考虑剪切变形及转动惯量的H型钢梁自由振动
Free vibration of H-shape steel beam considering shear deformation and rotational inertia
摘要
Abstract
With three kinds of typical hot - rolled H - shape steel section free beam as research objective, the difference of former third - order free vibration frequency with different slendemess ratio was analyzed by elementary beam theory model and higher beam theory model which considering the shearing deformation and the inertia effect. The applicable conditions of free vibration analysis by the elementary beam theory on H - shape steel beam is obtained. This conclusion provids reference for dynamic analysis and the dynamic design.关键词
