In this paper, the research methodology and findings related to the application of generative AI in building structure design are discussed in detail. Below are the main elements:

Research Methodology
The research methodology in this study focuses on using Generative AI models to autonomously and creatively generate new structural designs that ensure both safety and efficiency. The primary steps in this research include:
1. Data Collection and Preparation:
The authors trained their models using historical data and design examples from existing civil engineering projects. This data included technical specifications, load distribution, material types, and structural design details. The preparation process involved processing, classifying, and standardizing input data for the models to learn with greater precision and quality.
2. Selection and Implementation of Generative AI Models:
- Various generative AI models were used, including **Generative Adversarial Networks (GANs)** and **Variational Autoencoders (VAEs)**. These models can learn from complex data and produce new designs with different, optimized structures. By analyzing structural features, these models facilitated the generation of creative and optimized designs.
- During the implementation stage, the generative models were first trained on historical design data and then used to generate new design proposals.
3. Simulation and Evaluation of Designs:
- After generating structural designs, each design was tested using analytical models and structural simulators. These simulations assessed the strength, stability, and load distribution in the structures under various conditions such as earthquakes, lateral pressures, and wind forces.
- Models were evaluated based on multiple parameters, including maximum load capacity, deflection levels, and overall structural stability in different conditions.
4. Final Optimization of Designs:
- After initial evaluations, the algorithms optimized the designs by analyzing results and making modifications to dimensions, material distribution, and structural changes to achieve the best performance in terms of cost-effectiveness and durability.

Key Findings
The findings of this study reveal the high potential of generative AI in building structure design. Some of the key results are as follows:
1. Creative and Diverse Designs:
- The generative models produced innovative new designs that were not only structurally robust but also visually appealing. This demonstrated the potential of generative AI to bring more diversity to architectural design.
2. Improved Material Efficiency and Cost Reduction:
- The optimized designs created by AI led to reductions in material usage where structurally possible. This optimization resulted in lower overall construction costs and reduced natural resource consumption, which is important for environmental sustainability.
3. Enhanced Stability and Safety:
- Simulations showed that AI-generated structures had high resilience and safety under various environmental conditions, including earthquakes, wind forces, and lateral pressures. This indicated that the designs could be reliably applied to real-world settings.
4. Practical Applications and Increased Design Speed:
- The use of generative AI significantly increased the design process speed. Designs that could take days or weeks to create manually were automatically generated by the models within minutes, making it highly feasible to use these models in construction projects.
5. Potential for Large and Complex Projects:
- The study results suggest that generative AI can be applied in large-scale building projects with complex requirements. This would allow engineers and architects to more easily achieve high-efficiency, high-safety designs.

Overall, this paper highlights the transformative role of generative AI in structural design processes and suggests that using this technology could bring considerable improvements in the fields of civil engineering and architecture.
