| Abstract: | ABSTRACT
Equivalent strut approach coupled with modified Bouc-Wen model for hysteretic behavior
has been adapted for the analysis of masonry infilled RC frame. Modification of Bouc-Wen
model includes stiffness and strength degradations as well as pinching in the infill panel.
Default values for some of the parameters involved in the hysteretic model are adopted from
the manual of IDARC-2D version 6.0. A simplified program developed in substitute of
IDARC-2D is the backbone of this paper. The program assumes the beams as rigid elements
embodied in the floor slabs and the deformation of columns in linearly elastic behavior.
Four frames having the same number of stories but different number of bays are analyzed
using the program. Only the first bay, whose aspect ratio (L/H) subject to variation from 1.0
to 3.0, has been infilled with masonry. Comparative analysis of shear in the left end column
is performed for the infilled frame and corresponding bare frame. Static analysis using
fundamental period and response spectrum curve based on EBCS-8 is carried out to compare
the results of analysis of the program. |
