Abstract: This review paper presents a comprehensive analysis of Reinforced Concrete (RCC) and Composite buildings, evaluating their performance, design, seismic behavior, cost-efficiency, and sustainability. It outlines their distinct characteristics and structural suitability. The review examines construction methods and technology, highlighting advantages and limitations. Environmental impact, embodied energy, and recyclability are assessed for sustainable construction practices. Economic considerations encompass initial costs, maintenance, and life-cycle analysis. Seismic performance and design strategies are analyzed for resilience in seismic-prone regions. This review paper provides an in-depth analysis of various research papers associated with the topic of RCC and Composite buildings comparison and its various advancements. A thorough literature review has conducted along with analysis of previous works in this field, our study has identified conclusive outcomes from the gap of the study that form the basis of our research objectives that will offer technical insights and propose recommendations for technical research work in this field.
