| Abstract: | The contents of this paper are as follows: (1) A conception of the compound element is presented, and the simplified analysis models arc set up, (2) A method for calculating the transfer matrices of the compound clcrncnt is put forward, which can also be used to clement in other forms and (3) The elastic transfer matrix for the compound elements of the shear truss structure, the plastic transfer matrix considering the nonlinear effects of the materials and the geometrical transfer matrix taking into account of P-Delta effects are derived. The results of this paper can bc used in nonlinear response analysis of multistory and tall structures. |
