三角形板单元的局部效应分析

Analysis of Local Effect of Triangular Plate Element

根据三角形权单元内部力矩平衡的原理，建立了任意荷载激励下三角形权单元的局部效应计算模型，推导了相应的计算公式，并对一悬臂板在动荷载激励下的动内力进行了局部效应分析．计算结果表明，考虑局部效应后可以使动内力计算结果更为精确，

A new computational model of partial effect for triangular plate element under arbitrary excitation is established by the moment balance principle inside element The corresponding computational formula is also obtained. By analyzing dynamic response of cantilever plate under different excitation, it has been found that the results have become more accurate when local effect is considered.
