SETAF2018: Advanced Liquefaction Analysis and Reporting Solutions

We provide fast and reliable liquefaction analysis solutions fully compatible with current engineering standards to build safe structures in seismic risk areas. Your projects are now safer and more traceable thanks to professional liquefaction analysis methods developed to maximize soil safety.

High-Precision Evaluation with SPT Data

SETAF2018 meticulously manages liquefaction analysis processes using SPT (Standard Penetration Test) data based on widely accepted regulatory methods. The software performs N1,60f corrections based on fine-grain content and executes high-accuracy liquefaction calculations using the SPT profile from the selected borehole. Within the scope of simplified liquefaction analysis, the software automatically evaluates criteria for sand and gravelly soils, while Adapazari and Ishihara criteria are systematically queried for fine-grained soils. This comprehensive module evaluates all critical layers up to a depth of 20 meters from the surface and reports the calculated safety factors.

Advanced Liquefaction Control in Improved Soils

In soils improved with rigid column systems such as jet grouting, deep mixing, concrete piles, or micropiles, liquefaction analysis is conducted using the Baez (1995) method within the framework of soil-column interaction. In this module, SPT-based liquefaction analysis data is re-evaluated based on the earthquake load-sharing capacity of rigid columns, known as the Kg reduction factor. This approach, among the advanced liquefaction analysis methods, allows for the analysis of both compatible and non-compatible deformation states to reach the most accurate liquefaction calculation results. This infrastructure, which works integrated with simplified liquefaction analysis, provides economic design solutions even in complex geotechnical conditions.

Post-Liquefaction Settlement and Decision Criteria

Following the liquefaction analysis, the software models soil behavior by calculating surface settlements that may occur due to seismic loads using the Tokimatsu and Seed (1987) method. During the liquefaction calculation, parameters such as liquid limit (wL ≤ 33%) and plasticity index (Ip < 15%) for fine-grained soils are monitored according to Adapazari Criteria. In the simplified liquefaction analysis module, the probability of the liquefied layer reaching the surface is presented graphically using the Ishihara criteria. These liquefaction analysis methods, which can be diversified based on different earthquake scenarios, generate technical documents that accelerate the administrative approval processes of your projects.

Professional Reporting and Dynamic Data Management

Using SETAF2018 for SPT-based liquefaction analysis eliminates the burden of manual calculation tables and complex formulas. The systematic liquefaction analysis methods offered by the program are managed dynamically through tables updated instantly with variable parameters. Every liquefaction calculation performed is transformed into transparent and queryable reports supported by open equations, tables, and visual cross-sections. You can export simplified liquefaction analysis results and all technical details to Excel format with a single click for use in your specialized engineering studies. These reports, derived from SPT-based liquefaction analysis data, provide a strong technical foundation for audit units.
