โœฆ Synopsis


A BSTRA CT Two solutions for the title problem are presented in this study: (i) an exact approach using the Bernouilli theory of vibrating beams; (iO a finite element solution using classical beam elements. Excellent agreement is achieved for all cases considered. Experimental results are also presented using a clamped portal frame model specially designed during this investigation, and it is shown that the measured fundamental frequencies are in rather reasonable agreement with the analytical predictions.
