Influence of constant restoring force on the dynamic response of multi-story buildings : master thesis

Abstract

The results from the nonlinear time history analysis are tabulated in this section. Each table contains the maximum parameter (interstory drift, floor acceleration, velocity, shear force, and damper force) at every floor of the model and for all the ground excitations considered in the particular analysis. The PGA for each seismic excitation are indicated in the top row of each table. The analyses are divided in three groups. In the first and second group (indicated as Model 1 and Model 2 below), the 3-story structural model presented in a previous section is utilized. In the third group (indicated as Model 3 below)the 6-story structural model, also presented in a previous section is utilized, and the Following the analysis cases are presented with graph of the hysteresis loop. First with the letter A are described the far field motions, B for the near field and with the numbers the models as presented in the previous section.
