Calculation problems for tower vessels
Thread Content
When calculating tower equipment, the principle for distributing seismic forces is a inverted triangular distribution. I’m asking a senior for help – what does \"inverted triangle distribution\" mean?
It is along the vertical direction from the ground level; the higher the particle is, the smaller the vertical seismic force.
The horizontal seismic force is calculated using the base shear method; the higher the particle, the greater the corresponding horizontal seismic force.
The second and third floors should be considered together; 1. The distribution of vertical seismic forces follows a inverted triangular principle, with smaller values at the bottom and larger values at the top； 2. The vertical seismic force is greater at the bottom and smaller at the top, because the seismic force at a certain calculation section is the sum of the seismic forces from all areas above that section.
