Semi‐active fuzzy control for seismic response reduction of building frames using SHD dampers
In this paper, a fuzzy rule‐based semi‐active control of building frames using semi‐active hydraulic dampers (SHDs) is presented. The SHDs are installed between the top of a Chevron bracing and the upper beam on each story to prevent damage to the structure from severe earthquakes. The set of Chevron brace and SHD is modeled as a Maxwell element that consists of a damping element in series with a spring. The rule extraction strategy for semi‐active fuzzy control is carried out by genetic algorithm (GA). The objective is to minimize both the maximum inter‐story drift and absolute acceleration responses of the structure. Interactive relationships between structural responses and damping coefficients of SHDs are established by using a fuzzy controller. GA is employed as an adaptive method to design the fuzzy controller, which is here known as a genetic fuzzy controller (GFC). To illustrate the efficiency of the proposed intelligent control strategy in application, numerical simulation for a 3‐story and a 10‐story building frame equipped with multiple dampers is presented.
