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。
Combined with a single-span, large-span, high-rise, single-span reinforced concrete frame structure engineering design example using independent foundation of reinforced concrete under column, respectively, according to the frame column foot and articulated two kinds of calculation model, using SATWE and JCCAD The calculation software calculates the superstructure and the independent foundation, and compares the calculation results of the two calculation models. The calculation and analysis show that the design of this kind of structure is more reasonable by the hinge of the frame column foot, which can reduce the basic size and achieve the purpose of saving the basic project cost under the condition of structural safety and reasonable force.
