what is the reason behind that and what remedi taken to stable the structure

You are welcome. Simplest way to learn something new to model is to take an example out of the book, do the model and compare the results. If your results are same as that of the book example, you have done a good job. Here are some tips: 1) Top and bottom members need to be modelled and designed as continuous members. 2) Make sure your unbraced lengths are correct. 3) Manually resolve wind and snow loads on trusses. In that way, you will minimize any chances of error in load application. 4) Manually check at least dead weight reactions and member forces. If they match, you can trust your model. Hope that helps. Thanks.
