Abaqus中B31梁单元无法混凝土塑性损伤模型？
如题，使用做一个框架的抗震分析，梁柱均采用B31单元，混凝土使用C30损伤模型，但报错The *concrete damaged plasticity option is not available for beam-type elements with shear stress。换成最简单的悬臂梁模型，相同的材料本构仍然报错。查询软件说明书，有这样一句话：ABAQUS offers a variety of elements for use with the concrete damaged plasticity model: truss, shell, plane stress, plane strain, generalized plane strain, axisymmetric, and three-dimensional elements. Most beam elements can be used; however, beam elements in space that include shear stress caused by torsion (i.e., not thin-walled, open sections) and do not include hoop stress (i.e., not PIPE elements) cannot be used.。说明B31梁单元无法使用损伤模型吗？但看了很多论文都是明确指出二者可以共同使用的，求高手解释！！

2017版说明书里这样写：Abaqus offers a variety of elements for use with the concrete damaged plasticity model: truss, shell, plane stress, plane strain, generalized plane strain, axisymmetric, and three-dimensional elements. Most beam elements can be used; however, beam elements in space that include shear stress caused by torsion and do not include hoop stress (such as B31, B31H, B32, B32H, B33, and B33H) cannot be used.。明确指出B31单元无法使用，那我看的论文里是怎么算的啊？难道老版本允许吗。论文为：上海中心大厦抗震性能分析和振动台试验研究_蒋欢军

您好，我的课程里面讲解了利用B31梁单元来做三维框架结构，包含了时程分析以及pushover分析，当然框架里面是配有钢筋的。
