M. Del Carpio Ramos, G. Mosqueda and D.G. Lignos
MCEER-14-0003 | 10/30/2014 |376 pages | $35
Keywords: hybrid simulation, collapse assessment, steel moment frames, steel gravity frames, integration methods, substructuring technique
Abstract: This report presents two series of hybrid simulations examining the seismic response of a four-story steel moment frame building structure in an effort to realistically capture system-level behavior through collapse. In the first series of tests, a half-scale 1-bay by 1-story physical substructure of a special moment resisting frame is considered, while in the second series the physical substructure corresponds to the gravity framing system with a similar-sized specimen. An objective of this work is to demonstrate the efficacy of hybrid simulation with substructuring as a cost-effective alternative to earthquake simulators for large-scale system-level testing of structural frame subassemblies. More specifically, the performance of a newly-developed substructuring technique and integration method for hybrid simulation are evaluated since these can be greatly challenged when used with large and complex numerical substructures exhibiting large levels of nonlinear response. The test method was found to be reliable and to provide significant insight into experimental behavior of structural subassemblies under realistic seismic loading.

Air-Blast Effects on Civil Structures
J. Shin, A.S. Whittaker, A. Aref and D. Cormie
MCEER-14-0006 | 10/30/2014 |462 pages | $35
Keywords: detonations, computational fluid dynamics, fireball, design charts, reflection coefficients, scaled impulse, Mach reflection, concrete erosion strain
Abstract: The overarching goal of the research described in this report is to characterize the effects of detonations of high explosives, inside and in the immediate vicinity of the fireball. A computational fluid dynamics code is verified in 1D and validated in 2D for air blast calculations. The code is used to develop recommendations for modeling the effects of explosions in the near field, to generate new design charts appropriate for near-field air-blast calculations, and to update design charts for reflection coefficients for peak overpressure and for scaled impulse as a function of angle of incidence. Recommendations are provided for calculating values of erosion strain for finite element analysis of reinforced concrete components subjected to near-field air-blast loadings.
