Structural assessment is a very hot topic in earthquake-prone countries since the evaluation of building stock is necessary for existing aged or shady buildings, after a major earthquake, or after major seismic code changes. Many different techniques are proposed in this context, but there are very limited studies on applying assessment methods using internet-based technologies even though web-based approaches will have many advantages such as formation of a building condition database, integration with other cloud services (like GIS), implementing hardware capabilities (taking photos, voice recording, vibration measurements by accelerometers, geolocation by GPS. . . etc.), automated simple analysis and reporting, access and applicability to many users and large geographic areas, and mobilization of the process using mobile platforms (smartphones and tablets). The structure of the developed on-line system has three root modules; client, analysis server, and database servers. The system performs two levels of assessment. In this study, existing assessment methods have been implemented to the web-based analysis tool as well as new improved assessment techniques are proposed. The first method evaluates a building based on simple observable parameters (such as number of floors, window sizes. . . etc.) that can be entered by residents and non-technical people as well, while the second level requires a more comprehensive data entry including column locations and column geometric dimensions. The first level method has been improved by adding addiv tional evaluation parameters and increased interaction between these parameters such as soil condition and building height (or period). The second developed technique is more advanced and has minimal structural analysis while approximately mimicking a full three-dimensional finite element analysis. The developed simplistic method and the advanced method are both experimentally implemented to the internet and results are correlated with other first level and SAP2000 analyses for randomly generated buildings and successful correlations were obtained.
