Abstract

In response to the low assembly level of the existing steel structure flexible shelter system, the use of welding as the connection method for supporting components, and the unreasonable arrangement of energy dissipation buffer layers, resulting in slow installation speed of the steel structure shelter, difficulty in replacing local components after being damaged by falling rocks, and low energy consumption levels, this paper proposes a steel structure modular energy dissipation shelter system based on a cable supported flexible buffer layer, This system replaces the flexible support in the cable supported flexible buffer layer with rigid support. A dynamic nonlinear numerical model of the shed tunnel was established, and the influence of different support conditions on the impact dynamic response of the shed tunnel was analyzed. The influence of impact velocity on the shed tunnel was studied. The results indicate that rigid support is more conducive to the stability of cable supported columns; Compared to the existing flexible shed tunnel with a protective energy level of 250KJ, the modular energy dissipation shed tunnel system of this steel structure can achieve protection of 2000KJ energy level, and the protective energy level of the system has been increased by 700%; The impact speed has a small impact on the buffering distance, but a significant impact on the impact force and internal force of the system support components.
