In the case of invariable of outrigger belt and changing the vertical positional arrangement,the effect on structural inner force,natural vibration period and sidesway were discussed.

分析固定加强层水平伸臂的位置不变,改变环带的竖向位置,研究环带的竖向位置对高层框筒结构力学性能的影响。

A method of sidesway controlling by horizontal loads on high-rise frame-core wall structures was discussed and mechanism of reducing structure sidesway with horizontal outrigger and belt elements had been analyzed.

探讨了高层框架-核心筒结构在水平荷载作用下的侧移控制方法,分析了设置水平伸臂构件和环带构件对减小这类结构侧移的作用机理。

Sometimes belts beam or truss are set up when necessary.

针对现阶段国内外水平伸臂的研究较多,而环带对结构的影响分析较少,论文通过工程算例分析研究了伸臂和环带对结构在水平荷载作用下的力学性能,着重分析了环带在加强层中的作用。

This research further proves the existence of low resistivity belt zones in oil layers.

由于阵列感应资料可以提供地层电阻率的径向变化趋势,该文针对同一口井同一类液体性质储层的阵列感应测井(HDIL)资料所呈现的完全相反曲线数值排序现象进行深入分析,进一步证实了油层中低阻环带的存在,为进一步建立油水层的识别标准提供了依据。
