Reducing behavioral cycle of hysteresis in nonlinear static analysis for concrete frame structures with special

In this article the effect of reducing the behavior of hysteresis cycles in nonlinear staticanalysis for flexural concrete ductile frames are investigating. One of the disadvantages of nonlinear static analysis is that non-linear behavior change resulting from structural components due to Kahndgy reciprocating motion is generally the approximate order. To assess the effects of 9 Kahndgy special concrete frame is used based on the design of buildings against earthquake regulations) Standard 2800, Third Edition (loaded and ETABS software are designed to analyze. Due to the special concrete in bending Frames Members of behavior are controlled mainly by the bending of the coils and Takda modified hysteresis model is used. Static and dynamic non-linear analysis software using IDARC is done to assess the damage and stigma of the model takes advantage of the famous park. Maximum shift values obtained from nonlinear dynamic analysis with the corresponding shift values obtained from objective analysis Barafzvn are compared, and results indicate that the average maximum values shift with regard to both behavior components reducing the risk level g0.2 and dealing respectively g0.25 4 % 9 % shift towards goal Barafzvn analysis increases. The modified model also Takda Kahndgy takes into effect, the index level of risk damage Bhazay g0.2 dealing with 53 % compared to the model Dvkhty increased risk levels equal to the ratio g0.25 81 %, respectively.
