In the first year, based on the information obtained in the preliminary experimental study on the proto type 20kN MR damper, a new 40kN damper with the maximum stroke of ±100mm was designed, manufactured, tested and confirmed to be the one with satisfactory stable load-deflection relations which can be adjusted by applying minor electric current. By installing this damper into a small simple one-mass model to represent a base-isolated building system, original semi-active control algorithms by project participants were investigated by means of shake table tests.In the second year, a larger scale shake table test was conducted. The model consists of a 2/3-scale steel frame rested on one-way roller bearings at the foot of the corner columns. Four natural rubber bearings were used to adjust the natural period of the system to be about 3.0 seconds. Instead of a normal passive damper, the 40kN MR damper is installed to perform semi-active control. Five different control algorithms proposed by each project participants were tested. The aim of each algorithm, i.e., to get less acceleration without causing greater displacement than the case of normal passive control, was found to be very successful. It was also confirmed that most experimental results and analytical ones showed good agreement.

第一年，根据20kN磁流变阻尼器原型初步实验研究的信息，设计、制造了一种最大行程为±100mm的新型40kN磁流变阻尼器，并进行了测试，确认该阻尼器具有满意的稳定的载荷-挠度关系，可以通过施加小电流进行调节。通过将该阻尼器安装到一个简单的单质量模型中来代表一个基础隔离的建筑系统，项目参与者通过振动台试验对原始的半主动控制算法进行了研究。第二年，进行了更大规模的振动台试验。该模型由一个2/3比例的钢框架组成，该框架位于角柱底部的单向滚子轴承上。采用4个天然橡胶支座将系统的自然周期调整为3.0秒左右。代替普通的被动阻尼器，安装了40kN MR阻尼器来执行半主动控制。测试了每个项目参与者提出的五种不同的控制算法。每个算法的目标，即获得更小的加速度，而不造成更大的位移，比普通被动控制的情况下，被发现是非常成功的。实验结果与分析结果基本一致。
