The existing literature mainly focuses on the research of reinforced concrete (RC) beams under a single load such as blast or impact. In this paper, slab–rib–slab RC beam, new type structure widely used in bridge structures, was taken object. explicit dynamic analysis software LS-DYNA to numerically analyze response and failure behavior I-shaped combined impact loads. For reason, an effective n...

In Table S1, we provide information on the events we used for the receiver functions (RFs). The time-axis RFs are shown in Figure S1. With Figure S2 and Text S1, we derive the relationship between the change in estimated Moho depth and the change in the Vp/Vs ratio used in the reference model to convert Ps arrival time to depth. With Figure S3 and Text S2, we rationalize our observation of posi...

The instrumental polarization induced by a flat isotropic dielectric slab in microwave frequencies is discussed. We find that, in spite of its isotropic nature, such a dielectric can produce spurious polarization either by transmitting incoming anisotropic diffuse radiation or emitting when it is thermally inhomogeneous. We present evaluations of instrumental polarization generated by materials...

A tank experiment was carried out to investigate underwater sound propagation over an elastic bottom in flat and sloping configurations. The purpose of the experiment was to evaluate range-dependent propagation models with high-quality experimental data. The sea floor was modeled as an elastic medium by a polyvinyl chloride slab. The relatively high rigidity of the slab requires accounting for ...

This paper investigates the behavior of reinforced concrete continuous flat slabs after exposure to fire through experimental and theoretical analysis investigations were made. In the experimental part a series of tests carried out, to evaluate the effect of fire on the mechanical properties of concrete including a number of cubs and cylinders. Indirect fire exposure experiments are performed i...
