- Abstract
- A study of the sensitivity of the behavior of lightly reinforced concrete frames strengthened using the infill wall method to certain variables was conducted. These variables include the infill wall type (cast-in-place and precast), wall thickness, and the amount of anchor area and anchor type. The hysteretic behavior of the frames were predicted using three parameters and equations proposed in previous NIST work. Both quasi-static and transient dynamic analyses were performed using the program IDARC. General design guidelines are proposed based on these analyses and on observations gathered from existing experimental tests.
