    Earthquake Performance and Cost Comparison of Core Wall and Tunnel Formwork RC High Rise Buildings
    (İstanbul Kültür Üniversitesi, 2022) AMINI, MOHAMMAD IBRAHIM; Mustafa Cömert
    This study investigates the earthquake performance and cost comparison of core wall and tunnel formwork of 30 story high-rise buildings. Floor and roof systems in core wall buildings are designed to carry gravity loads and transfer these loads to the supporting beams, columns, and to footings. Furthermore, they play a key role in distributing earthquake induced loads to the lateral load resisting systems such as inner cores and columns by diaphragm action. And in tunnel formwork buildings the flat slabs are designed to carry gravity loads and directly transfer them to the shear walls and finally transferred them to the footings. This kind of buildings systems resisting earthquake-induced loads with the help of flat slab and shear walls only, without any beams and columns. Core wall building and tunnel formwork building systems are very commonly used as lateral load resisting systems which have shown very good results in past earthquakes. In the present research, the modelling of (G+29) story RC residential high-rise buildings was performed in ETABS software then the data have been transferred to PERFORM-3D analysis software for analysis purposes. Nonlinear dynamic (Time￾history) analysis has been performed, according to (ASCE 7-16) and (ACI-318-19) codes and according to (PEER TBI,2017), and (LATBSDC,2020) guidelines. The results in terms of design base shear, building periods, different mode shapes maximum displacements, drift, drift ratio, moment curvature relationship, and costs of the buildings obtained.
