A large share of reinforced concrete (RC) framed buildings is provided with wide beams being a type of beam allowing greater freedom in the architectural arrangement of interiors, beyond further advantage due to fewer formworks needed during the construction. Nevertheless, little attention has been devoted to the seismic vulnerability of this kind of framed RC buildings as well as to the study ...

The addition of steel fibers into concrete improves the postcracking tensile strength of hardened concrete and hence significantly enhances the shear strength of reinforced concrete reinforced concrete beams. However, developing an accurate model for predicting the shear strength of steel fiber reinforced concrete (SFRC) beams is a challenging task as there are several parameters such as the co...

an energy based damage index based on a new nonlinear finite element (fe) approach applicable to rc structures subjected to cyclic, earthquake or monotonic loading is proposed. the proposed method is based on the evaluation of nonlinear local degradation of materials and taking into account of the pseudo-plastic hinge produced in the critical sections of the structure. a computer program is dev...

The problems of degradation concrete and reinforced constructions buildings long operation are formulated on the basis performed field researches its urgency is noted in work. authors analyzed a number works this problem. In particular, results technical diagnostics many structures, both newly built long-term operation, described. necessity periodic noted. Based these studies, main factors that...

The production process of fibre reinforced autoclaved aerated concrete results in a preferential orientation of the fibres. The fibre orientation largely influences the strength and the deformation behaviour of this building material, therefore information on the fibre orientation is highly desirable. Computed tomography measurements allow for the non destructive investigation of the material. ...

This paper investigates experimentally and analytically the torsion behavior of steel fibered high strength self compacting concrete beams reinforced by GFRP bars. Steel fibered high strength self compacting concrete (SFHSSCC) and GFRP bars became in the recent decades a very important materials in the structural engineering field. The use of GFRP bars to replace steel bars has emerged as one o...
