Abstract

In high-rise buildings, lateral loads, such as wind and seismic loads, are frequently resisted by reinforced concrete (RC) structural walls. Behavior and design of fin walls at the periphery of strong core wall structure in high-rise buildings were not analyzed seriously despite their structural importance. Using elastic design/analysis methodologies for the design of high-rise RC fin walls, it is shown that elicited reinforcement ratios are too high, the economic feasibility and constructability thus becomes worse and the ductile failure mode can not be assured. In the present study, the current design process of these fin walls is investigated by analyzing their structural behavior. According to the investigation of the current design and elicited results, high-rise RC fin walls are coupled by beams although they are located on another line and apart from each other, which is main cause of high reinforcement in high-rise RC fin walls. In the present study, a literature review has been conducted to recommend the alternative design method for high-rise RC fin walls under lateral loads, and inelastic analysis has been performed to verify the design method.
