摘要：

The present study investigated the dynamic behaviour of an irregular 32-storey reinforced concrete, Vancouver-style, high-rise, podium tower by assessing the influence of the floor diaphragm modelling stiffness assumptions on the structure's modal properties. The state-of-the-art diaphragm modelling approaches and their effect on structures' dynamic performance are currently related to symmetrical buildings with multiple shear walls. The influence of horizontal floor diaphragms on the dynamic behaviour of irregular, high-rise buildings with concrete core has not been sufficiently investigated either on a numerical or experimental basis. In this context, the primary objectives of the current study are: (a) to enhance the comprehension of the horizontal floor diaphragm behaviour of a high-rise building with a concrete core and, (b) to quantify the effect of varying diaphragms modelling approaches on the dynamic properties of the structure.
