摘　　要：为揭示框架结构楼层侧向刚度与砌体墙稳定性分别与哪些尺寸参数函数表达式线性相关,明确研究对象与尺寸参数几次幂函数正相关还是负相关,本文针对框架结构通过推导规范给出的侧向刚度公式,得出线性相关的尺寸参数函数表达式;针对砌体墙稳定性,以稳定性水准一致为原则,通过压杆稳定性分析推导出与墙体稳定性线性相关的尺寸参数函数表达式。结论可解决两类问题:首层层高大、上部标准层层高正常的框架结构为避免侧向刚度不规则,定性确定框架柱截面尺寸;以研究充分的200 mm厚顶部铰接自承重墙成果为基准,用比值法直接推导出稳定性水准一致的不同墙厚顶部铰接自承重墙高度及顶部自由自承重墙高度。本文结论可为相关工程设计提供参考。In order to reveal which dimensional parameter function expressions are linearly related to the lateral stiffness of the frame structure floor and the masonry wall stability,to know whether the research object is positively or negatively correlated with the dimensional parameters several times,in this paper,aiming at the lateral stiffness formula given by the derivation specification for the frame structure,a linearly related dimensional parameter function expression is given.Aiming at stability of the masonry wall,based at the principle of consistent stability level,the dimensional parameter function expression that is linearly related to the wall stability is derived through stability analysis of the pressure lever.The conclusion can solve two types of problems:the frame structure with high first floor and normal upper standard floor height is used to qualitatively determine the cross-section size of the frame column in order to avoid irregular lateral stiffness;based on the fully researched results of the 200 mm thick top hinged selfbearing wall,and the ratio method is used to directly derive the height of the hinged self-bearing wall at the top and the free self-bearing wall at the top with different wall thicknesses and same stability level.The resullts can provide references for similar projects.
