Define flexibility coefficients.
Answers
Explanation:
For systems with one DOF, to move a mass m with a distance x a force F is required, that is, F = kx. Similarly, if a force F is applied to the mass, the deflection will be x = (1/k)F. If a is defined as the inverse of k, then x = αF, where α is the flexibility coefficient of influence.
Answer: Flexibility coefficient refers to the displacement at coordinate i due to unit force at coordinate j in a structure.
Explanation:
A famous dam expert in Swiss, Lombardi first proposed the “flexibility coefficient” concept for the first time during researching the Kolnbrein dam heel cracking.
According to him, the calculation equation of flexibility coefficient was given as follows. =2/, where is the developed area of the arch dam in upstream face, m2; is the earthwork volume of dam, m3; is the arch dam height, m. and flexibility coefficient written above was used to assess the arch dam safety.
Now lets see the benefits of flexibility coefficient ,it is popularly used to implement the macro evaluation of shape, safety, and economy for arch dam. The relationship between influencing factor and flexibility coefficient is analyzed by means of partial least-squares regression based on a large number of relative instance data,
