Earthquake Resistance Behavior Of Frame Structure Under Those Vertical And Horizontal Earthquake Excitation Simultaneously

In this thesis, structure was solved by inputting vertical and horizontal earthquake waves with dynamic elastic-plastic time history analysis. Vertical earthquake engendering impacted stress influnced to horizontal earthquake resistance behavior. Dynamic calculation model was series-wound more particle. The vertical and horizontal earthquake waves were entered from the model's bottom that was fixed. Hysteresis curve of components was adapted subsection linearization degradation trigram model. Component's elastic stiffness, crazing stiffness, crazed stiffness, as well as crazed and high-point lateral bearing capacity were gained by approximate equation. Three kinds of the second-type field earthquake waves (vertical and horizontal earthquake excitation simultaneously) were selected in the thesis, that is, EL-Centro wave, Tianjing hospital wave and TAFT wave. Using dynamic elastic-plastic time history analysis program calculated frame structure. In order to study the influence of vertical earthquake excitation to structural horizontal earthquake resistance behavior in the situation of big earthquake, the peak value acceleration of those horizontal and vertical earthquake waves were adjusted in the course of time history analysis. After rectified, the peak value acceleration of horizontal earthquake wave turned into 400 gal which corresponded to big earthquake of the eighth degree area.
