Abstract

A three-dimensional reinforced concrete frame structure under diluted debris flow impact was established using explicit dynamic analysis finite element software LS-DYNA. The dynamic damage distribution and stress redistribution process of the structure under the impact were calculated and analyzed. The results show that, under the impact of the diluted debris flow, the bottom columns of the frame fail to work, and the original path of the force transmission is changed. Under the continuous impact, the plastic damage in the structure accumulates with the stress concentration being deepened and the displacement of the structure increasing, making the ability of the structure to resist the impact decrease. The failure form of reinforced concrete frame under diluents debris flow impact is shear type.
