摘要

The waste from agricultural products is a significant environmental issue that has caused numerous problems in many countries worldwide. Researchers have suggested using them in concrete as an efficient and economical solution. However, they are usually used in their form in concrete, which only consumes a small volume and may not significantly contribute to environmental improvement. On the other hand, the use of Ultra High Performance Concrete (UHPC) is expanding in the world. However, comprehensive studies evaluating its performance in structures have not been widely conducted. Therefore, in this paper, an innovative idea of using sugarcane bagasse as a permanent filler or framework, along with the use of UHPC was presented and investigated numerically and parametrically. Through this technique, a large amount of bagasse can be used, which will significantly benefit the environment and also reduce the costs of recycling agricultural products. The evaluation of the results shows that the use of UHPC instead of ordinary concrete in beams has a significant effect on reducing the displacement and drift ratio. Also, the UHPC use in tall buildings reduces the volume of concrete, which results in optimal performance of the structure. Finally, the results show that the largest amount of bagasse can be used in slabs in comparison to beams and columns.
