ƒ^ƒCƒgƒ‹i‰pjF RELIABILITY ANALYSIS OF MASONRY INFILLED FRAME STRUCTURES SUBJECTED TO EARTHQUAKE GROUND MOTIONS
´˜^i‰pjF The lack of proper guidance on the seismic behavior of masonry infilled frames in most design codes has motivated this study. Considering available experimental data, a hysteretic model for the infill wall is proposed and incorporated into dynamic analysis program where inelastic response and reliability assessment are conducted under simulated ground motions. Approximate solutions for the mean and standard deviation of accumulated plastic energy and ductility factor imposed on the frame are found in closed form expressions. In general, plastic energy and ductility demands-based infilled frame reliability is found to be higher relative to bare frames depending on level and duration of input motion intensity and mechanical characteristics of the system.
