In the recent years, the climate change is cause of the important changes for human. In which, strutural analysis is changed too. In this paper, the author presented the following problems: - Determination of fuzzy loads acting on Strutures is caused by climate change
- Mean safety probability of Structure subjected to fuzzy load is determined on a interval
- Schema of fuzzy analysis of Structure and extended interference model
- Algorithm for the determination of the deterministic input from fuzzy input
- Algorithm for frequency histogram of output. To inlustrate for proposed problems, a sample example is considered.
