Radar is a radio device that uses radio waves to determine the location of objects. To avoid interference from surrounding buildings, radar towers are typically as high as 100 meters.
Approximately m, due to the performance requirements of the radar, the fundamental frequency of the radar tower must not be less than 1.0 Hz. Through extensive calculations and analysis, some significant improvements have been identified.
Fundamental frequency patterns of high radar towers. Radar towers are extensively applied in modern times, both at sea and on land, in traffic and other applications, used for定位
Speed measurement, search, etc. Meanwhile, the seismic response of the radar tower was analyzed using the response spectrum method, time history analysis, and random vibration method. Calculations
The results indicate that the radar tower meets the seismic code requirements for inter-story displacement.
Tower structure:
The entire steel tower is mainly composed of three major parts: the tower head, the tower body, and the tower legs. If it is a guyed tower, the guy wire section is also added. The tower head extends upwards from the tower legs to the tower frame section.
Sharp change (dashed line) above this section is the tower head. If there is no sharp change in cross-section, the portion above the bottom chord of the lower crossbar is also considered the tower head. Tower leg
Above the base, the section of the tower frame is called the tower leg, the tower body, and the part between the tower leg and the tower frame is called the tower body.
