Abstract


Moment Modulation Coefficient of beams in structural design , select a reasonable edge beam stiffness amplification coefficient and select a reasonable beam end has not been a unified value . Their reasonable value of the structure design more economical , reasonable , safe , reliable and a more important factor . Beam , side beam stiffness amplification factor directly determine the reasonable value of the beam size of the board in the structure of the force transmission and force . Elastic analysis and research framework model , this paper eventually get them beam stiffness amplification factor of 2.0 , edge beam stiffness zoom factor of 1.5 when the board of the coordinating role of the beam to achieve the best . Moment Redistribution of the reasonable value of the coefficient of the frame beam end value seems to better reflect the actual project . Its reasonable value both to design more reasonable structure , economy , it enables the structure to facilitate the construction , played a one-stop- effect . The non-linear analysis and research through the framework of this thesis beam when the frame beam end moment amplitude modulation factor structure designed to achieve the best 0.80 .
