#Log 28Nov2021. "README.md in main" included the title of the journal, DOI and the publications date.

16Nov2021. The manuscript was published on a journal, Bulletin of Earthquake Engineering.

05Feb2021. Three files were updated: "info_Comp_Fragility_NonStructural_Accel.m", "info_Comp_Fragility_Structural" and "info_num_Components_Structural.m".

The folder contains MATLAB codes that computes the following values that are the results of seismic loss assessment of seismically isolated buildings with SCBF designed by RI=2 and TFP-1 based on Conditional Spectra approach (notations are explained in the manuscript):

• Loss vulnerability functions
• Expected annual loss (EAL)
• Expected Loss (=EL) Over Time (=t)

To implement this example code, you need to download the data of results of nonlinear seismic response analysis (i.e., multiple stripe analysis; Jalayer, 2003) from the following link:

https://drive.google.com/file/d/1pNAoIicndCVjONx4P9fMqTAlJawJbsfy/view?usp=sharing

The downloaded data (i.e., a folder, after extraction of zip file, "Response_analysis_data_CS_SCBF_RI2.0_Iso1_ASCE16") of results of seismic respone analysis should be located to the folder in the same place as the matlab files are located.

The zip file should be extracted to get a folder that contains data. The data is the results of analysis of seimically isolated building with SCBF (superstructure is designed per RI=2.0) and with the smallest required isolators (TFP-1) based on ASCE7-16 (2017) seismic design standard.

Please note that one of the MATLAB file "fn_mle_pc.m" used in this folder was obtained from the data set that is associated with the following journal article: Baker JW. (2015). “Efficient analytical fragility function fitting using dynamic structural analysis.” Earthquake Spectra, 31(1), 579-599.
