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.
