Additional reinforced concrete infill walls increases the earthquake resistance of
reinforced concrete structure significantly (and practical – low cost). Indeed, the
most effective and common method to increase the existing poor earthquake
resistance of a structure is to infill reinforcement shear walls in Turkey. Therefore,
many of the latest experimental and theoretical research focused on the additional
shear walls to the structures.
In this study, non-linear behavior of added shear walls to reinforced concrete frames
that were also tested in laboratory were analyzed by ANSYS program. The program
uses finite elements method. Modeling of added shear walls and modeling
assumptions are summarized. The reinforced concrete bare frame and strengthened
with shear walls (total 8 pieces) are modeled and analyzed by ANSYS nonlinear
program subjected to reversible static loads. The outcomes are compared with the
experimental results. A weak two - story and two – span bare frame and strengthened
frame with infill walls structure is used in the current study to compare nonlinear
analysis results of ANSYS and STA4-CAD programs.
