“…The first equation has a root u = 0.31, but in the second equation, u is obtained as a function of R . Based on these results, Rankin and Long obtained a polynomial relationship between M r and R according to Eq. :

\begin{matrix} left \\ (i) R > 0.26 \Rightarrow M_{r} = \frac{0.3615}{R} \\ (ii) 0 < R < 0.26 \Rightarrow M_{r} = 4.3 - 16.1 \\ \sqrt{3.3 \cdot 10^{- 4} + 0.1243 R} \end{matrix}

“…Hence, the present study introduces a theoretical approach for estimating the arching capacity of RC beams under large deformations caused by progressive collapse. The present method is developed based on the procedure introduced previously by Rankin and Long for one‐way slabs. The approach introduced here estimates compressive arch capacity based on the geometrical and structural details of beams and without any need to perform a repetitive procedure.…”

Compressive arch action is one of the main resistance mechanisms against progressive collapse in reinforced concrete (RC) buildings. Hence, many studies have investigated the development of arching action in RC beams and frames but less attention has been paid to calculating the corresponding enhancement in structural capacity. In the present study, a theoretical method is introduced in order to calculate the arching capacity of RC beams and also to obtain a quantitative assessment regarding structural robustness against progressive collapse. The proposed method is validated using the experiments in the literature. The evaluation indicates that the procedure introduced here could establish a reliable foundation for estimating the arching capacity of beams and also structural robustness.

“…McDowell et al [9], Park [10][11][12] and Hewitt and Batchelor [13] proposed methods to estimate the capacity enhancement in restrained concrete members. Several research studies examined theoretical models to predict the capacity and behavior of restrained concrete members [14][15][16][17][18]. Most of the studies concluded that the failure mode of the restrained member is punching shear but the mode is highly dependent on the degree of restraint.…”

Vault bearing effect of continuous iron concrete slabsrescue of functioning monuments? Historic iron concrete slabs often have impressive slenderness. The sustainable use of listed buildings in a partially modified function requires proof of structural security. The existing constructions can often not be proven according to the usual, currently applicable design methods. This is often contrasted with the observation of a damageless use so far. Parallel to load tests, the approach of the vault bearing effect of slabs with horizontal deformation restriction appears promising as a monument-compatible and economical solution for minimizing retrofitting measures. Based on material and geometrical nonlinear calculations, the principal effects of slender, one-direction spanned slabs were investigated. Based on the theory of Compressive Membrane Action, a simplified calculation model for qualitative parameter studies was developed. The verification method with the model within the scope of the valid standards shows partially significant load reserves. The application of the model requires an in-depth material exploration in the existing structure.
