Abstract
This study investigates the dynamic behaviors of RC frames with masonry infills which are constructed by different connection methods along the frame – wall boundaries. Two different connection types are considered namely, stiff connection to represent the traditional construction technique and flexible connection provided by Polyurethane PM as an innovative method. PolyUrethane Flexible Joints (PUFJ) are intended to use on both old (existing) and new (to-be-built) structures. Therefore, three single-bay and singlestory frames are numerically created; Frame A has stiff, Frame B has PUFJ around the three sides of wall except the bottom one and Frame C has entire perimeter of the wall PUFJ connections, respectively. Among the frames of PUFJ implemented ones, Frame B is for representing the usage of PUFJ on existing structures whereas Frame C shows the implementation of method in new buildings. All of the frames were exposed to constant vertical loads affecting on beams. Various horizontal loads caused by seismic excitations were also used to understand the behavior of frames under different lateral load stages. Frame stiffness values were changed by means of arranging artificial column hinges that are located either only on the bottom or on both the bottom and top of columns. Thus, different damage scenarios were able to be investigated. The results are presented in terms of natural mode frequencies and maximum displacement values.
