［摘要］討論了短肢剪力墻的實用判別依據(jù)。首先根據(jù)聯(lián)肢剪力墻的力學特征，導出了多肢剪力墻力學性能參數(shù)T，Ψ的實用計算公式，由此分析了參數(shù)T的物理意義；然后對墻肢長厚比在5～8之間，且整體參數(shù)α<10的剪力墻，進行了力學性能分析，表明參數(shù)T增大會減小墻肢彎矩、軸力與側移，但對墻肢剪力無影響；另外，參數(shù)T對墻肢剪跨比影響不大。由此建議短肢剪力墻的墻肢長厚比在5～8之間，且整體參數(shù)α<10，但參數(shù)T不需限制；最后給出了短肢剪力墻中連梁截面高度與其凈跨度比值的限制條件。
［關鍵詞］短肢剪力墻；連梁；高跨比；整體參數(shù)；實用判別

Abstract:The basis for practical judgment of short-pier shear wall has been discussed. Firstly, the practical calculating formulas of the mechanics parameter T and Ψ have been derived from the mechanics property of coupled shear wall, from which the physics meanings of parameter T have been researched, then the mechanics properties have been analyzed which the ratio of the length of wall pier to the wall thickness may be between 5 and 8, and the monolithic parameter α may be less than 10. The results indicate that the meaning of the parameter T may reduce the moment, the axial force of the wall pier and the lateral displacement of the wall, but the parameter T has no influence on the shearing force of the wall, and hardly exert an influence on the shear span ratio of the wall pier. From this, it may be proposed that the ratio of length of the wall pier to the wall thickness may be between 5 and 8, and the monolithic parameter α may be less than 10, but the parameter T should not be limited. Finally, the limited requirement of the ratio of the height of connecting beam to its net span in the short-pier shear wall has been given.
Keywords:short-pier shear wall； connecting beam； ratio of height to span； monolithic parameter； practical judgment
