Base on the highway and bridge design code, the dimension of rubber bearing that was used in test has been decided. Considering the limit of the upper load of bridge , compression stress , buckle phenomenon ,and lateral deformation of rubber bearing in the code can decide the dimension of rubber bearing .Its dimension is 15cm*15cm*2.7cm ,and the thickness of reinforced steel plate is 1mm . In this scaled model test, we put the rubber bearing on the top of two columns, but the one on the left column has a piece of PTFE.
The design of shear key is also based on the highway and bridge design code .We use two steel bars instead of the real shear key. There are two regulations about the gap in the code .The gap on lateral direction has no space , in other words , the girder of slab and the shear key are close together. The gap on longitudinal direction should be larger than the maximum elastic deformation of rubber bearing. Because we would like to know the behavior that the slab slides and impacts the shear key, and how much force passes from the shear key to columns, we decide to set longitudinal gaps about 2cm.
In the test, there were four earthquake time history records to be used, including El Centro, Kobe, TCU068, and ARTIFICIAL-TCU068. The TCU068 time history records was recorded at a station near the fault in 921 Chi-Chi earthquake, and the ARTIFICIAL-TCU068 time history was modified to be compatible with the acceleration spectrum in code. Every time history record should be modified the time interval to satisfy the relationship between the prototype and scaled-model. The test model will be performed two tests, including shaking table test and pseudo dynamical test.

關於高速公路和橋設計代碼的基礎,在試驗中使用的橡膠舉止的度被決定了。在代碼中考慮橋,壓縮壓力,扣環現象,和橡膠舉止的側面的變形的上層的裝載量的限制能夠決定橡膠舉止的特點 . 它的度是 15 cm*15cm*2.7cm,被加強的鋼鐵盤子的厚度是 1 毫米。在這次被測量的模型試驗中,我們把橡膠舉止放在雙列的頂部上面,但是在左專欄的一個有一塊 PTFE。
剪鑰匙的設計也可以 . 我們使用的高速公路和橋設計代碼為基礎二根鋼鐵橫杆取真的剪鑰匙代之。關於在代碼中的差距有兩個條例在側面的方向上的 . 差距沒有空間,換句話說,厚平板的梁和剪鑰匙一起是接近的。在經度的方向上的差距該是比橡膠舉止的最大橡皮帶的變形更大的。因為我們想要知道厚平板滑動和影響的行為剪力鑰匙,多少力量從到專欄的剪力鑰匙通過,我們決定設置經度的差距大約 2 厘米。
在試驗中,有四段地震時間歷史記錄被使用,包括 El Centro,神戶, TCU068 和人造物-TCU068。TCU068 時間歷史記錄在 921 中的缺點附近以一個站被記載引起性欲的東西地震,人造物-TCU068 的時間歷史被修改在代碼中与加速范圍協調。每次歷史記錄該被修改滿足在原型之間的關系的時間間隙和規模模型。試驗模型將被實施兩次試驗,包括震動桌子試驗和假動力的試驗。
