小弟对ansys不是太熟练，做完硕士课题后，感觉学好ansys还是必要的，再说离开学还有一段时间，小弟就较为系统地学了下ansys，所用参考教材为：《Algor、Ansys在桥梁工程中的应用方法与实例》，《ANSYS.结构有限元高级分析方法与范例应用（第一版）》，《ANSYS.结构有限元高级分析方法与范例应用（第二版）》，《ANSYS土木工程应用实例》，《ansys高级工程有限元分析范例精选——祝效华》。这些教材，基本上学习ansys最好的教材了，但遗憾的是这些书中都有错误。如能将这些错误改正，对自己和别人都大有益处。 这些书中的错误有些地方小弟可以自己看出来，有些地方就无能为力了，在此，特向各位师长，学长，同仁请教。 首先，将自己发现并改正的例子发出来，供大家讨论。 《ANSYS.结构有限元高级分析方法与范例应用（第一版）》第8章悬索拱桥地震荷载响应分析有错误。本人作了改动，模型和地震响应分析的完整命令流： FINISH /CLEAR /FILENAME,bridge harmonic analysis /TITLE,bridge harmonic analysis /PREP7
