Analysis And Design Of RCC Structure With Light Weight Bricks Using ETABS

Abstract

This study aims to analyze and design a reinforced cement concrete (RCC) structure using light weight bricks and compare its performance with that of a conventional RCC structure using standard clay bricks, utilizing ETABS software as the primary tool for structural modeling and analysis. The use of lightweight bricks, such as autoclaved aerated concrete (AAC) blocks, has gained popularity in modern construction due to their reduced density, thermal insulation properties, and potential to decrease overall structural dead load. This research investigates the impact of incorporating lightweight bricks on the structural behavior of a multi-storied building, focusing on key parameters such as base shear, storey drift, displacement, and member forces. The results of the analysis reveal significant differences in structural performance between the two models. The use of light weight bricks leads to a notable reduction in base shear and member forces due to decreased dead load, resulting in improved seismic performance and potential cost savings in foundation design. Storey drift and displacement are also analyzed to ensure serviceability and safety under lateral loads. Overall, this study highlights the structural, economic, and sustainability benefits of using lightweight bricks in RCC construction. The findings provide valuable insights for engineers, architects, and developers, encouraging the adoption of light weight materials in structural design to enhance building performance while adhering to national code requirements. This study's contributes to the ongoing efforts to optimize construction practices and promote safer, more efficient, and environmentally conscious urban infrastructure in Bangladesh and similar regions worldwide.
