      whole rotation

    In this paper, a general approach to establish differentia 1 equations of the forced vibration for the planar and spatial nonorthogonal bar-chain system under multi-support excitations,which may be arbitrarily irregular at each support and along each direction(x,y, z), is studied, considering the complicated geometrical constraint lelationship of the system,The final result of the study is given in form of forced vibration under the action of multiple equivalent disturbances.In the typical equations, the independent axis rotational displacements of the bar or chain are taken as the generalized coordinate vectors, of which the number of orders is evidently equal to that of degrees of kinematic indeterminacy of the system. The corresponding generalized mass matrix depends on both the mass distribution and the geometrical constraint characteristics of the system. The corresponding generalized stiffness matrix depends on both the stiffness characteristics and the geometrical constraint characteristics of the system.The equivalent disturbance matrix (i. e. the earthquake input) is the resultant of two components. One is inertial input which depends on accelerations on the multiple supports along differnt directions (x, y, z) and the mass distribution of the system. The other is elastic input which depends on the displacements on multiple supports along different directions(x, y, z)and the stiffness characteristics of the system. Furthermore, both components depend on the geometr cal constraint characteristics.The existing 3-dimensional theory of seismic loads and the expression of pseudostatic transmission of the earthquake are special cases for the results given in this paper.

    本文考虑非正交平面和空间杆链体系的复杂几何约束特性,着重研究地震在多个支点处沿各个方向(x,y,z)以各不相同的任意规律输入时,建立体系的地震强迫振动微分方程的一般性途径。 最终研究结果以等效扰力多点激发的强迫振动的形式给出。 典则方程中,广义坐标向量取为杆或链的独立的(整体)转动位移,其阶数显然等于体系的运动不定度。相应的广义质量矩阵既决定于体系的质量分布,又决定于几何约束特性。相应的广义刚度矩阵既决定于体系的刚度特性,又决定于几何约束特性。 等效扰力向量(即地震输入)为两部分合成,一部分为惯性输入,决定于多点沿名方向的地面运动加速度和体系的质量分布,另一部分为弹性输入,决定于多点沿各方向的地面运动位移和体系的刚度特性,而且二者都还决定于几何约束特性。 现有三维地震力理论公式和地震伪静力传输表示式是本文结果的两种特殊情形。

    A rigid pier foundation is sufficiently stiff to displace (rotate) under lateral load without causing appreciable distortion from its axis, The lateral displacement at any depth is related to the center of rotation without exception.This condition simplifies the displacement compatibility analysis and has generated a proliferation of "rigid pier" solutions. The lateral load-deflection response of a rigid pier sometimes maybe significantly influenced by the friction force at the interface between the pier and soil; this fact, however, is not often considered in most of the published rigid pier solutions. In this paper a better answer is given for the problem, taking into account the effect of the lateralfriction force by the subgrade-reaction approach, in which the pier reaction at any point is described to be directly proportional to the deflection and a power function with the depth at that point.

    横向力作用下的刚性基础,因具有足够的刚度而产生整体转动,其轴线的挠曲可略去不计。任一深度处的侧向位移均与转动中心有关。这一条件使刚性基础相应的位移分析得以简化,并提出许多“刚性基础”的解。基础与岩土接触面间的摩阻力对刚性基础侧向受挠的特性有时会产生显著的影响,而在许多“刚性基础”解中未予考虑。本文采用地基—反力理论,给出了考虑侧向摩阻力时的解,其中任一点的反力与该点的挠度及深度的幂函数成正比。

    Many single-story mill buildings were destroyed in Tangshan,Hai-cheng and Xingtai Earthquakes. In these buildings the damage of corner columns and columns remote from the terminal transverse wall are more serious than others. It means that the roof slabs were deformed and rotated in horizontal plane during earthquakes. According to the experimental data and conclusions drawn from the earthquake damage surveys, a spatial structural mechanical model in consideration of lateral stiffness of transverse masonry wall and its spatial action and rotational effect of roof slab has been established in the paper. The calculating scheme with "series-parallel multiple mass particles system" is adopted in the translation-torque coupling earthquake response analysis for single-story unsymmetrical mill buildings. A practical method according to the earthquake response spectrum is also given. Based on the calculation results of spatial analysis of several hundreds mill buildings, some applicable tables are made and a simplified method for manual calculation is presented in the paper as well.
