Aims
By reading this chapter, you are introduced to:
l introduction to several retrofitting techniques suitable for RC buildings;
l comparison of three different retrofitting strategies;
l introduction to linear dynamic spectral analysis; and
l introduction to converting dominant behavior of RC shear walls.

3.1 INTRODUCTION
The presented RC building, designed as an office building and printing house,
is divided into two northern and southern parts which are connected to each
other by jack-arch roofs at each story. Expansion joints of 3–5cm in width close
to the elevator and staircase divide these two parts of the building. The building
has two basement levels, a pilot, and 8 stories and 9 stories in the southern and
northern part, respectively. The overall area of the building is nearly 22,000m 2
with the diaphragm-column which was constructed in 1969. The building was
vacant for a period of time and no as-built drawings were available. Different
views of the example building are shown in Fig. 3.1. Preliminary evaluation of
the building indicated the building was in good condition under the service
loads. Based on the special features of the building as an icon building in
newspapers publication industry, sustainable development considerations and
