摘要: |
应用数值方法模拟了边梁的效应,给出了一个边梁的弯曲刚度与扭转刚度的配置公式,从而消除了板的挠度、弯矩、剪力等随边梁刚度的增大而增大的不合理现象,并对忽略边梁的抗扭能力所导致的误差进行了定量研究。 |

Numerical simulation of the responses of boundary beams |
|
Abstract: |
The responses of boundary beams are simulated numerically and the relationship between the bending and torsional rigidity of the beams is presented.With the relationship,the irrational phenomena that the displacements,moments and shearing forces of the plates increase as the rigidity of the beam increases are avoided.The errors due to disregarding the torsional rigidity of the beams are analyzed as well. |
