Bompa DV, Elghazouli AY, 2017, Punching shear strength of RC flat slabs provided with shear-heads at interior connections to steel columns, Pages: 823-831
© Springer International Publishing AG 2018. This paper investigates the structural performance of cruciform shear-head systems fully integrated in RC flat slabs at interior connections to steel columns. The test results from a series of six large scale members of which two were provided with headed shear studs, offer a direct evaluation of the full load-deformation behaviour of the specimens as well as the ultimate punching shear strength attained prior to failure at the critical slab perimeter outside the shear-head region. Particular focus is given to the influence of the shear-head and headed shear stud reinforcement to the member kinematics and failure characteristics. The experimental findings coupled with shear field analyses enable the development of analytical models that depict the rotational response and flexural strength as a function of the shear-head characteristics, and support the definition of a shear-head dependent control perimeter required for punching shear strength assessments. Additionally, analytical design expressions that adopt the fundamentals of Model Code 2010, which account for the characteristics of the shear-head system, are proposed and their results capture in a more realistic manner the shear-head influence on the punching shear strength of RC flat slabs in such hybrid configurations in comparison with strength predictions from current conventional RC design methods.

Bompa DV, Elghazouli AY, 2017, Bond-slip response of deformed bars in rubberised concrete, Construction and Building Materials, Vol: 154, Pages: 884-898, ISSN: 0950-0618
This paper is concerned with examining the complete bond-slip behaviour between deformed reinforcement bars and concrete incorporating rubber particles from recycled tyres as a partial replacement for mineral aggregates. An experimental study consisting of fifty-four pull-out tests on cylindrical rubberised and normal concrete specimens, in conjunction with two reinforcement sizes with short embedment lengths, is described. In addition to a detailed assessment of the full bond-slip relationship, the test results offer a direct interpretation of bond behaviour under practical levels of confinement and its influence on the failure modes. Particular emphasis is given to the characteristic bond behaviour of rubberised concrete in terms of maximum bond strength and splitting strength as well bond stiffness and slip parameters. The detailed test measurements and observations provided in this study enable the definition of key bond parameters depicting the interfacial behaviour between rubberised concrete and deformed bars. The findings also permit the development of modified approaches for reliable representation of the failure modes and bond capacities for the concrete materials considered in this investigation.

©Springer International Publishing AG 2018. This paper examines the inelastic behaviour of dissipative zones in structural members incorporating high deformability concrete materials in which mineral aggregates are partly replaced by rubber particles. An experimental study on three large-scale circular reinforced concrete column specimens, subjected to lateral cyclic displacements and co-existing axial loads, is described. The testing arrangement, specimen details, and main observations, are presented and discussed. The test results enable a direct assessment of the strength and ductility characteristics of the specimens. In particular, the study permits an evaluation of the comparative performance of structural members with and without rubber replacement, as well as the influence of external confinement. The results show that, in comparison with conventional reinforced concrete members, structural elements incorporating a significant proportion of aggregate replacement by rubber particles can offer a good balance between bending capacity and ductility, particularly for modest levels of co-existing axial loads. For column members required to sustain substantial gravity loads, favourable performance can be achieved in rubberised concrete members by means of strength enhancement through external confinement such as fibre reinforced sheets. Based on the experimental findings, the main material and response parameters are discussed and their influence on the overall structural behaviour are highlighted.

Moharram M, Bompa D, Elghazouli A, 2017, Inelastic assessment of hybrid RC beams to steel column configurations using structural steel shear-keys, Pages: 1336-1343
© Springer International Publishing AG 2018. This study describes experimental and numerical investigations into the inelastic behaviour of hybrid reinforced concrete (RC) beams. The RC beams are connected to steel columns by means of fully embedded structural steel profiles. Observations from a series of ten full-scale hybrid Steel/RC specimens are presented. Nonlinear finite element procedures are carried out and validated against the experimental results from the hybrid tests in this paper. The ability of the numerical models to provide faithful prediction, using a consistent set of material modelling parameters, provides a high level of confidence in the reliability of the simulation techniques. Finally, some simplified analytical representations of the failure surfaces are proposed in which potential failure conditions are predicted and classified in reference to a suggested hybrid Mode Index.
