单跨超静定梁在均布荷载作用下的弹性力学解

The Elastic Mechanics Solution of Hyperstatic Beams with Single Span under the Action of Even Load

根据弹性力学平面问题的基本理论 ,采用半逆解法 ,求出了一端固定一端铰支单跨超静定梁在均布荷载作用下的应力和位移 ,并由此说明了材料力学解的精度和适用性 .

By means of the basic theory of plane problem in elastic mechanics and by using half adverse solving method,this paper calculated the stresses and displacements of hyperstatic beams fixed at one sides and simple supported at another side under the action of even load.The precision and applicability of solutions of material mechanics were set forth from above solutions.
