Research has been undertaken to develop damage curves for reinforced concrete column members. A broad range of parameters that influence the damageability of reinforced concrete columns were investigated using finite element program ANSYS v6.1. Damage curves expressed in terms of interstory drift ratio were developed for three levels of ductility from the results of numerical investigations. The levels of ductility were determined based on the axial load level and the transverse reinforcement ratio. These curves are invaluable for estimating damage level of reinforced concrete frame buildings, which are predominantly used throughout the world, especially in developing countries. In addition, many procedures used to evaluate building performance employ acceptance criteria for the components comprising the whole structure so these curves are also recommended for use in the acceptability of reinforced concrete columns of frame structures.

Optimal design of planar and space structures with genetic algorithms Erbatur, F; Hasançebi, Oğuzhan; Tutuncu, I; Kilic, H (Elsevier BV, 2000-03-01) One of the most important practical considerations in the optimization of steel structures is that structural members are generally to be selected from available steel profiles. Furthermore, the solutions produced according to the national specifications are undoubtedly valuable from the point of view of applicability in real-life practice. This paper reports the development of a computer-based systematic approach for discrete optimal design of planar and space structures composed of one-dimensional element...
Optimum design of high-rise steel buildings using an evolution strategy integrated parallel algorithm Hasançebi, Oğuzhan; Kurç, Özgür (Elsevier BV, 2011-11-01) The present study addresses a parallel solution algorithm for optimum design of large steel space frame structures, in particular high-rise steel buildings. The algorithm implements a novel discrete evolution strategy optimization method to effectively size these systems for minimum weight according to the provisions of ASD-AISC specification and various practical aspects of design process. The multitasking environment in the algorithm rests on a master-slave model based parallelization of the optimization ...
OPTIMIZATION AND SENSITIVITY OF PRESTRESSED CONCRETE BEAMS ERBATUR, F; ALZAID, R; DAHMAN, NA (Elsevier BV, 1992-12-03) This paper is concerned with the optimum design of prestressed concrete beams. Both minimum weight and minimum cost optimization formulations are given for simply supported beams having three different sections. Sensitivity of the optimum designs, with respect to various design parameters, are also discussed. The formulation is programmed for interactive use on micro-computers. An example is given and results are discussed.
Overlapping Lattice Modeling for concrete fracture simulations using sequentially linear analysis Aydın, Beyazıt Bestami; Tuncay, Kağan; Binici, Barış (Wiley, 2018-04-01) Modeling concrete fracture is important in order to uncover accurately the sources of distress which lead to the damage or failure of structures. Many different numerical approaches have been used in the past employing either a smeared or a discrete cracking approach. Those models have difficulty in capturing the local nature of cracking, as well as the direction of crack propagation. Lattice modeling and peridynamics (PD) are some of the more recent nonlocal fracture simulation tools which possess advantag...
Fragility based assessment of lowrise and midrise reinforced concrete frame buildings in Turkey Ay, Bekir Özer; Erberik, Murat Altuğ; Department of Civil Engineering (2006) In this study, structural vulnerability of reinforced concrete frame structures by considering the countryspecific characteristics is investigated to manage the earthquake risk and to develop strategies for disaster mitigation. Lowrise and midrise reinforced concrete structures, which constitute approximately 75% of the total building stock in Turkey, are focused in this fragilitybased assessment. The seismic design of 3, 5, 7 and 9story reinforced concrete frame structures are carried out according to the ...
