In this study a new device with hardening type hysteresis is proposed, combining fluid damper and displacement controller. This system is effective to control the response of buildings when it is installed in the structures. Two major objectives are described in the following.1. To develop a dual design method to improve habitability under a moderate earthquake and prevent the spread of damage under severe earthquake:In this system when subjected to a moderate earthquake, installed damper consuming energy decreases the response of buildings and improves the habitability. When subjected to a severe earthquake, the displacement controller restrains excessive story displacement while fluid damper consumes energy. This means that the building structure is change from the seismic control system with fluid damper to the normal earthquake resistant system with stiff braces. From this effect spread of structural damages are prevented. The effectiveness of this proposed system is verified by sh … More aking table tests installed in Tohoku University and furthermore investigated by analyses for reinforced concrete buildings considering various conditions.2. To develop a design method to control the response story displacement of a building under severe earthquake:In this system when subjected to severe earthquake, the displacement controller restrains excessive story displacement of the building and controls the distribution of story displacement as designed one. Using this system, unified distribution of story displacement can be obtained by restraining excessive local displacements caused by the irregularity of stiffness and / or strength distribution in a building or the contribution of higher modes. In this study the design method is proposed to calculate necessary damper quantity by energy response, equalizing input energy from earthquake and consuming energy by structures and damper at design displacement level. The effectiveness of this design method is verified by shaking table tests installed in Tohoku University and furthermore investigated by analyses for reinforced concrete buildings considering various conditions such as the distribution of stiffness and / or strength and earthquake characteristics.

在这项研究中，提出了一种具有硬化型磁滞的新装置，结合了流体阻尼器和位移控制器。当该系统安装在建筑物中时，可以有效地控制建筑物的响应。两个主要目标描述如下： 1．开发双重设计方法，以提高中度地震下的可居住性并防止严重地震下的损害蔓延：在该系统中，当遭受中度地震时，安装的耗能阻尼器降低了建筑物的响应并提高了可居住性。当遭受严重地震时，位移控制器抑制过度的楼层位移，而流体阻尼器则消耗能量。这意味着建筑结构由采用流体阻尼器的抗震系统转变为采用刚性支撑的普通抗震系统。通过这种效果，可以防止结构损坏的蔓延。该系统的有效性通过东北大学安装的sh … More aking table 测试得到验证，并进一步通过考虑各种条件的钢筋混凝土建筑分析进行研究。 2．开发一种控制强震下建筑物响应层位移的设计方法：在该系统中，当遭受强震时，位移控制器抑制建筑物过度的层位移，并控制层位移按设计分布。使用该系统，可以通过抑制由于建筑物内刚度和/或强度分布的不规则性或较高模态的贡献而引起的过度局部位移，从而获得楼层位移的统一分布。在本研究中，提出了一种设计方法，通过能量响应来计算所需的阻尼器数量，平衡地震输入能量以及设计位移水平下结构和阻尼器消耗的能量。该设计方法的有效性通过东北大学安装的振动台试验得到验证，并进一步通过考虑各种条件（例如刚度和/或强度分布以及地震特性）的钢筋混凝土建筑分析进行研究。较少的
