Question: Elastic_foundation Multi-span Euler-Bernoulli Beam_(three-span)

Hi Everyone!

Considering the Figure (3_span_elastic_support) given by the paperwork ( I try to build the matrix based on the following references:
- BOOK: Moving Loads - Dynamic Analysis and Identification Techniques_ Structures and Infrastructures Book Series, Vol. 8-CRC Press (2011)

My questions are:

- when I consider the coefficients kt = 4.881*10^9 and kr= 1.422*10^4 the following message appears. What Is the limit of MAPLE? 10^6?

- Because of this "fsolve" take to a long time to compute the values. If the message above appears I can trust in the "fsolve" values?

Please Wait...
