Analytical Model Of A Simple Supported Beam With Variable Section Subjected By A Moving Load
Advanced Materials Research(2011)
摘要
The variable section influence on the vibration of a simple supported beam under the action of a moving constant concentrated force is investigated in this work. The technique is based on analytical approach with the assumed model method and the numerical approach of Newmark method. Comparisons with the results between vary-section beam and constant-section one indicate that it is a wise approach to economizing materials and lightening the load of gravity by applying vary-section beam on the condition that the maximum stress cannot change dramatically.
