[摘要]為研究懸掛墻板減震框架結(jié)構(gòu)的動力性能,將懸掛墻板視為剛性吊桿,將其簡化為框架懸掛結(jié)構(gòu),建立自由振動基本方程,明確了主體框架結(jié)構(gòu)與吊桿振型分量之間的關(guān)系,給出了懸掛墻板減震框架結(jié)構(gòu)頻率的理論計算公式,并與振動臺試驗結(jié)果進行對比。進一步將其與傳統(tǒng)砌體填充墻框架結(jié)構(gòu)的動力性能進行對比,明確了懸掛墻板減震框架結(jié)構(gòu)的減震效果,并針對其影響因素進行討論,給出了這種結(jié)構(gòu)的基本設計原則。

Abstract:In order to study the dynamic performance of suspended wallboard frame structure, suspended wallboard was regarded as rigid hanger rod, which was simplified as frame suspended structure. The basic equation of free vibration was established. The relationship between the mode component of main frame structure and the mode component of hanger rod was clarified. The theoretical calculation formula of suspended wallboard energy-dissipated frame structure frequency was given and compared with the shaking table test results. In addition, the dynamic performance of the frame structure with traditional infilled walls was compared, and the effect of suspended wallboard on the energy dissipation of the frame structure was clarified. The related influencing factors were discussed, and the basic design principles of the structure were given.
Keywords:frame structure; suspended wallboard; dynamics characteristic; energy dissipation; hanger rod
