Design Aspect of including Infill Wall in RC Frame Design
Abstract: This study compares
analysis and design of a four story reinforced concrete (RC) frame structure
with infill wall at upper levels and open at basement level. For the analysis,
the RC frame are modeled as open frame (MOF) and infilled-frames using six
compression only cross diagonal strut (MIF-Strut), and infilled frame using
shell elements (MIF-Shell). Another model, MIF-Full, is created by adding walls
at basement level of the MIF-Strut to study the effect of wall discontinuity.
All three dimensional models are loaded with gravity load and quake load
appropriate for South Bali region. Results show that the infilled-frame models
are 4.8 times stiffer than MOF in the wall direction. Perpendicular to the
wall, however, the stiffness increase is 29%. Soft storey mechanism exists in
the absence of wall at basement level, regardless of reasonable column
dimensions.
