| 摘 要： | 混凝土框架结构可用梁单元,也可用实体单元进行数值分析,但两种单元计算结果之间存在一定差异;文中用ANSYS中Solid单元和Beam单元对一个简单的框架进行应力或内力计算,指出两者之间计算差异的根源,并结合新颁布的DL/T 5057-2009《水工混凝土结构设计规范》论述怎样用Solid单元计算出的正应力和剪应力进行结构承载能力分析。

| Abstract: | The concrete frame structure can be analyzed in values by applying beam unit or solid unit. But, difference between the calcu- lating results of two units must be available. In this paper, stress or internal force of a simple frame is calculated by applying solid unit and beam unit in ANSYS. Sources of difference between two calculating results are pointed out. In combination with the newly-issued Design Code for Hydraulic Concrete Structures, DL/T 5057-2009, how to analyze the structural bearing capacity by applying positive stress and shear stress derived from calculation through solid unit is described. |
