Design of Reinforced Concrete Infilled Frames
Moretti, M. L.; Papatheocharis, T.; Perdikaris, P. C. (2014)The work presented in this paper aimed to evaluate the diagonal strut model for the design of reinforced concrete (RC) infilled frames, already broadly used as a design tool in the case of masonry infilled RC frames. The ... -
Experimental and numerical investigation of pipe T-junctions under strong cyclic loading
Papatheocharis, T.; Diamanti, K.; Varelis, G. E.; Perdikaris, P. C.; Karamanos, S. A. (2013)Tee pipe junctions are piping components widely used in industrial and pipeline applications. Their performance under severe loading conditions may be critical for the structural integrity of an industrial facility. When ... -
Gradient Elastodamage Model for Quasi-Brittle Materials with an Evolving Internal Length
Triantafyllou, A.; Perdikaris, P. C.; Giannakopoulos, A. E. (2015)The article presents a new approach based on a strain gradient damage constitutive law for modeling quasi-brittle materials such as concrete. The authors use a weak type nonlocal formulation of the problem, relying on ... -
A numerical model based on nonconvex-nonsmooth optimization for the simulation of bending tests on composite slabs with profiled steel sheeting
Tzaros, K. A.; Mistakidis, E. S.; Perdikaris, P. C. (2010)It is well known that the Calculation Of the ultimate strength of composite concrete slabs with profiled steel sheeting requires the determination of the longitudinal shear resistance which depends on the quality of the ... -
Numerical simulation of bending response of reinforced concrete and fibre-reinforced concrete beams
Georgiadi-Stefanidi, K. A.; Mistakidis, E. S.; Perdikaris, P. C. (2008)The aim of this work is to understand the behaviour of members made of fibre reinforced concrete (FRC). The members under study were fibre reinforced concrete beams with no conventional reinforcement, as well as fibre ... -
Structural integrity of steel hydrocarbon pipelines with local wall distortions
Pournara, A. E.; Karamanos, S. A.; Papatheocharis, T.; Perdikaris, P. C. (2014)Local distortions on pipeline wall in the form of dents or buckles may constitute a threat for the structural integrity of the steel pipeline. In the present paper, experimental research supported by numerical simulation ... -
Structural performance of steel pipe tee-junctions
Papatheocharis, T.; Diamanti, K.; Varelis, G. E.; Perdikaris, P. C.; Karamanos, S. A. (2014)The behavior of steel pipe junctions (Tees) subjected to strong loading in the presence of internal pressure is examined in the present study. The analysis is based on a set of monotonic and cyclic out-of plane bending ... -
Structural performance of TS590 high-strength steel welded tubular joints under extreme bending loading
Varelis, G. E.; Karamanos, S. A.; Papatheocharis, T.; Perdikaris, P. C. (2012)The present work examines the behavior of welded tubular connections made of high-strength steel and subjected to extreme loading conditions focusing on their low-cycle fatigue performance and highlighting the benefits of ...
