Abstract

The effect of SEMI-RIGID CONNECTIONs on the behavior of structural systems always drowns the attention of many researchers to itself. In this article, the simultaneous effects of rigid and SEMI-RIGID CONNECTIONs in DUAL SYSTEMS such as braced frames are examined with nonlinear dynamic analysis. Each of the beam, column and the connections has been modeled in a three linear manner. The observed parameters in this research consist of ENERGY DISSIPATE of each story, ultimate base shear and hysteretic loops of SEMI-RIGID CONNECTIONs. The parameters are observed under different earthquakes, and the effect of height of structure, as well as number of bays is considered. It can be seen from the ENERGY DISSIPATE diagram that in DUAL SYSTEMS, the maximum observed energy between the two stories, occurred with a sudden and significant fluctuation which shows the viability of the structure in stories with the most energy absorption. The hysteretic diagram shows that the maximum energy absorption of the connection is occurred in special moment resisting frames. However the distribution of the energy between the neighboring bays of the semi rigid connection node is more fluent in dual braced systems, which prevents the energy concentration on the braced bay.
