The invention relates to a concrete-filled steel tube power transmission tower natural vibration period determination method and device. The method comprises the following steps: determining an adjustment coefficient corresponding to a concrete-filled steel tube power transmission tower according to concrete pouring height of the concrete-filled steel tube power transmission tower; and determiningthe natural vibration period of the concrete-filled steel tube power transmission tower according to the adjustment coefficient corresponding to the concrete-filled steel tube power transmission tower. The method can obtain the adjustment coefficient corresponding to the concrete-filled steel tube power transmission tower under the condition of considering the concrete pouring height, and furthermore can obtain the natural vibration period of the concrete-filled steel tube power transmission tower according to the adjustment coefficient corresponding to the concrete-filled steel tube power transmission tower, so that compared with the prior art, the method can obtain more accurate natural vibration period.
Description
technical field [0001] The invention relates to the field of technical design and construction of electric power engineering, in particular to a method and a device for determining the natural vibration period of a steel pipe concrete transmission tower. Background technique [0002] High-voltage, large-capacity, long-distance power transmission is the focus of power grid construction. In order to meet this development requirement, transmission technologies such as multi-split, large cross-section conductors, multiple circuits on the same tower, UHV, and large spans have been widely used. The resulting height of the tower continues to increase, and the load on the tower continues to increase. As the height and load of the transmission tower continue to increase, the advantages of the steel tube concrete transmission tower will become more and more obvious compared with the all-steel structure transmission tower. However, there is insufficient research on the dynamic charac...
