OpenSEES是一个优秀的地震工程开源软件，但是很多使用者在前后处理方面总会遇到不便，我在做剪力墙低周往复试验与足尺钢框架结构的数值分析的时候也遇到这个问题。我是如何解决的呢？我是采用面向对象语言如Delphi，VC++，VB这一类软件去实现。通过本科时候的百步梯科研计划的训练，对计算机图形学也有所了解，采用面向对象语言编前后处理的好处是显示速度快，实时显示，方便调整。虽说前后处理不是计算分析的核心，但是前后处理是软件推广的主要因素呀。我总结一下我用Delphi做剪力墙试验的前后处理的过程：
OpenSEES is an excellent open source software of earthquake engineering, but many users of it have some inconvenience of the prep and post factors. I found the inconvenience when I analyzed the shear wall cylic test and full scale steel frame test. How can I solve the proble?? I choose the OPP language to do that, such as Delphi, VC++ and VB. After the trainning of the 100steps science project, I am so good at comptuer graphics. The avantages of  OPP program are fast display, real time, change easily. The prep and post system is not the core of analysis, however, it's the important factor of  software spread. Now, I has some conclusions of how to make the post programe when I analyze the shear wall.
（1）创建结构要素的数据结构与对象； Create data and objects of the structure elements;
（2）创建结构文本导入程序； Create input text file sub program;
（3）编制结构在OpenSEES里面输出的信息格式； Define the format of OpenSEES output file
（4）编写实时文本读取子程序； Create real time text file reader
（5）编写结构单元及应力云图绘制规则； Define the drawing rules of the structure elements nad stress strain color figures
（6）选取图形绘制系统，建议平面采用DirectX，空间采用OpenGL； Choose graphics system, 2D use DirectX, 3D use OpenGL
（7）调整颜色，粗细等要素，使程序美观； Fix the color, pen width, make the post system as beautiful as you can
（8）调入时间功能，实现动画显示。Set the clock component, change to be the real time animation.
编制后处理程序，可以方便检查你的模型是否正确，结果可视化后可检查分析结果，查看规律。还有一点，让你的论文绵上添花。以下是我的剪力墙的后处理界面，正式论文在十二月的《世界地震工程》发表。
When the post system is finished, it's very useful for checking, not only to check the building errors, but also to find the rules from the results, even more, make your paper much more professional. This is the Post window of my shear wall test simulation, the paper will be published in December.
