[摘要] 結(jié)合一個(gè)單層、較大跨度、較高層高、采用柱下鋼筋混凝土獨(dú)立基礎(chǔ)的單跨鋼筋混凝土框架結(jié)構(gòu)的工程設(shè)計(jì)實(shí)例，分別按框架柱腳固接和鉸接兩種計(jì)算模型，采用SATWE和JCCAD計(jì)算軟件對上部結(jié)構(gòu)和獨(dú)立基礎(chǔ)進(jìn)行計(jì)算，對兩種計(jì)算模型的計(jì)算結(jié)果進(jìn)行了對比分析。計(jì)算分析表明，對于此類結(jié)構(gòu)，按框架柱腳鉸接進(jìn)行設(shè)計(jì)比較合理，可減小基礎(chǔ)尺寸，達(dá)到在結(jié)構(gòu)安全、受力合理的前提下節(jié)約基礎(chǔ)工程造價(jià)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
