摘　　要：采用Ansys分析模型范围对加筋板极限强度的影响,对比计算表明:单轴压缩载荷作用下,采用3种模型范围计算加筋板极限强度均能得到较好结果;双轴压缩载荷作用下,三弯单跨模型与双弯双跨模型计算结果吻合较好,单弯单跨模型计算结果比上两种模型范围结果偏大10%。The influence of the model range upon ultimate strength of the stiffened plates is studied by Ansys .The compara-tive analysis with the numerical results showed that , under the axial compressive , all the three kinds of model range could get a proximity result of the ultimate strength;while the bi-axial compressive , the results of three bay /one span model and two bay /two span model are proximity , but the result of one bay /one span model is 10%lager than the above models .
