Development of a scalable, low-cost conductive concrete with a long lifetime has the potential to evolve into a new solution for the next generation of floor heating systems. This work systematically investigates the performance of nano carbon black (NCB) cement composite as a viable candidate for floor heating. To this end, its conductivity and jo...
This study investigates the behavior and the load-bearing mechanism of a typical flat slab with rectangular panels in several scenarios including the removal of a corner, penultimate, and internal columns. The scenarios are rather similar to those used in the conventional evaluation of the progressive collapse potential; however, application of the...
Compressive arch action (CAA) is a desired load-bearing mechanism to mitigate the progressive collapse risk of commonly designed reinforced concrete (RC) frames. Thus, there have been number of studies concentrated on the behavior of in-plane beam-column sub-assemblages under a single column removal scenario. However, the effect of possible multico...
Recycled aggregates were widely used in the concrete industry as a replacement of natural aggregates in the last two decades. In this study, the resistance of concrete mixtures having various levels of recycled aggregate as a replacement of natural coarse aggregate to the attack of magnesium and sodium sulfates was investigated. Five mixtures made...
Analytical equations found in the literature to give the ultimate load of folding, punching shear and local slab collapse mechanisms have been generally derived assuming a uniform load on all flat slab panels. Regarding that these formulas are not able to consider the impact of unbalanced bending moment due to partial loading, they cannot be applie...
As a well-known technique, alternate path method (APM) has been widely used to evaluate progressive collapse potential of structures. This method investigates the capability of structures to redistribute loads carried by a removed element in the remainder. However, in most cases the initiating event is so intensive that it destroys more than one lo...
Loss of an external facade column is among the most probable scenarios in evaluating the vulnerability of a structural system to progressive collapse. In the case that the column loss causes adjoining panels to fall down in a two-way slab reinforced concrete structure, the capability of the lower floor to prevent formation of any collapse mechanism...
SUMMARY A large part of common reinforced concrete (RC) structures are designed as intermediate moment resisting frames. However, current progressive collapse studies have not paid much attention to these frames. In this study, based on the acceptance criteria of the UFC 4-023-03 document, the influence of some external and corner column removal ca...
