梁的两端往复位移加载,最大位移是40mm,加载步如下,钢筋采用桁架单元,梁柱采用三维实体单元。网格单元大小50mm,荷载条件是:柱的上下端为固定铰支即U1=U2=U3=0,UR1=0,柱顶受10N/mm2的均布压力,分析步:时间长度为1,最大增量步数为200,初始增量步大小为0.001,最小1e-7,最大是1。相互作用:梁柱接触截面采用tie,内部钢筋采用embeded。混凝土本构关系中,混凝土损伤塑性数据为:

导致出现错误:
Time increment required is less than the minimum specified
Abaqus/Standard Analysis 由于出错而退出 - 如果 消息 文件存在, 请从该文件中获得可能的错误消息.
请问以上是什么原因导致的啊?上面的警告看不懂什么意思!!!敬请高手指教!!!! |
