Punching failure and compressive membrane action in reinforced concrete slabs
This study of punching failure and compressive membrane action in reinforced concrete slabs provides a basis for the development of a more realistic design approach for continuous slabs subjected to concentrated loadings.The results of an extensive series of tests on one quarter scale models of the …

The Study of Glyceraldehyde -3 -Phosphate Dehydrogenase (Gapdh) Function Targeted by Estrogen and Progesterone in the Central Nervous System: Physiological Implications
… results and describes a proposed model for the membrane action of estradiol on GAPDH in the hippocampus that reflects recent interesting reports from other laboratories as well as my own contributions to these novel functions of GAPDH.

The real strength of laterally restrained reinforced concrete slabs
It is widely recognised that Compressive Membrane Action (CMA ) is the reason for the strength enhancement exhibited by laterally restrained slab system . This strength enhancement is in excess of that estimated by standard flexural and shear design methods.<br/><br/>Although of the fact that the …

An analytical field and model study of M-beam bridge decks
… the standard 160 mm M—beam deck slab under the action of the abnormal vehicle wheel load was investigated in a series of tests on a - scale model. The main variables were the percentage of steel reinforcement and the spacing of the beams. Twenty panels were tested and they all failed in …

Effect of Lateral Stiffness on Bridge Deck Performance
… steel reinforcement but to an implicit arching membrane stress set-up as an effect of the lateral restraint surrounding the deck slab known as Compressive Membrane Action (CMA). It has been proved through research that most design codes underestimate the strength of laterally restrained slabs. …

Partially prestressed concrete internal square panel
… line theory and the increase was attributed to membrane action. The experimental values of tendon stress at ultimate load and of punching shear were compared with those obtained by various design methods.

Thin-shell Concrete Floors for Sustainable Buildings
… dominant structural behaviour from bending to membrane action increases efficiency, enabling significant embodied carbon reductions. A system is proposed featuring pre-cast textile reinforced concrete shells of uniform thickness and shallow depth, supported at columns, with a network of …

Self-duality for SU([infinity]) gauge theories and extended objects
… (p-branes). An approach to self-duality for membranes is developed using the correspondence between the large N limit of SU(N) gauge theories and the membrane theory. This correspondence is established via the use of the coadjoint orbit method. It is shown that classical gauge field theories …

Blast Resilience of Glazed Façades: Towards a New Understanding of the Post-Fracture Behaviour of Laminated Glass
… moment capacity, arising from the combined action of the glass fragments in compression and the interlayer in tension, which is considered negligible under low strain-rates. The post-fracture resistance is significantly improved by the introduction of in-plane restraint, due to the membrane …

Investigation into the toxicity and membrane interactive properties of a range of cationic photosensitisers with potential application to Photoantimicrobial Chemotherapy
… suggesting an ability to interact with lipid or membranes. Studies on the potential of these PhBPs for lipid / membrane action showed that all of these dyes possessed inherent abilities for haemolytic activity (ranging between 6% and 19%) and bacteriolytic activity when directed against E. co/i …

Πειραματική διερεύνηση σταδιακής κατάρρευσης κτιρίων οπλισμένου σκυροδέματος λόγω τυχηματικών δράσεων
Ακραίες δράσεις όπως οι εκρήξεις ή η πρόσκρουση οχημάτων σε κατασκευές μολονότι παρουσιάζουν μικρή πιθανότητα εμφάνισης, εν τούτοις οι συνέπειες για τις κατασκευές μπορεί να είναι τέτοιες που να οδηγήσουν σε κατάρρευση, καθώς η τοπική βλάβη σε ένα μέλος ενδέχεται να εξαπλωθεί διαδοχικά και στα …
