Curvature Ductility of High Strength Concrete Beams
Journal of Materials and Engineering Structures, 2017 The ductility of reinforced concrete beams is very important, because it is the property that allows structures to dissipate energy under seismic loading, consequently, the brittle fractures of reinforced concrete structures can avoided. In the modern construction of reinforced concrete structures, the high-strength concrete (HSC) is widely used ...

Ductility of Partially Prestressed Concrete Beam
Key Engineering Materials, 2006Ductility of partially prestressed concrete beams was numerically analyzed. For a given value of reinforcement index, corresponding curvature ductility factors of an unbonded prestressed concrete beam as well as a bonded prestressed concrete beam are analyzed and compared. It is generally observed that, when reinforcement index is between 0.20 and 0.30,

Variation of Ductility Capacity of Steel Beam‐Columns
Journal of Structural Engineering, 1994This paper presents an investigation on the variation of ductility capacity of steel beam-columns. First, experimental data obtained from previous tests are surveyed, and their ductility ratios are examined. It is found that experimental ductility ratios scatter over a wide range with their coefficients of variation ranging from 0.4 to 0.9.

Sectional Ductility of Wide Beams
5th International Students Science Congress, 2021Wide beam structures are categorized as Limited Ductility Class in Turkey and elsewhere and considered not fit for construction in areas of high seismicity. One of the main reasons that wide beam structures are considered to possess limited ductility is the perceived low local ductility of the wide beams, due to the high reinforcement ratios.

Ductile Design of Glued-Laminated Timber Beams
Practice Periodical on Structural Design and Construction, 2009Ductility is a fundamental component in the design of robust structures. For timber structures, the unfavorable material characteristics pose particular problems to its realization. Two approaches for improving the post-elastic behavior of glued-laminated timber beams have been investigated by testing and numerical analysis.

Impact of finite beams of ductile metal
Journal of the Mechanics and Physics of Solids, 1954Abstract An analysis is here presented of the large plastic deformations of a beam under impact such as that due to a blow of a massive hammer, in which one cross-section is suddenly forced to move with a given velocity. The analysis treats both the case in which the velocity of the struck section is maintained constant until the total permanent ...
