The Influence of Lintel Beams and Floor Slabs on Natural Frequencies of the Tall Buildings Core - Numerical and Experimental Studies

This paper presents the analysis of influence of lintel beams and floor slabs on natural frequencies of tall buildings, braced by core walls. For that purpose a numerical procedure based on the Vlasov theory of thin-walled beams and transfer matrix method has been developed. In order to check the accuracy of the proposed method the calculated results are compared with those obtained by FEM and experiment. Based on these results the effects of the lintel beams and floor slabs on the natural frequencies of the tall buildings core are discussed
