There are only limited studies that directly correlate the increase in reinforced concrete (RC) panel structural capacities in resisting the blast loads with different RC panel structural properties in terms of blast loading characteristics, RC panel dimensions, steel reinforcement ratio and concrete material strength. In this paper, numerical analyses of dynamic response and damage of the one-...

in this paper, the non-linear dynamic response of novel steel sandwich panel with hollow i-core subjected to blast loading was studied. special emphasis is placed on the evaluation of midpoint displacements and energy dissipation of the models. several parameters such as boundary conditions, strain rate, mesh dependency and asymmetrical loading are considered in this study. the material and geo...

This paper presents the results of an experimental study on the low-velocity impact behavior of foam-core sandwich panels. Panels with PUR foam core and plain weave carbon fabric laminated face-sheets were subjected to low-velocity impact with hemispherical steel impactors of di erent diameters at various energy levels. Digital image correlation (DIC) technique (ARAMIS software) was used to mea...

We measured emissivity of sample presenting panel of ALMA antenna using Band-10 heterodyne SIS receiver as antenna switching balanced radiometer with 8 GHz instantaneous bandwidth. Receiver noise temperature measured with 80 K/300 K antenna loads was ≈560 K (DSB). Emissivity of the surface is detected at LO frequency about 840 GHz via the imbalance of the antenna switch due to extra reflection ...

This paper compares the measured lateral load behavior of a 0.4-scale “hybrid” precast concrete wall test specimen with the behavior of a second precast specimen designed to emulate monolithic cast-in-place reinforced concrete shear walls. Both walls have the same overall geometry and are constructed by placing rectangular wall panels across horizontal joints. The lateral resistance at the join...

This paper summarizes the experimental campaign carried out for development of new steel energy dissipative devices named Slit Dampers (SDs) designed earthquake protection structures. A total eighty-two shear plates with different openings and thicknesses are tested to investigate their behaviour under cyclic pseudo-static loading. Eight types studied, including SD narrow slits that divide plat...
