In the modelling of reinforced concrete (RC) buildings, rigid diaphragm hypothesis to represent in-plane behavior floors was and still is very commonly adopted because its simplicity computational cheapness. However, since excessive floor deformability can cause a different redistribution lateral forces on vertical resisting elements, it may be necessary consider deformability. This paper inves...

2014 The density of states of quasiparticles in an anisotropic flat slab or half-space is calculated in the effective mass tensor approximation. The results obtained are used to find the surface contribution to the density of states which is proportional to the surface-to-volume ratio. Under certain conditions discussed in the paper, the surface contribution found remains valid for an assembly ...

An unsaturated polyester resin (UPR) mortar was applied to repair the damage tension zone's one-way reinforced concrete (RC) slabs. The load carrying capacity of patched RC slab is interest justify effectiveness repair. Yield Line Theory (YLT) may be used estimate slabs under concentrated load. results YLT are compared with experimental evaluate validity method. confirm that patching alters yie...

The equivalent viscous damping (EVD) ratio is a crucial parameter in the application of the displacement based design (DBD) method. Previous works have correlated the EVD ratio as a function of the displacement ductility level based on the hysteretic response of reinforced concrete members subjected to blast loads. Furthermore, the displacement response factor (DRF) for blast loads was proved t...
