Performance and protection approach of single-layer reticulated dome subjected to blast loading
Abstract The elaborate finite element model of Kiewitt-8 single-layer reticulated dome with span of 40m subjected to eccentric blast loading was established and all the process from the detonation of the explosive charge to the demolition of reticulated dome structure was reproduced. The blast performance of reticulated dome was numerically studied and two approaches to improve the blast resistant capacity of reticulated dome were discussed. Response types of reticulated dome under eccentric blast loadings were defined. Partially reinforcement of reticulated dome is found to be an effective and economical way to improve its blast resistant capacity compared with fully reinforced reticulated dome. The pre-designed openings on the wall to release blast loading were studied, which provided some guidance on the blast resistant design of such structures.
Highlights Kiewitt-8 single-layer reticulated dome under blast load is numerically studied. Three response types are defined. Two blast protection approaches are discussed.
