計算模型和公式與試驗吻合較好且偏于安全。

Abstract:Taking the truss-arch as the basic model, the effects of bending moment, shear force and axial force on the ultimate bearing capacity of the members were analyzed. Under the condition of satisfying the lower limit theorem, a shear bond failure model of steel reinforced concrete members under cyclic loading was established, and the corresponding formula for calculating the shear capacity was given. Finally, the model and calculation formulas were verified with experimental data in related literatures. The results show that the calculation models and formulas are in good agreement with the tests and are more secure.
Keywords:seismic performance; shear capacity; truss model; composite structure; steel reinforced concrete; lower limit theorem
