摘要
上部结构与地基基础共同作用事实上是存在的。本文采用“多肢并联墙”的力学模型,考虑上部结构与基础共同工作。但在框架结构中,由于梁柱截面均甚小,各节间均有局部的较大弯曲变形,所以参照V.N.Baikov的方法,考虑其影响、地基对上部结构与基础的共同作用计算则仍采用链杆法,文中举有例题,并对计算结果作了分析。
The interaction problem between soil foundation and upper frame structure in tall buildings is here introduced. If the subgrade reaction to the box-foundation under vertical load is known, the internal forces in box-foundation and upper frame structure is similar to the multipier shear wall under horizontal forces Hence, under vertical load, the soil and super structure interaction may be considered as a multi-pier shear wall lied on compressible foundation and is analyzed by use of link method which was suggested by Russian professor. Some examples for box and raft foundations are calculated and discussions about design problems for foundations of tall buildings are illustrated in this paper.
