Figure 2.29 Triple spectrum for the Kalamata, Greece 1986 earthquake: velocity (cm/ sec) along
vertical axis; acceleration (g) along left to right axis; relative displacement (cm) along right
to left axis; all versus frequency (Hz). Note: the five curves are for 0%, 2%, 5%, 10% and
20% damping.
2.5.1 Numerical example
In this section, we examine a simple, one-storey warehouse structure which essentially
supports a roof loading and is acted upon by the Kalamata, Greece 1986 earthquake
(Anagnostopoulos et al., 1986). We employ the response spectrum method and present the
solution in algorithmic form. We note here that design of heavy roof slabs with or without
strong edge beams is not recommended as good earthquake resistant design. Instead, correct
practice is to design for strong columns, weak beams and, if possible, light roof slabs.
