以梁单元的局部效应修正为例 ,探讨了结构动力分析的局部效应问题 ,计算结果表明 ,考虑局部效应可以使动内力计算结果更为精确 .
WT5BZ]The modification formulation of beam element under arbitrary excitation has been put forward. By analyzing dynamic response of the structure under different excitation, it has been found that the results have become more accurate when local effect is considered. When analyzing dynamic response of large scale complicated structure, the computational model can be greatly simplified by considering local effect, moreover, the computational precision has also been greatly increased.
