Effect of Soil Classification on Seismic Behavior of SMFs considering Soil-Structure Interaction and Near-Field Earthquakes

Table 15

A comparison of the maximum drift ratio, displacement, base shear, and moment of columns due to near-field earthquakes with progressive direction-taking and in far-field earthquakes.
