【摘要】 不等高接地的坡地建筑结构是山地建筑中常用的一种结构形式,边坡变形导致不等高接地位置的基础变形不同,基础变形差的存在将在结构中产生内力。建立边坡作用下不等高接地坡地建筑结构的简化分析模型;分析边坡变形下简化模型的内力及梁跨、柱高变化下内力的变化规律;设计结构算例,分析算例结构的内力分布特征。研究表明:即使边坡发生微小变形时,在坡地建筑结构中亦会产生较大的内力;边坡变形引起的结构内力主要位于上接地第二层及以下各层,其中上接地第一层接地位置的梁和柱内力最大;可从设计方法和构造措施两方面改善边坡变形对结构的影响。结论可用于指导边坡变形下坡地建筑结构的设计,为后续的研究提供基础。更多还原

【Abstract】 The structure on the slope with uneven height grounding column ends is one of the most familiar structure types.Slope deformation results in different foundation deformation where it grounds in uneven height.The difference of foundation deformation leads to the existence internal force in structure.Simplified analysis model of building structure on the slope with uneven height grounding column ends is built up in this paper.Internal force of simplified model in the case of slope deformation is analyzed,as well as the change rule of internal force when beam span and column height vary.Structure example is designed and internal force distribution characteristic of the example is analyzed.The research shows that even if small slope deformation occurs,it will result in large internal force in building structure on the slope.Structure internal force caused by slope deformation mainly locates in the second floor above uneven height grounding and the floors below that.And the internal force of beams and columns in the first floor above uneven height grounding is the largest.The influence of slope deformation on structure can be improved via the design method and construction measures.Conclusions can be used to guide the design of building structure on the slope in the case of slope deformation,and to provide foundation for subsequent research.更多还原
