摘　　要：本文以一幢１０层两跨的钢筋混凝土框架结构房屋与土的协同工作为例．分析了条形基础下地基土发生的部分支承损失对结构构件内力的影响。结果表明，支承损失对构件内力有较大影响，但随着楼层的提高，其影响逐层衰减。An elastic interaction analysis has been conducted to study the effects of a local loss of support beneath the borm footing of a two-bay. ten-story reforced concrete plane frame structure. The results of the study indicate that the presence of a void will significantly affect the superstructure moments and foundation moments.With the stories increase. the influence lessens gradually.

关 键 词：钢筋混凝土 框架结构 地基土 支承损失 内力
