如題，使用做一個框架的抗震分析，梁柱均采用B31單元，混凝土使用C30損傷模型，但報錯The *concrete damaged plasticity option is not available for beam-type elements with shear stress。換成最簡單的懸臂梁模型，相同的材料本構仍然報錯。查詢軟件說明書，有這樣一句話：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.。說明B31梁單元無法使用損傷模型嗎？但看了很多論文都是明確指出二者可以共同使用的，求高手解釋！！
