ABSTRACT
Figure 1.3 presents diagrams for two extreme situations. Figure 1.3a shows extremely stiff beams (v---+ oo ), where ZMP lies at the mid-height of each storey (s = 0·5). Figure 1.3b illustrates extremely flexible beams (v---+ 0); the diagram of
Analyses were performed for n = 6, 10 and 15 storeys subjected to uniform and inverted triangular loads (Figure 1.4); for each type of frame and loading, eight ratios v = kb/kc were considered: 0·01, 0·1, 0·5, 1, 2, 5, 10, 1000 (a total of 48 cases).
