Dear Nilutpal Bora

You can visit the link below, the programs were made by Prof. Nozomu Yoshida, Tohoku Gakuin University. All Softwares are free.

Here, the list of the programs:

-DYNEQ: Equivalent linear earthquake response analysis of ground

-YUSAYUSA: One dimensional seismic response analysis of ground based on effective stress 

DYNES3D: Truly nonlinear one dimensional seismic response analysis of ground with three directional input

DYNEQ is similar to SHAKE, NERA, and EERA. Detail can be found in the link.

Hope this help.

Thanks Saifuddin.. for your reply.. I will check it out surely
