【摘要】 本文分别采用协调元和非协调元对连续梁桥进行空间应力分析,对其计算应力值进行了分析比较;实例计算分析表明,对横力弯曲为主的构件以三维实体单元进行空间有限元计算时,采用协调元的计算数值与理论值相悖,而采用Wilson非协调元可得出与理论值较为吻合的数值更多还原

【Abstract】 In this paper, the spacial stresses analysis of bridges are carried out by using both the conforming element and non-conforming element respectively for comparison. The numerical example shows that the stresses of the structure, subjected mainly to shear-bending, computed by using the three-dimensional conforming element are different from the analytic values, but those computed by using the three-dimensional Wilson non-conforming element are close to the analytic values.更多还原
