Composite beams with welded stud shear connectors pose challenges in terms of disassembly and reuse, which impacts their sustainability. By bolting steel to concrete, we can aquire a more sustainable alternative, facilitating easier disassembly and reuse. Engineers value concrete-steel bolted shear connections for their fatigue resistance, secure connections, and ease of disassembly. These factors make them suitable for various applications. Proper design is crucial for these connections to ensure effective shear force transfer and durability. This project provides valuable insights into analyzing bolted concrete-steel connections. It helps utilizing advanced modeling techniques in ABAQUS to simulate their behavior under different loading conditions. By addressing the benefits and challenges of experimental and numerical methods, this project enhances our understanding of composite connections. It enables improved construction practices. To ensure model’s accuracy, we compared the results with the experimental data, for steel concrete bolts. The project specifically helps you to simulate the bahavior of steel concrete composite beams in the following paper. “A study on structural performance of deconstructable bolted shear connectors in composite beams”
