[提要]  研究了短肢剪力墻宏觀的力學(xué)性能，主要包括：通過對(duì)判別式物理意義的研究，指出短肢剪力墻是一種強(qiáng)肢弱梁型的剪力墻；在理論研究、有限元分析和大量計(jì)算的基礎(chǔ)上，得出了水平荷載下短肢剪力墻的整體側(cè)移曲線屬于彎剪型的結(jié)論；同時(shí)給出了確定整體側(cè)移曲線反彎點(diǎn)位置的方程式和計(jì)算圖表。

The macroscopical mechanical performances of shear wall with short piers have been studied. Based on the study of the physic concept for the discriminant, it is pointed out that short pier shear wall is provided with strong piers and weak beams. Furthermore, by means of the theoretic researches, finite element analyses and a numerous number of calculations, it has been concluded that the lateral displacement curve of short pier shear walls subjected to the lateral forces belongs to the flexure-shearing type deformation. The equations and the diagrams to define the position of the contra flexural point in the lateral displacement curve are also provided.
Keywords:  short pier shear wall; lateral clisplacement curve; contra flexural point
