For this reason, the efficiency of infilled walls is examined on full scale models. Finite element analysis results show that mathematical model of concrete may change behaviour of infilled RC frames. The post-peak behaviour is especially influenced.enFinite-element-analysisOf-the-artFundamental periodCyclic responseSteel framesBehaviorOpeningsMaterial modelInfill wallReinforced concreteFinite element methodScience & technologyTechnologyEngineering, civilEngineeringReview000458198700005455671110.14256/JCE.2307.2017
