Other AbstractThe energy dissipator between roof and beam of rock sheds is beneficial for significantly improve the impact resistance of rock shed hold engineering.In this study,a new metal energy dissipator with corrugated structure was proposed to reduce the maximum yield load,stabilize the buckling stage and increase the energy consumption,eventually improving the impact resistance ability of shed hold engineering.The compression tests were conducted to analyze the mechanical behavior of the corrugated tubular energy dissipators with different parameters, and the dynamic finite element method was used to simulate the compression process and compared with the physical model test.Next,by performing the impact tests on the shed hole with different energy dissipator the mechanism of energy disspation device was revealed through the comparatively anylsis of roof's deflection,the pressure to foundation and energy absorption.The results showed that,compared with the cylindrical damper,using corrugated cylinder metal energy dissipator reduces the initial yield load to about 1/3,and it was more easily to achieve the form of stable axisymmetric buckling process.Numerical simulation showed that when the rock shed subjected to impact loading,the maximum deflection of roof could be reduced by about 47%.At the same time,both the pressure of the rock shed to the foundation and the vibration generated between part of rock shed structure could be reduced to some extent with the change of the impact energy.The magnitude of the energy consumption of corrugate cylinder metal energy dissipator was much higher than that of the commonly used cylinder energy dissipator.Therefore,intalling the corrugated cylinder metal energy dissipator is beneficial for improving the anti-impact ability of rock shed hold engineering.
