experimental data、experimental data and BPNN data

This dataset supports the study on the axial compressive behavior of recycled aggregate concrete-filled circular steel tube (RACFST) short columns incorporating varying steel fiber contents. It comprises experimental measurements, finite element (FE) simulation results, and back-propagation neural network (BPNN) modeling data. The data are provided to enable full reproducibility of the reported results and to facilitate further analysis by other researchers.本数据集可支撑针对掺加不同钢纤维掺量的圆钢管再生骨料混凝土（Recycled Aggregate Concrete-filled Circular Steel Tube, RACFST）短柱轴心受压性能的研究。数据集包含试验实测数据、有限元（Finite Element, FE）模拟结果以及反向传播神经网络（Back-propagation Neural Network, BPNN）建模数据。提供本数据集旨在实现已报道研究结果的完全可复现，并为其他研究人员开展后续分析提供便利。
