[记事]ETO, etabs to opensees, Etabs 转 OpenSEES 小工具及OPENSEES的实例教程们，现在有一些用户在使用，开发它感到很开心，可以与大家学生联系在一起，虽然不能在高校与研究生们交流，但是可以在工作之余业余搞点小研究，还是开心的，小研究就包括这个ETO了。现在，经过我与FMK的介绍，FMK把我们的ETO下载方法及实例教程的地址放在了PEER,opensees的官网，我感到非常地高兴，终于看到我的名字在OPENSEES的官网上了，呵呵。

ETO(ETABS To OpenSees) developed by Dr. Dino Chen , is a pre-process and post- process program for OpenSees. Building model and checking analysis result can proceed in the integrated user interface of ETO. The operation of ETO is entirely based on 3D environment, and the graphic display can change between plane view, elevation view and three-dimensional view. It is different from other pre-process program for OpenSees in that ETO can import s2k(Sap2000 v6) file generated by ETABS and there is no need for users to relearn the basic methods of building model. In the respect of pre-processing, the major functions of ETO include:

(1) Definition of frame section. Users only need to input the relative arguments such as sectional dimension, steel bars area, number of fibers, element types, to realize the dividing of cross section, the definition of frame element easily.

(2) Check of model information. Users can query the information such as nodal label, label of element, local axes of element, diaphragm, restraint, nodal load, load of element conveniently.

(3) Settings of analysis and recorder arguments. Users can choose different analysis types(modal analysis, pushover, time history analysis, multiple support excitation and so on), control cases(load control case, displacement control case) and analysis results to be recorded(nodal displacement, force of element and deformation of section) according to the actual needs.

In the respect of post-process, ETO can show the analysis results of OpenSees visually, including nodal displacement, deformation of section and modal shapes.
