【提要】  推導(dǎo)了在水平荷載作用下共同工作的兩個(gè)彎剪型抗側(cè)力結(jié)構(gòu)的基本微分方程組及其解析解。與傳統(tǒng)框架剪力墻結(jié)構(gòu)可以一次求解不同，兩個(gè)彎剪型結(jié)構(gòu)共同作用的分析必須分兩步求解。算例分析表明，一個(gè)結(jié)構(gòu)的抗彎剛度參與另一個(gè)結(jié)構(gòu)共同工作的能力受到自身抗剪剛度的影響，一個(gè)結(jié)構(gòu)的抗剪剛度參與另一個(gè)結(jié)構(gòu)共同作用的能力也受到自身抗彎剛度的影響。

Interaction Between Two Shearflexural Structures Under Horizontal Load/Gao Yu，Tong Genshu （Department of Civil Engineering，Zhejiang University，Hangzhou 310027，China）
Abstract:The equations and its analytic solution are discussed，considering the interaction between two shearflexural structures under horizontal load. Different from the simplified model for framewall system，the equations need two steps to solve. The examples show that the efficiency of the flexural rigidity in one structure to participate in resisting load together with the other structure in a dual system is affected by its shear tiffness.Meanwhile，the efficiency of the shear stiffness in one structure to participate in resisting load is affected by its flexural rigidity.
Keywords:dual system；frame；shear wall；shearflexural type
