AI Algorithms & Methods for Seismic Safety
Neural Networks (NN), including Radial Basis Function Neural Networks (RBFNN), are inspired by the human brain and excel at pattern recognition, making them ideal for predicting structural responses and optimizing control strategies.
Fuzzy Logic Controllers (FLC) handle ambiguity and imprecision in seismic data, adapting control actions based on approximate reasoning. They are particularly effective in real-time scenarios with uncertain measurements.
Genetic Algorithms (GA) use principles of natural selection to optimize structural designs and control measures, leading to robust solutions over time by iteratively improving parameters.
Support Vector Machines (SVM) are powerful for classifying seismic risk levels and predicting structural reactions, trained on historical and simulated data for optimal mitigation.
Reinforcement Learning (RL) algorithms learn optimal control strategies through iterative interaction with environments, dynamically adapting to seismic inputs for real-time adjustments.
Long Short-Term Memory (LSTM) networks are a type of recurrent neural network (RNN) capable of handling sequential data and predicting future steps, crucial for decentralized control systems in high-rise buildings.
The integrated RBFNN-NTSMC (Nonsingular Terminal Sliding Mode Controller) combines RBFNN's approximation capabilities with NTSMC's robustness to provide an adaptive, highly effective control strategy for structural vibration reduction.
Categories of Structural Control Devices
Passive Control Devices: Function independently, absorbing vibrations without external power. Examples include Tuned Mass Dampers (TMD) and Base Isolation. While cost-effective, their efficiency is limited to specific frequencies.
Active Control Devices: Require external power and advanced technology for real-time adjustments. Active Mass Dampers (AMD) are more effective than TMD but have high power consumption and potential reliability issues.
Semi-Active Control Devices: Combine features of both passive and active systems, using minimal energy. They adapt to changing conditions and include MR Dampers and Controllable Fluid Dampers. They offer enhanced performance with moderate power requirements.
Hybrid Control Devices: Integrate passive and active methods for superior performance, offering the benefits of various control strategies. Hybrid Mass Dampers (HMD) and Hybrid Base Isolation Systems exemplify this category, providing comprehensive vibration reduction but with increased complexity in design and implementation.
The choice of device significantly impacts structural resilience and the control strategy required for optimal performance.
Comprehensive Seismic Risk Mitigation Strategies
Vibration Control: AI dynamically adjusts damping, stiffness, and mass distribution to reduce structural movement during earthquakes, improving recovery and stability.
Design Optimization: AI algorithms, particularly genetic algorithms, enhance building design parameters for increased seismic resistance, leading to more efficient and adaptable designs.
Assessment and Monitoring: AI detects initial signs of damage using sensor data and predictive models, enabling proactive maintenance and rapid reconstruction to prevent structural collapse.
Seismic Retrofitting: AI identifies the most critical areas for retrofitting by analyzing past seismic data and structural features, optimizing efforts to strengthen existing buildings.
Optimize Materials: AI aids in designing and optimizing advanced materials with improved seismic resistance and damping properties, contributing to overall structural resilience.
Integrating these AI-driven strategies creates a holistic approach to building safety, ensuring enhanced durability and responsiveness to seismic threats.

Case Study: 10-Story Building Seismic Response
A 10-story high-rise building equipped with a Hybrid Mass Damper (HMD) was subjected to simulations using seismic excitations from the 1960 6.9 Mw El Centro earthquake and the more intense Southern Sumatra earthquake (8.4 Mw).
The comparative analysis involved the RBFNN-NTSMC controller, a Fuzzy Logic Controller (FLC), a Sliding Mode Controller (SMC), and an uncontrolled structure.
Key Findings:
- The RBFNN-NTSMC consistently demonstrated superior performance, achieving up to 63% reduction in building vibrations compared to the uncontrolled structure during the El Centro earthquake.
- The FLC and SMC achieved significantly lower reductions of 13% and 12%, respectively.
- During the more severe Southern Sumatra earthquake, RBFNN-NTSMC again showed marked outperformance with an IAE of 2.7501, far surpassing FLC (4.7045) and SMC (4.8265).
- This highlights the RBFNN-NTSMC's robust adaptive capabilities in handling complex and uncertain seismic conditions, ensuring enhanced structural stability and durability.
The study unequivocally validates the potential of AI-integrated control strategies to revolutionize seismic risk mitigation in modern buildings.
