Available in PDF, EPUB and Kindle. Book excerpt: "This thesis investigates the post-punching behaviour of reinforced concrete slab-column connections. Seven interior slab-column connections were tested to study the effects of slab thickness, the length of structural integrity reinforcing bars, the distribution of structural integrity reinforcement in slabs with rectangular columns and the placement of structural integrity reinforcement in slabs with drop panels. Results from this test series and from tests by other researchers were compared with predictions using the CSA A23.3-04 design equations for both punching shear and post-punching resistance. The test results demonstrated that the provision of structural integrity reinforcement in accordance with the requirements of CSA A23.3-04 resulted in significant post-punching resistance and the design equations provide a reasonable estimate of this resistance. In addition, an analytical model for predicting the post-punching shear response of slab-column connections is presented which accounts for the individual contributions of each layer of top reinforcement and each layer of the structural integrity reinforcement. The contribution of each layer of top and integrity reinforcement is governed by three different failure modes, including rupture of the bars, concrete breakout of the bars and pullout of the bars. The predictions are compared with experimental results and the results obtained by the CSA A23.3 Standard design method. There was a good agreement between the predicted results and the experimental results." --

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The provision of structural integrity reinforcement provides a secondary defence mechanism after punching shear failure in two-way slab systems and prevents progressive collapse. The effectiveness of structural integrity reinforcement in a slab system, designed in accordance with the 2014 CSA A23.3 standard, was investigated in this experimental program. A full-scale slab structure, consisting of two continuous 3.0 × 3.0 m bays and supported by six exterior columns, was subjected to extreme overloading, causing punching shear failure in all of the slab-column connections. The sequence of punching shear failures was monitored and the post- punching shear behaviour due to the presence of structural integrity reinforcement was examined. In order to estimate the response of individual columns, the load distribution ratio at the columns was calculated using the SAP2000 structural analysis software, with the stiffness of slab-column connections failing in punching shear being adjusted using the analytical model developed by Habibi et al. (2014). The responses of the individual slab-column connections suggested that the code provides conservative predictions of the punching shear resistance due to shear and moment transfer. The torsional cracking due to the moments being transferred at the edge and corner columns reduced the concrete breakout strength after punching shear and limited the performance of the structural integrity reinforcing bars.The assessment of the overall performance indicated that the slab structure was able to provide overall post-punching shear resistance which was significantly higher than the design service load." --

This book was released on 2017 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: fib Bulletin 81 reports the latest information available to researchers and practitioners on the analysis, design and experimental evidence of punching shear of structural concrete slabs. It follows previous efforts by the International Federation for Structural Concrete (fib) and its predecessor the Euro-International Committee for Concrete (CEB), through CEB Bulletin 168, Punching Shear in Reinforced Concrete (1985) and fibBulletin 12, Punching of structural concrete slabs (2001), and an international symposium sponsored by the punching shear subcommittee of ACI Committee 445 (Shear and Torsion) and held in Kansas City, Mo., USA, in 2005. This bulletin contains 18 papers that were presented in three sessions as part of an international symposium held in Philadelphia, Pa., USA, on October 25, 2016. The symposium was co-organized by the punching shear sub-committee of ACI 445 and by fib Working Party 2.2.3 (Punching and Shear in Slabs) with the objectives of not only disseminating information on this important design subject but also promoting harmonization among the various design theories and treatment of key aspects of punching shear design. The papers are organized in the same order they were presented in the symposium. The symposium honored Professor Emeritus Neil M. Hawkins (University of Illinois at Urbana-Champaign, USA), whose contributions through the years in the field of punching shear of structural concrete slabs have been paramount. The papers cover key aspects related to punching shear of structural concrete slabs under different loading conditions, the study of size effect on punching capacity of slabs, the effect of slab reinforcement ratio on the response and failure mode of slabs, without and with shear reinforcement, and its implications for the design and formulation in codes of practice, an examination of different analytical tools to predict the punching shear response of slabs, the study of the post-punching response of concrete slabs, the evaluation of design provisions in modern codes based on recent experimental evidence and new punching shear theories, and an overview of the combined efforts undertaken jointly by ACI 445 and fib WP 2.2.3 to generate test result databanks for the evaluation and calibration of punching shear design recommendations in North American and international codes of practice.

Book Synopsis Towards a rational understanding of shear in beams and slabs by : fib Fédération internationale du béton
Download or read book Towards a rational understanding of shear in beams and slabs written by fib Fédération internationale du béton and published by FIB - Féd. Int. du Béton. This book was released on 2018-05-01 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reliable performance of beams and slabs in shear is essential for the safety and also for the serviceability of reinforced concrete structures. A possible failure in shear is usually a brittle failure, which underlines the importance of the correct specification of the load carrying capacity in shear. The knowledge of performance in shear is steadily developing and it is now obvious that older structures were not always designed in accordance with contemporary requirements. The increasing load – mainly on bridges – requires the assessment of existing structures, often followed by their strengthening. An appropriate understanding of actual performance of concrete structures in shear is therefore of primary interest. The workshop which was held in Zürich in 2016 brought together a significant number of outstanding specialists working in the field of shear design, who had a chance to exchange their opinions and proposals for improving the current knowledge of shear behaviour in beams and slabs. The specialists came from different parts of the world, which made the workshop general and representative. The workshop was organised by fib Working Party 2.2.1 “Shear in Beams” (convened by O. Bayrak), which is a part of fib Commission 2 "Analysis and Design". Individual contributions mainly address shear in beams with low transversal reinforcement. It is crucial because many existing structures lack such reinforcement. Different theories, e.g. Critical Shear Crack Theory (CSCT), Modified Compression Field Theory (MCFT), Multi-Action Shear Model (MASM), etc. were presented and compared with procedures used in selected national codes or in the fib Model Code 2010. The models for shear design were often based to a great extent on empirical experience. The refined presented models tend to take into account the physical mechanisms in structures more effectively. A brittle behaviour in shear requires not only to check the equilibrium and failure load, but also to follow the progress of failure, including the crack development and propagation, stress redistribution, etc. The significance of the size effect – which causes the nominal strength of a large structure to be smaller than that of a small structure – was pointed out. Nowadays, the fibre reinforcement is used more than before since it allows significant labour costs savings in the construction industry. The contribution of fibres is suitable for shear transfer. It is very convenient that not only ordinary fibre reinforced elements were addressed but also the UHPFRC beams. The production of this new material is indeed growing, while the development of design recommendations has not been sufficiently fast. Fatigue resistance of structures with low shear reinforcement is also an important issue, which was also addressed in this bulletin. It cannot be neglected in prestressed bridges, which are exposed to dynamic loads. A comprehensive understanding of the shear behaviour is necessary. Although many laboratory experiments are carried out, they are suitable only to a limited extent. New testing methods are being developed and show promising results, e.g. digital image correlation. An actual structure performance should rather be tested on a large scale, ideally on real structures under realistic loading conditions.ii The papers presented in the bulletin are a basis for the discussion in view of the development of updated design rules for the new fib Model Code (MC2020), which is currently under preparation. fib Bulletins like this one, dealing with shear, help to transfer knowledge from research to design practice. The authors are convinced that it will lead to better new structures design of as well as to savings and to a safety increase in older existing structures, whose future is often decided now.
