Seismic Response Analysis and Control of Frame Structures with Soft First Storey under Near-Fault Ground Motions

Figure 7

Interlayer displacement angles of the bottom-four-layers-plus-support structure. (a) Near-field pulsed ground motion. (b) Near-field pulse-free ground motion. (c) Average interlayer displacement angles, comparison with unsupported structure. (d) Average interlayer displacement angles, comparison with bottom-support structure.
