[摘要] 结合一个单层、较大跨度、较高层高、采用柱下钢筋混凝土独立基础的单跨钢筋混凝土框架结构的工程设计实例，分别按框架柱脚固接和铰接两种计算模型，采用SATWE和JCCAD计算软件对上部结构和独立基础进行计算，对两种计算模型的计算结果进行了对比分析。计算分析表明，对于此类结构，按框架柱脚铰接进行设计比较合理，可减小基础尺寸，达到在结构安全、受力合理的前提下节约基础工程造价的目的。

Abstract: Combined with a design example of single floor and large span reinforced concrete frame that reinforced concrete column independent foundation were used, the main structure and independent foundation were calculated separately by used SATWE and JCCAD software depend on column bottom fixed and hinge joint model. The calculation results of two model were compared. The analysis results show that, for this kind of structure, frame column hinged foot is more reasonable. That can reduce the independent foundation size to aclueve aim of the fundamental project cost saving under the structure safety and reasonable force.

Keywords: single-span frame; large span; column bottom lunge joint; column bottom moment
