【摘要】：聯(lián)肢剪力墻彈性階段的內(nèi)力分布、抗側(cè)剛度等工作性能主要受墻肢與連梁剛度的影響。為了準(zhǔn)確分析外包鋼板-混凝土聯(lián)肢組合剪力墻的受力性能,對外包鋼板-混凝土組合連梁的剛度進(jìn)行了分析�；阡摪迮c混凝土無相對變形和忽略混凝土抗拉強度的基本假定,建立了組合連梁鋼與混凝土無滑移的截面內(nèi)力與變形之間的關(guān)系,并推導(dǎo)了截面剛度的計算公式。對于常用工程設(shè)計參數(shù)范圍內(nèi)的組合連梁,考慮滑移后得到的抗側(cè)剛度相比無滑移情況減小了10%~24%。通過對無滑移組合連梁剛度公式中的混凝土部分貢獻(xiàn)的折減(折減系數(shù)為0.5),得到了無特殊界面構(gòu)造的外包鋼板-混凝土組合連梁的剛度計算公式。通過與有限元分析和試驗結(jié)果的對比,驗證了公式的準(zhǔn)確性。
[Abstract]:The internal force distribution and lateral stiffness of coupled shear wall are mainly affected by the stiffness of wall and connecting beam. In order to accurately analyze the mechanical behavior of sheet-concrete composite shear wall, The stiffness of sheet-concrete composite beam is analyzed. Based on the assumption that there is no relative deformation between steel plate and concrete and the tensile strength of concrete is neglected, The relationship between internal force and deformation of steel and concrete sections without slip is established, and the calculation formula of section stiffness is derived. The lateral stiffness after considering slippage is reduced by 10% and 24% compared with that without slip. By reducing the contribution of concrete part in the stiffness formula of non-slip composite connecting beam (the reduction coefficient is 0.5), the outer clad steel without special interface structure is obtained. Stiffness calculation formula of slab-concrete composite beam. Compared with finite element analysis and test results, The accuracy of the formula is verified.
