Abstract
The investigation of displacement demands of single degree of freedom models using real earthquake records compatible with TBEC-2018
Highlights
Structural design or assessment of structures can be achieved by performance and/or displacement-based approaches which first is introduced in SEAOC Vision 2000 [1],[2]
The variation of maximum displacement demands of single degree of freedom (SDOF) systems determined via dynamic analysis by using real earthquake records compatible with Turkish Building Earthquake Code (TBEC) are investigated
120 SDOF systems which represent behavior of variety of structural topologies were created by combination of different lateral strength capacity ratios, structural periods, hysteretic models and postyield stiffness ratios
Summary
Structural design or assessment of structures can be achieved by performance and/or displacement-based approaches which first is introduced in SEAOC Vision 2000 [1],[2]. Kayhan and Demir [9] used four different hysteretic models (bilinear with/without hardening, modified takeda and stiffness degrading models) to assess effect of different hysteretic models on the seismic demands of SDOF systems using code-compliant earthquakes [14]. Effect of stiffness degradation is considered using BL and MC hysteretic models In this way, behavior of different structural systems is taken into account. Stiffness degradation can clearly be observed from the MC models It can be said from the figure that displacement demands of hysteretic models are almost identical even for the different post-yield stiffness ratios. All the computations about the solution algorithm are performed by developing MSExcel macro code [31]
