Selection of the maximum value of the horizontal seismic influence coefficient for towers in earthquakes of magnitude 6
Thread Content
When designing towers, I would like to ask: when the seismic design intensity is 6 degrees, according to GB50011-2010, should the maximum value of the horizontal seismic influence coefficient be set at 0.04? Thank you!
When designing towers, it’s sufficient to use the standards applicable to towers; it has nothing to do with GB50011-2010, right?
Thank you for your reply. The standards for towers refer to GB50011-2010; therefore, when the inclination angle is 6 degrees, SW6 is used to calculate the tower. I’m wondering whether I should consider the maximum value of the horizontal seismic influence coefficient as specified in GB50011-2010 and use 0.04, or whether I should ignore seismic effects altogether

If it’s 6 degrees, according to current standards, it is not considered as an earthquake load; however, the standards represent only the minimum requirements. You need to decide based on the importance and level of risk associated with your tower； Based on my design experience, a damage level of 6 degrees is quite low; wind load becomes the main issue here. The standards take into account earthquakes of magnitude 6, but the probability of tornadoes occurring is extremely low
Are there still areas that only need to be designed according to the six-degree principle? ? ?
