test. Only columns in the fi rst fl oor suffered permanent damage and major
cracks during the test. Therefore, the effects of heat penetration and degrad-
ing material properties were determined only for these elements. The rest
of the elements, columns in upper fl oors, walls and beams were considered
to have no damage. Figure 14.3 shows prevalent damage to various fi rst-
fl oor columns. The pictures placed on the fi gure were taken right after the
shaking table test.
The main mechanical property of the concrete that was mostly affected
by the earthquake was its compressive strength. Concrete may experience
large non-linear deformation during the earthquake resulting in partial but
