The Open System for Earthquake Engineering Simulation tG9C(D`G  
The Open System for Earthquake Engineering Simulation (OpenSees) is a software framework for simulating the seismic response of structural and geotechnical systems. OpenSees has been developed as the computational platform for research in performance-based earthquake engineering at the Pacific Earthquake Engineering Research Center. OpenSees is also the simulation component for the NEESit since 2004. Hiwij,1

我也在学习它的c++原代码，基本上算掌握了。但还没有真正改造过它的原代码。 f2Xn!]o  
实际上用TCL建模仍有很大的局限性，从面向科研的角度看，还是要掌握c++原代码。 jyyig%  
继续学习中........

opensees学习交流群:108677474，欢迎大家加入

英文的，呵呵还是很有用的

要学习！！！！！！！！！

好东西 !!谢谢了

唉，只会Fortran

什么是TCL建模，而且请问一下，在岩土方面是基于什么原理模拟的呢？

有人有着软件没有？上传共享一下撒

还以为是软件，不厚道

用于结构和岩土方面地震反应模拟的一个较为全面且不断发展的开放的程序软件体系，有原代码可以使用？？

大侠，听说您把源代码搞懂了，很佩服，能给点经验吗？我的qq: 745606860.恳请加大侠为好友
