- The structural statically determinate characteristic is advantageous to avoid additive stress to improve construction quality because of coercive assemblage actions are avoided.
- Additional stress cycles may result under some condition.
- Such a structure, with many circular soldering seams and its bowrdary additive stress in the cone body, increases the insecure factors and the work of melding and ray inspection, and its outline is not so elegant as wess.
- Meanwhile,through the grey forecasting of equidistant data sequent,GM(1,1) modeling is established,while the data analysis about the relationship between additive stress and time is made.
- The structural statically determinate characteristics can avoid coercive assemblage actions, so that additive stresses were avoided and construction quality was improved.
