Through analyzing the test data of lateral displacement of the composite semitic walls with structural concrete columns under the action of horizontal loading , and combining the existent wall lateral displacement theory and calculate formulae , the approximate calculation method of lateral displacement of the semitic walls which are composed of brick and concrete was summarized 摘要通過對帶構造柱的組合抗震墻在水平荷載作用下側向位移的試驗數據分析,并結合己有的墻體側向位移理論計算公式,總結出了磚-混凝土組合抗震墻體側向位移近似計算方法。
The working principles are as follows : when the factors of the second order mechanics model are proper , the relative displacement , body to shell , is linear to the acceleration of shell . so the acceleration of the second order system is measured by measuring the relative displacement with the optical reflection displacement theory 其工作原理是:當二階力學模型的參數選擇適當時,力學模型中的質量塊相對外殼的相對位移與外殼的加速度近似成線性關系,所以采用光纖反射式位移傳感原理測量二階力學模型中的相對位移就可以達到測量二階系統加速度的目的。
