上部结构的

In fact, the feedback from the inertia force of the upper structure will alter the movement of foundation and accordingly alter the dynamic behaviors of the upper structure.

然而，实际地震中，由于上部结构的反馈作用，使地基发生变形，引起基础相对于自由场地的平移与转动，从而改变上部结构的动力特性。

In this a paper, an effective method is presented to analyse the twodimensional frame on a layered foundation.

l引言在高层建筑和水工结构物的设计中，考虑多层地基和上部结构的相互作用是一个重要而复杂的问题。

The research results show that stiffness ratio of superstructure and ratio of damping and stiffness in isolated story have great influence on local deformation of structure. It can reduce the local deformation and increase entirety of structure effectively through rational laying rubber bearing and adjusting distribution of stiffness and damping in isolated story. The specific conclusion of the paper is that local deformation of isolated structure becomes minimality when translational stiffness ratio of superstructure is consistent with stiffness ratio of isolated story; and it also can reduce local deformation of minor structure by reducing damping ratio of isolated story properly.

本文研究表明，上部结构的刚度比及隔震层的刚度和阻尼比对结构的局部变形有着很大影响，通过橡胶垫的合理布置，调整隔震层的刚度和阻尼分布，能有效的减小结构的局部变形，提高结构的整体性，从而使隔震效果得以确保；本文的具体结论是，当上部结构的侧移刚度比与隔震垫刚度比一致或相近时，隔震结构的局部变形最小；适当减小子结构的隔震层阻尼比可减小该子结构的局部变形。

From the function needing of the building, the top needs small axis dimension which has to be assigned, the next function part hopes that there is as big as possible free space, it is heavy for network to take post, for satisfying building the requests of function, the structure must be by fixing up contrary to routine way, in order to realize that this kind fixes up, must set up a special floor between the underpart in structure forms are different, make it bear top the internal force of structure and transmit and give underpart structure to play structure change the floors of function reliable. It is called transfer floor.

从建筑功能的要求上讲，上部需要小开间的轴线布置，下部公用部分则希望有尽可能大的自由灵活空间，柱网要大，为了满足建筑功能的要求，结构必须以与常规方式相反进行布置，为了实现这种布置，就必须在结构形式不同的上下部之间设置一个特殊的楼层，使其能承受上部结构的各种内力，并将其可靠的传递给下部结构，这一能起结构转换作用的楼层，称为转换层。

The analysis on unilateral, bilateral and lateral-torsional coupled seismic response of base-isolated structures with lead rubber bearings is carried out. The maximal displacement of the bearings is studied. The influence on lateral-torsional coupled seismic response of base-isolated structures due to the excentricity and uncoupled period ratio of the superstructure, and the excentricity of the isolation system is investigated.

对铅芯叠层橡胶支座基础隔震结构进行了单向及双向地震反应对比分析，并研究了支座最大位移的确定；对结构进行了平—扭耦联地震反应分析，研究上部结构的偏心距及非耦联周期比、隔震层偏心距等因素对结构的平—扭耦联地震反应的影响，并对结构平—扭耦联地震反应的控制进行了探讨。

In the process of wave slamming, the impact pressures with short duration and high peaks occurs when the waves hit the subface of the structure, which causes the destabilization of superstructure and the fratigue failure of joints.

在波浪冲击过程中，当波峰刚接触到建筑物底面时会产生历时很短但强度极大的冲击压力，这种极强的冲击荷载会引起建筑物上部结构的失稳或造成结构连接处的疲劳破坏。

The question of ruined earth pressure cell in test is solved,and the contact pressure between soil and pile is found out by the numerical simulation and distributing law of earth pressure.

通过数值模拟，解决试验中土压力盒损坏的问题，得到地震动激励下桩–土接触压力峰值的数据，并由此分析桩–土接触压力的大小及其分布规律，提出桩基上的支盘是基础减振的主要构件，并承受动荷载，减轻地震波对上部结构的冲击力，同时消耗上部结构反馈给基础的振动能量。承台和桩基两侧的土压力时程曲线呈反向关系，说明基础在同一时间一侧受压，另一侧受拉。

The majority of piles are designed to support "active" loadings, that is to say, loads from upper structure are directly transferred to the pile foundation by the cap.

通常各类建筑工程中的桩基础主要是主动受荷桩，即上部结构的荷载通过承台传递给下部的桩基础，由桩土间的相互作用来分担上部结构荷载。

The structural layout and details of structural construction,such as isolation and slip support,viscous damper joint etc.

宿迁市府苑小区综合楼采用基础隔震技术进行结构设计，现介绍其设计要点，包括地下室、隔震层、上部结构的设计等，着重阐述结构布置方案与隔震支座、滑移支座、消能器的连接构造等。

Furthermore, isolation design can effectively decrease section size, reinforcement, engineering cost and story drifts of superstructures.

指出隔震设计可以有效减小上部结构的截面尺寸和配筋，降低工程造价以及减少上部结构层间位移。
