“…Furthermore, the representation of smeared cracked materials as a continuum induces locked-in stress in elements close to the localisation zone and a too-stiff response of the structure is frequently found in such analyses (Ricardo et al, 2000). A similar overly-stiff response was also encountered in another NLFEA (Hon et al, 2001). …”

Punching failure is the common failure mode in concrete bridge deck slabs when these structural components are subjected to local patch loads, such as tyre loads. Past research has shown that reinforced concrete slabs in girderslab type bridges have a load-carrying capacity far greater than the ultimate static loads predicted by traditional design methods, because of the presence of compressive membrane action. However, due to the instability problems from punching failure, it is difficult to predict ultimate capacities accurately in numerical analyses. In order to overcome the instability problems, this paper establishes an efficient non-linear finite-element analysis using the commercial finite-element package Abaqus. In the non-linear finite-element analysis, stabilisation methods were adopted and failure criteria were established to predict the ultimate punching behaviour of deck slabs in composite steel-concrete bridges. The proposed non-linear finite-element analysis predictions showed a good correlation on punching capacities with experimental tests.

“…It can be seen that the load-deflection response in model S6 (simply supported model) predicted by NLFEA was relatively similar to that from the experimental tests. A similar overly stiff response has also been encountered in another NLFEA in research by Hon et al 23 Einsfeld et al 24 suggested that the reason for this was that a smeared cracked model suffers from stress-locking due to compatibility requirements in the finite element method. From Fig.…”

This paper summarises the results obtained from non-linear finite-element analysis (NLFEA) of a series of reinforced-concrete one-way slabs with various boundary conditions representative of a bridge deck slab strip in which compressive membrane action governs the structural behaviour. The application of NLFEA for the optimum analysis and design of in-plane restrained concrete slabs is explored. An accurate material model and various equation solution methods were assessed to find a suitable finite-element method for the analysis of concrete slabs in which arching action occurs. Finally, the results from the NLFEA are compared and validated with those from various experimental test data. Significantly, the numerical analysis was able to model the arching action that occurred as a result of external in-plane restraint at the supports and which enhanced the ultimate strength of the slab. The NLFEA gave excellent predictions for the ultimate load-carrying capacity and far more accurate predictions than those obtained using standard flexural or elastic theory.

“…Bei der für die Deckplatten von Straßenbrücken entwickelten Compressive Membran Action (CMA) wird von einem sich zwischen den Brückenhauptträgern in Querrichtung einstellenden Sprengwerk unter Radlasten ausgegangen (Bild ). Sowohl in der theoretischen Herleitung durch Rankin et al als auch in Versuchen von Taylor et al sowie Hon et al konnte ein signifikanter, der Sprengwerkwirkung zuzuschreibender Traglastanteil nachgewiesen werden. Bei der CMA wird davon ausgegangen, dass sich die Traglast der Platte als Summe aus Biege‐ und Sprengwerktragfähigkeit ergibt.…”

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.
