摘要
运用空间Timoshenko梁理论对构架式基础进行了动力分析,全面考虑了轩件的转动惯量、剪切变形和刚性域等因素;同时,应用弹性半空间理论,研究了地基变形对基础动力反应的影响。通过算例显示了上述各种因素的作用。
Basing on the theory of space Timoshenko beam, the authors of this paper study the dynamic analysis of frame—type foundations with respcet to rotatory inertia, shear deformation and nodal rigid regions. Besides, using the elastic half space model, they investigate the effect of deformation of soil stratum on the dynamic responses and give examples to illustrate functions of the aforesaid factors.
