Effects of plastic hinge properties in nonlinear analysis of reinforced concrete buildings

Comparison of Different Numerical Models of RC Elements for Predicting the Seismic Performance of Structures

“…Similar analysis, in terms of allowable stresses, as was common practice at the time, would lead to lateral resistance of 5 % of the frame weight (Carvalho et al 1999). In addition, all elements used in this study are only inelastic flexural failure mode, However, some past studies (Inel and Ozmen 2006;Jeong and Elnashai 2005) have reported that even for under-designed RC buildings, possessing inadequate transverse reinforcement, the shear demand is significantly lower than the shear capacity in both beams and columns and that no shear failure would occur. The shear force demand-capacity ratio is defined as…”

Seismic Performance Evaluation of Corroded Reinforced Concrete Structures by Using Default and User-Defined Plastic Hinge Properties

“…Hinge deformation shows strength degradation at point D where the structure might show sudden failure after this point. The failure of the structure can be defined by reaching the point D and E. In this study, the locations of the hinges of the selected frames were located according to the study done by Inel and Ozmen (Inel & Ozmen, 2006). The lengths of the plastic hinges were used to calculate the moment-rotation instead of momentcurvature given by Eq.…”

“…A total of 210 plastic hinge properties as a function of time (t: 0 (non-corroded), t: 25 years, t: 50 years) were defined to be used in the nonlinear static push-over analyses. In order to predict the moment-curvature relationships, a new developed software program SEMAp (Inel et al, 2009) was used. SEMAp (Inel et al, 2009) models the stress-strain relationships of steel and concrete by the user.…”

Progressive Collapse Analysis of RC Beams

“…The importance of stiffness and initial conditions for progressive failure was described [2]. The effects of plastic hinge properties in nonlinear analysis of reinforced concrete buildings was conferred by Mehmet Inel and Hayri Baytan Ozmen [3] which signifies the importance of modeling of hinges of building and point outs that hinges depends upon the type of element, material properties, longitudinal and transverse steel content, and the axial load level on the element. Ali Kheyroddin and Hosein Naderpour presented a paper on plastic hinge rotation capacity of reinforced concrete beams.…”
