The formulae for both the vertical displacement ofthe points outside and inside of the base of a rectangular foundation and theaverage displacement of the foundation are presented. The results obtainedfrom the relevant formulae are shown by charts and numerical tables, and com-pared with those from the other existing methods to verify the validity ofthe method presented in this paper. Finally, the determination of the parame-ters related to the lumped mass-spring-dashpot analog for rectangular founda-tion vibration is also discussed in brief.

In this paper, the structures of five topologies on product spaces are discussed. A structural representation of the inductive limit topology is given by means of the Hamel base of a linear space, and another structural representation of the induced topology is given as Well. Then the relationships between the five topologies are discussed. Among these topologies the one- ordering topology is put forward by the author himself. In accordance with the mutual relationships between the five topologies on pro duct spaces, some properties concerning these topologies are discussed in this pader. The author also introduces the concept of maximal compatible subspace with respect to a topology on a linear space, which becomes a topological linear spaece, and the maximal compatible subsbaces are given to the box topology, the one-ordering topology and the induced topology on propuct spaces respectively, The completeness of the maximal compatible subspace with respect to the three topologies on the product space is given in a unified form. In this paper, the relationships between the normed topology, the projective limit topology, and the inductive limit topology on the Limit spaces, and also the relationships of the relative topologies of these topologies on the subspaces of the limit spaces are discusseo with theaid of structure. On the other hand, by taking advantage of the discussion on the completeness of the maximal compatible subspace with respect to the one-ordering topology, the proof of the sufficiency of the condition in the main proposition (4.1) cf [8] is much simplified.

本文讨论了乘积空间上五种拓扑的结构,利用线性空间的Hamel基给出了归纳极限拓扑的一种构造表示,给出了归纳拓扑的另一种构造表示,比较了这五种拓扑的相互关系。其中的共序拓扑是作者提出来的。在本文中利用乘积空间上五种拓扑的相互关系讨论了一些有关的性质。作者提出了线性空间上拓扑的极大相容子空间的概念,分别给出了乘积空间上盒拓扑共序拓扑和归纳拓扑的极大相容子空间,并且统一给出了关于乘积空间上这三种拓扑极大相容子空间完备性的命题。本文还从结构上比较了极限空间上范数拓扑与相关的射影极限拓扑,归纳极限拓扑之间的关系,以及极限空间的子空间上这几种拓扑的诱导拓扑的关系。另外,利用对共序拓扑的极大相容子空间完备性的讨论,对[8]中主要命题(4.1)条件充分性的证明给予了简化。

When the base of a structure is quite large, some finite time is necessary for the seismic wave traveling from one side to the another. Therefore, a considerable error may arise if one still take the foundation rock as a rigid base. Dibaj and Penzien had dealt with this problem, considering the reponse displacement of structures to the traveling waves as the sum of the dynamic displacement due to the rigid body motion of base rock and the so-called quasi-static displacement induced by its deformation....

When the base of a structure is quite large, some finite time is necessary for the seismic wave traveling from one side to the another. Therefore, a considerable error may arise if one still take the foundation rock as a rigid base. Dibaj and Penzien had dealt with this problem, considering the reponse displacement of structures to the traveling waves as the sum of the dynamic displacement due to the rigid body motion of base rock and the so-called quasi-static displacement induced by its deformation. In this paper the authors propose a similar method and use it in the nonlinear earthquake response analysis of earth structures.

如果建筑物的底宽相当大,地震波从一端传至另一端需要一定时间,这时就不能把基岩当作刚性体看待。对于这个问题,国外已有的分析方法是把建筑物的位移看作由刚性基底上的动力位移及基底弹性变形引起的准静力位移两部分叠加而成。本文发展了这一方法,把它用于土工建筑物非线性动力分析,得出一些初步结果。
