Unlike traditional AI models focused on prediction or classification, GenAI models, such as Generative Adversarial Networks (GANs), Variational Autoencoders (VAEs), Diffusion Models, and Large Language Models (LLMs), enable the generation of novel structural designs by learning complex patterns within design-performance data. This paper provides a comprehensive review of how GenAI can support tasks such as design generation, inverse design, data augmentation for surrogate modeling, and multi-objective trade-off exploration. It also examines key challenges, including constraint integration, model interpretability, and data scarcity. By evaluating recent applications and proposing hybrid frameworks that blend generative modeling with domain knowledge and optimization strategies, this study outlines a research roadmap for the responsible and effective use of GenAI in structural optimization. The findings emphasize the need for interdisciplinary collaboration to translate GenAI&rsquo;s creative potential into physically valid, structurally sound, and engineering-relevant solutions.</span></span></span></span></span> Generative Artificial Intelligence, Structural Optimization, Surrogate Modeling, Variational Autoencoder, Generative Adversarial Network, Diffusion Models, Large Language Models 317 334 http://ijoce.iust.ac.ir/browse.php?a_code=A-10-6463-30&slc_lang=en&sid=1 S.
