rotational restraint meaning in Chinese

旋转约束

During the full scale model comprising an area of 28 m2 not only the conventional loading capacity tests were taken but also the rotational restraint was tested , which will provide valuable data to some similar structure members design
进行面积约28m ~ 2的足尺模型的承载力试验时，同时对蒙皮支撑的檩条进行了抗扭刚度试验，为今后同类檩条设计过程中扭转刚度的取值提供了参考。
A quadratic equation with one variable for two - story frames and a cubic equation with one variable for three - story frames are derived from which the rotational restraint provided to each column may be solved and the effective length factors can then be determined by the traditional formula or tables
对于两层框架，通过求解一个一元二次代数方程得到各柱柱端的转动约束；对于三层框架，通过求解一个一元三次代数方程，得到各柱柱端的转动约束。进而由传统公式或规范附表得到各柱的计算长度系数值。
