MATRIX ALGEBRA ALGORITHM OF STRUCTURE
RANDOM RESPONSE NUMERICAL CHARACTERISTICS*
Abstract: A new algorithm of structure
random response numerical characteristics, named as matrix
algebra algorithm of structure analysis is presented. Using the
algorithm, structure random response numerical characteristics can easily be got by directly solving linear matrix equations rather than structure motion differential equations. Moreover, in order to solve the corresponding linear matrix equations, the numerical integration fast algorithm is presented. Then according to the results, dynamic design and life-span estimation can be done. Besides, the new algorithm can solve non-proportion damp structure response.
Key words:
Matrix algebra algorithm Structure random Response numerical characteristics
Numerical integration fast algorithm Non-proportion damp
