| Summary: | A new concept of flexible rock-shed is proposed in this paper. The flexible
rock-shed is made of flexible nets held up by a specially designed, steel
vaulted structure. A 1:1 prototype is manufactured and tested for
functional evaluation with an impact experiment. It is shown that the structure
can stand for an impact energy of about 250 kJ without observable rupture of
the flexible nets or cables and can be put into service again with some
maintenances on the steel vaulted structure. Experimental data such as local
strains, peak loads and impact times are recorded by dynamic strain gauges,
load cells and a high-speed camera for structural analysis and some
complementary suggestions of improving and designing are offered with respect
to the joints and components. Finally, the advantages and limitations of the
flexible rock-shed are outlined and the limits of the present experimental
investigation and the future research for the flexible rock-shed are
proposed. |
