“…Nevertheless, very limited experimental or analytical data are available for the case that only some panels of the two-way slab floor are excessively loaded with the load on others kept constant. In a full-scale test in Copenhagen, part of a reinforced concrete (RC) deck was investigated and an increasing uniformly distributed load was applied to an edge slab with horizontal restraint along only three sides until a relatively large deflection was reached (Christiansen and Frederiksen, 1983). Even this case yielded a crack pattern consistent with the theoretical model.…”

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 plays an important role in averting progressive collapse. This paper introduces relevant beam-slab collapse modes of the impacted storey, as well as developing a formula for the ultimate load of each mechanism using yield line analysis. The formulation includes beam and slab main properties and could be used as a way to roughly estimate the extent of collapsed area in lower storeys. A study is also performed to determine the influence of some parameters on the predicted ultimate load. It is concluded that the ratio of beam to slab flexural strength and existing dead and live loads on panels in the vicinity of impacted panels could change the yield line pattern and subsequently control the prevailing collapse mode.

“…The prevention of this strain by end restraint as shown in Figure-1 which produces a compressive membrane forces in the member enhances the capacity of that member, which leads to empirical method of design [29,30]. It has also being fund out that, members with lower span to depth ratios have higher arching action behaviour due to their higher compressive strength and accompanying crushing strain [31][32][33][34][35][36][37][38]. The use of minimum steel percentage in restrained slabs reduces maintenance cost, increase durability and enhanced Punching shear capacity [39].…”

Transverse Slab Reinforcement Design of Concrete Bridge Deck: A Review

et al. 2018

This paper reviews the current design practices of transverse slab reinforcement design in concrete bridge deck, which consist of concrete deck slab on wide concrete T-beams. The conventional bridge design method results in the provision of excessive transverse steel reinforcement in the concrete bridge deck slab due to the fact that, the slab is assumed to bear the applied vehicular loadings alone without considering the contribution of the wide T-beam flanges. Thus, the design which is based on bending and failure proved to be too conservative. Through critical review, issues regarding some design approaches were discussed. It has been found that, designing the deck slab in transverse direction would enable the vehicle wheel loads to be supported by the wide T-beam flanges and performance enhancement can be achieved by compressive membrane action resulted from the natural stiffness of the wide girder flanges. The presence of this membrane forces provides a punching shear capacity, which is far beyond the flexural design capacity for the new bridge deck system. This capacity would result in substantial reduction of the transverse reinforcement within the slab.
